Description

The IQ3 controllers are Building Management System controllersthat use Ethernet and TCP/IP networking technologies. Eachcontroller incorporates a web server which can deliver user-specific web pages to a PC or mobile device running internetbrowser software. If a system is set up with the correctconnections, a user with the appropriate security codes canmonitor or adjust the controller from any Internet access pointin the world. It is also compatible with the traditional IQ systemprotocol. The IQ3 range consists of DIN rail mounting controllerswith from zero to 16 input/output points (expandable up to 96points by adding DIN rail mounting I/O modules). This flexibilitymakes them suitable for a broad range of applications. A localPC or display (SDU-xcite) can be connected to the RS232 port.

FUNCTIONALITYThis data sheet gives a general description of IQ3. Detailed information is given in the following manuals:

• SET Manual TE200147 covers IQ3’s configuration modules• IQ System Ethernet Products Engineering Manual TE200369 covers the use of IQ3 with Ethernet• IQ3 Web User Guide covers the use of Web Pages• IP Tool Manual TE200638 describes the use of the IP Tool.• IQ3 Graphical Display Page Editor Manual TE200629• IQ3 Reset Applet Manual TE200767• Site Code Manager Applet Manual TE200757

The IQ3 functionality can be divided into four sections: system, hardware, firmware, and strategy.

SYSTEM

Standard Communications

The full standard IQ3 has Ethernet, I/O bus, and RS232 ports.

Ethernet: This is the main network for the IQ3 controller. Itenables PCs to connect directly to Ethernet and communicatewith the IQ3 using IP addressing. It also enables Inter-ControllerCommunications (IC Comms - peer to peer Ethernetcommunications) between controllers. Remote PCs cancommunicate through standard IT networks (e.g. the Internet)using IP, enabling communication from anywhere in the world.The IP connection will support a web browser (thin client)running in a PC, but communication with an IQ System supervisoror tool (thick client e.g. 963, IQView) will require the use of thevirtual CNC embedded in the IQ3 controller. The strategy and allother configuration files may be downloaded to the IQ3 from SET(System Engineering Tool) across Ethernet.

I/O bus: The controller has the option of a highly reliable I/O bus.This enables expansion I/O modules to be connected to add up to80 additional I/O points (96 points in total with the 16 points in theIQ3). The bus can be up to 10 m (11 yds) or 30 m (33 yds) in length(see page 8 for details), and have a maximum of 15 I/O modules.

RS232 port: A sensor/display (RD-IQ), 4 line display panel(SDU-xcite), network display (IQView), a wireless sensor receiver(XW/R/IQ) or a local PC running a supervisor or a software tool maybe connected to the RS232 port. Only one device may be connected.This port can communicate directly with the IQ3 (address 0) or tothe IQ system network using the local supervisor CNC (see below).The RD-IQ or SDU-xcite communicates only with the local IQ3, sofor the RS232 port to operate with RD-IQ or SDU-xcite, its addressmodule local supervisor port address must be set to zero.

Data Sheet IQ3

The diagram below shows the internal Lan constructed withinthe IQ3 consisting of the controller’s CNC, local supervisor CNC(sCNC), virtual CNC (vCNC), and the virtual INC (vINC). PC B onEthernet communicates directly with the IQ3 using TCP/IP. If PCA makes a permanent connection to the IQ3’s vCNC then the IQ3alarms may be sent to the CNC, but if the connection is temporarythen the alarms can be sent directly to the supervisor as IPalarms.

Stand alone IQ3: An IQ3 prior to firmware version 1.2 could beset to ‘Stand Alone’ by the IP tool. This was to reduce the Ethernetnetwork traffic produced by for a single IQ3 (i.e. to disable pollingmessages trying to ‘find’ other IQ System devices). This featurehas been removed from firmware v1.2. If a controller’s firmwareprior to v1.2 is upgraded it will be taken out of stand alone mode.It is recommended that no IQ3 controller should be operated instand alone mode.

Multiple IQ3s: The diagram below shows two IQ3s connectedto Ethernet.

System Configurations

Single IQ3: The following diagram shows an IQ3 connected byEthernet to PC B running a web browser, and PC A running aSupervisor or Tool software. A local PC, PC C, is connecteddirectly by RS232.

Standard Communications (continued)

Networks: The IQ3 will create its own internal Lan whichincludes a node for its own controller, a CNC for its local supervisorport (if supervisor port address is set non-zero), a virtual CNC,and a virtual INC (address 126).If multiple IQ3s with the same Lan number are connected toEthernet, then an Ethernet Lan will form to include these IQ3s andtheir internal nodes. The IQ3 with the lowest IP address on theLan also assumes the INC functionality (the other virtual INCsdisappear) and is responsible for maintaining the Lan across theIQ3s. If multiple IQ3s with different Lan numbers are connectedto Ethernet then their INCs will form an internetwork (along withany EINCs/3xtends on the network).

IC Comms: The IQ3s may communicate with each other andearlier IQ (and IQL) controllers using Inter ControllerCommunications (peer to peer communications). This will use IQSystem Lan/node addressing (not direct IP addressing). IQ3 ICComms includes the use of all IQ2 IC Comms except Data Fromcomms.

Alarm Delivery: Alarms can be delivered to the local supervisorport or to a supervisor making a permanent connection to thevirtual CNC by normal IQ system comms. Alarms can be deliveredto supervisors making temporary connections to the virtual CNCusing TCP/IP by setting the supervisor’s IP address and portnumber in the alarm destination module (i.e. IP alarms). Alarmsmay also be sent by email.Note that network alarms are sent to any connected port (e.g.supervisor connected to local supervisor port, or supervisorconnected to virtual CNC).

Optional Communications

IQ System Current Loop Lan Auxiliary BoardThe optional IQ system current loop Lan auxiliary board enablesthe IQ3 to become a device on an IQ system current loop Lan.It can no longer be part of an Ethernet Lan (or internetwork).However, it will still support access using a web browser or asupervisor or tool by way of a virtual CNC, and it can still sendIP or email alarms across Ethernet. The current loop Lan auxiliaryboard is fitted in IQ3../.../LAN versions of IQ3 (henceforth referredto as IQ3/LAN).

The IQ System current loop Lan connectionenables the IQ3 to become part of an IQ systemcurrent loop Lan including IQ1s, IQ2s, otherIQ3s, supervisors, and node controllers. It

also enables the strategy file to be downloaded from SET acrossthe current loop (but not other configuration files: language,backdrop, and XNC (for /XNC/ versions only)).

Serial Auxiliary BoardThe serial auxiliary board provides an additional RS232 orRS485/422 serial port for communicating with other devices.This board is used in some versions of the IQ3../.../XNC/.. (referredto as IQ3/XNC/SER, see IQ3../.../XNC/... data sheet for moredetails)

current loop Lan auxiliary board


IQ3 Data Sheet

This is done by setting up a router IP address in the PC. In additionthe default router IP address must be set up within the IQ3, so thatTCP/IP messages from the IQ3 are transferred through the router(to the PC). The router used in each case must be on the samesubnet as the device using it (PC or IQ3).

Using a Supervisor with Multiple Sites: In the diagrambelow there are two IQ3s either side of a router.

If the IQ3s are not configured to cross the router as describedbelow, they will construct two separate networks either side ofthe router.Only one internetwork is allowed on a site, but the Supervisorcan treat the networks as separate sites and so each site mayhave an internetwork. The supervisor will change the IP addressof the IQ3 virtual CNC it is using as it switches sites. Note thatthere cannot be any IC comms between the sites.Alarms can be sent to the supervisor directly using TCP/IP.

Configuring IQ3s to Cross Routers: This is done by settingup the IQ3’s network module with the ‘Router 1’ (default router)IP address (for a router on its own subnet) and with a RemoteDevice’s IP address, and subnet mask (for an IQ3 on the otherside of the router).

In the above diagram, IQ3A is configured with the default router IPaddress and the remote IQ3's (IQ3B's) IP address and subnet mask.It will now send a message to IQ3B’s subnet through the defaultrouter. IQ3B will then reply and the IQ3A will construct theinternetwork between the two IQ3s.If more than one router is involved, IQ3B will also have to be set upto create an internetwork with IQ3A by entering its default routerIP address and IQ3A’s IP address and subnet mask.

IQ3B IQ3C IQ3D

Default Router

If several IQ3s are connected one side of a router, the unit withthe lowest IP address (cross-router master) will attempt toconstruct the network across the router. In the diagram, if thecross router master is IQ3A, it should be set up with the informationfor an IQ3 the other side, e.g.IQ3C. IQ3A will then join theinternetworks across the router. If IQ3C were to be switchedoff, the message from IQ3A will no longer reach the remainingIQ3 on the far subnet (IQ3D).

To prevent this, IQ3D’s details should also be entered in thenetwork module of IQ3A so that it can connect to IQ3D if IQ3Cis switched off.

In general with multiple routers, the details of at least one IQ3 fromevery subnet must be set up in the cross router master. The remotecross router masters will need similar details to be set up but thesemust include the details of the original IQ3.

To reduce risk of losing communications due to one device’s powerfail, the two devices with the lowest IP addresses from each subnetshould be set up in the two devices with the lowest IP addresseson the local subnet.

Up to 20 devices’ details may be entered in the network module.

System Configurations (continued)

Multiple IQ3s (continued)If the two IQ3s have the same Lan number, their two internal Lansconnect together over Ethernet.

In the network schematic it can be seen that the vINC of the IQ3with the lowest IP address takes over the INC functions for thecombined Lan, and the other IQ3 loses its vINC.

If the IQ3s have different Lan numbers they connect together byan Ethernet internetwork.

The above diagram shows such an Ethernet internetwork. Thelocal PC, C, may communicate only with its directly connectedIQ3 if the port address is set to zero, but if non-zero it cancommunicate with any other device on the IQ system network.If PC A makes a permanent connection to the IQ3’s vCNC thenalarms from either of the IQ3s can be sent to this vCNC or if itmakes a temporary connection, the alarms can be sent directlyby TCP/IP. The web browser, PC B, can make a temporaryconnection to either IQ3. The IQ3s can communicate with eachother using IC Comms.

Routers: IQ3s are able to construct an internetwork (but NOT a Lan)across a router. However, it is possible for PCs to connect to IQ3sacross routers, and to treat IQ3s separated by routers as separatesites.

Connecting a PC to an IQ3 through a Router: An Ethernetconnected PC running IQ System software (e.g. 963) may usean IQ3 vCNC through a router.

The 3xtend/EINC L may be replaced with a combination of EINC andLINC. The 3xtend/EINC L differs from the EINC in that it can operatein an automatic IP addressing environment (e.g. with DHCP) and hasa LonWorks bus connection enabling the extension of theinternetwork over Lonworks, and communication with IQLs.

3xtend/EINC L

Now the two IQ3s can connect together along with the3xtend/EINC L by an Ethernet internetwork which is extendedonto Lonworks to include the IQL’s vINC. The 3xtend/EINC L alsocontains vCNCs which appear on its Lan together with the IQ2series controllers and supervisor/software tool PC D.PC D can communicate with the IQLs, IQ2s, and IQ3s, and all thecontrollers’ alarms can be sent to PC D.

PC A can now communicate with the IQ2s and IQLs via the IQ3’svCNC. PC C on the IQ3’s local port can also communicate withthe IQ2s and IQLs (as long as the sCNC address is non-zero).However, the web browser, B, can only talk to the IQ3 (but itsdisplay pages could contain values from IQ2s and IQLs obtainedusing IC Comms).

If PC A makes a permanent connection to the IQ3’s vCNC thenthe IQ3s’ alarms may be sent to it, but if it makes a temporaryconnection (i.e. TCP/IP dial up) the IQ3s can send their alarms tothe PC using TCP/IP.

Note that the IQ3 and the 3xtend/EINC L cannot havethe same Lan number since the EINC’s Lan number(set up on its address switches) is reserved for itscurrent loop Lan.

Since both 3xtend/EINC Ls and IQ3s can appear either side ofa router, if there is a router separating the internetwork, thelowest IP addresses either side of the router may be those ofeither or both IQ3, and 3xtend/EINC L. These details would be setup in the IQ3’s network module and in the 3xtend/EINC L’sremoteEinc module. The same rules for setting up the remotedevices’ details quoted previously apply to both IQ3s and 3xtend/EINC Ls

IQ3xxB


Configuring IQ3s to Cross Routers (continued)Because IP addresses may not be fixed (see Automatic IP AddressingMode - later) it may not be possible to specify which controllers havethe lowest IP addresses, so the details should be set up in everydevice on the subnet, so that any device may be able to becomethe cross-router master. If Automatic IP Addressing mode is beingused, the remote devices will be identified by host names ratherthan IP addresses.

It is recommended that the details of two devices (eitherIQViews, 3xtend/EINC Ls, or IQ3s) in the network fromeach subnet the other side of a router should be set upin every device in the network (either IQViews, 3xtend/EINC Ls or IQ3s) on the local subnet. For increased reliability,details of additional devices should also be set up.

Multiple routers: The default router can be any router on thesame subnet as the device using it. It will pass the message toa router on the remote IQ3’s subnet.

Internet Access: Because the Internet uses TCP/IP addressing,the 963/IQ3 communication can operate over the Internet.Company Internet access is normally protected by a firewallwhich is usually the responsibility of the company's IT department.The firewall will need to be set up to allow messages throughthe port addresses being used for sending and receiving IQSystem messages. Additionally the firewall may be set up eitherto pass messages through or to redirect them. If redirection isbeing used, then the messages are sent to the firewall IP addressand the firewall must be set up with the relevant IQ System IPaddress (e.g. IQ3 vCNC, 3xtend/EINC L vCNC, or IQ3’s own IPaddress for web pages) so it can pass them on. If using animpermanent ISP connection (e.g. using a dial up modem) ateither 963 or IQ3 end, the ISP (Internet Service Provider) mustsupport reverse dial up.

Note that IQ3 to IQ3 networking communications will not operateacross a firewall (i.e. virtual networks cannot be built acrossfirewalls).

IQ3 with 3xtend/EINC L: The diagram below shows the additionof an 3xtend/EINC L to Ethernet. The 3xtend/EINC L supports anIQ System current loop Lan which may contain IQ1 or IQ2 seriescontrollers.

The network schematic shown above is almost the same exceptthat the INC has been removed. The IQ3/LAN is unable to performINC functions on the current loop Lan, (i.e. it cannot sit on theinternetwork).The other features remain: a supervisor or tool (A) cancommunicate by TCP/IP using the vCNC , a web browser (B) candirectly access the IQ3 using TCP/IP, and a supervisor or tool cancommunicate using the local supervisor RS232 port (sCNC).

IQ3/LAN on the Lan: Once another IQ (IQ1, IQ2, or IQ3) isconnected to the current loop, the two IQs form a Lan. This canthen be extended onto an internetwork in the normal way usingan INC type node (e.g. INC2, LINC, 3xtend/EINC L).

Dial Up Networking:

This method of communicating by a PSTN connection makes useof modem routers. They connect together the segments ofEthernet by PSTN.

IQ3 with 3xtend/EINC L (continued)

Note that if an IQ3 is added to an existing system with3xtend/EINC Ls either side of a router and has thelowest IP address then its virtual INC will becomethe cross-router master and it must have the remotedevices’ details set up; failure to do this will stopsystem communications across the router.

The plain EINC (as opposed to 3xtend/EINC L) should not be usedon a system using auto-addressing.

IQ3 and TMN: The IQ3 can use a TMN connected to an3xtend/EINC L’s current loop network. The 3xtend/EINC L shouldoperate in internetwork extension mode (i.e. device address=>100) which provides a current loop internetwork with anextension on Ethernet. However, this will only give normal IQSystem Communications (i.e. text communications), it cannotprovide web pages. Note that in this example the 3xtend/EINC L’sLonworks connection has been left unused.

Data Sheet IQ3

Automatic IP Addressing ModeThe IQ3 is able to operate in a system where the IP addressesare automatically allocated by a DHCP (Dynamic Host ConfigurationProtocol) server (i.e. the IP addresses are not fixed).

IP Addressing Mode Parameter: The IP Addressing Modeparameter (in network module) is set to ‘Enter Manually’ fortraditional manual entry with a fixed IP address, and is set to‘Obtain Automatically’ (default setting) for the IP address tobe set automatically by the DHCP server.

DHCP Operation: If set to Obtain Automatically, when thecontroller powers up it will inform the DHCP server which canthen provide it with:

IP AddressSubnet MaskRouter 1 (default router)WINS Servers (1 to 5)DNS Servers (1 to 5)

(These parameters cannot now be changed by SET unless IPAddressing mode parameter is set to ‘Enter Manually’.)

Link/Local Operation: If the controller is in automatic IPaddressing mode and the DHCP server fails to respond, the IQ3will enter link/local mode where it will negotiate its IP addresswith the other devices on its Ethernet segment. There may besome time delay between DHCP server failure and the controllerentering link/local mode as it will only prompt the DHCP serverafter its lease has expired which may be a long time. The firstIQ3 to go into link/local will cause the other IQ3s on its segmentto go into link/local.A PC (running supervisor or tool software) should be set up forauto-addressing. On DHCP failure it may take a very long timeto enter link/local and be able to comunicate with the IQ3s, andthere will appear to be communication failure. This can be avoidedby power cycling the PC which will cause it to enter link/local onpower up.

Summary of IP Addressing Modes

In link/local mode the IP addresses start at 169.254.0.0, thesubnet mask will be set to its default (255.255.0.0), and theRouter 1, WINS servers, and DNS servers will remain at their lastsettings. Any devices wanting to communicate with an IQ3 in link/local using IP addressing must be on the subnet so defined.

IQ3/LAN on the Lan (continued)If a 3xtend/EINC L is used instead of an INC, then the internetwork(or a segment of it) can exist on Ethernet. This would enableEthernet Lans of IQ3s to be part of the same system network asan IQ3/LAN.The 3xtend/EINC L also has a LonWorks bus connection enablingthe internetwork to also be present on the Lonworks bus, andhence connect to LonWorks Lans of IQLsThe diagram below shows an 3xtend/EINC L being used toconnect the current loop Lan to an Ethernet internetwork. AnEthernet Lan of IQ3s is also connected to the internetwork byan IQ3’s vINC.

Host name: Because the IP address is no longer fixed inautomatic IP addressing mode, the IQ3 has an additionaladdressing parameter, the Hostname, which is fixed. When theIQ3 powers up it sends its host name to a WINS (WindowsInternet Naming Service) server. If a device wishes to communicatewith the IQ3 it will send the IQ3’s host name to the WINS serverwhich will return the associated IP address. For example the IQ3IP alarm Destination IP Address (alarm destination module) maybe set up with a host name in which case the IQ3 will submit thehost name to the WINS servers set up as above, starting at 1,up to however many are set up (maximum 5), until it receivesback an IP address which it will then use as the alarm address.

If a WINS server does not exist, the host name can be used overthe local segment only (i.e. not across routers).

The host name can also be used to communicate with the IQ3 ifthe IP Addressing Mode parameter (in network module) is set to‘Enter Manually’. This provides a user-friendly way of identifyingthe controller rather than remembering its IP address.

Default Host Name: If the host name has not been set up, theIQ3 will power up with a default host name which is a functionof its MAC address (‘Trend’ plus the last six digits of the MACaddress e.g. TREND_00_14_D0). The default host name willalways be operational (as well as its Hostname if it has been setup), unless the Default Hostname parameter (network module)has been set to ‘Disabled’.

Communication across the Internet: If a device (e.g.supervisor) wishes to communicate across the Internet with anIQ3 on a system with automatic IP addressing, then the firewallserver either has to be able to use the host name, or the IQ3’sIP address must be fixed.

Fixing the Controller’s Address on a DHCP controlledSystem: It is possible for the IQ3 to operate in a DHCP regimewith a fixed IP address by setting up the DHCP server so that italways gives that particular IQ3 the same IP address. Analternative is to set the IQ3 IP Addressing Mode parameter (innetwork module) to ‘Enter Manually’, and set its IP addressoutside the range of the DHCP server.

Email Server Address: Because the Email Server Address isno longer fixed on a DHCP system, it must be set up (in thenetwork module) to a host name or an Internet domain name.Thus when an email alarm is to be sent the Email Server IPAddress is resolved by either a WINS server or a DNS (DomainName System) server.

Crossing Routers if DHCP is operating: In the DHCP regime,if the internetwork is to cross a router(s), the Remote Devices(1 to 20) IP addresses should be set up as host names. This willenable the IP addresses to be obtained from the WINS servers.

If the network is to cross a router, the details of twodevices in the network from each subnet the other sideof a router should be set up in every device in the networkon the local subnet. For increased reliability, details of additionaldevices should also be set up.

Note that if any communication using a host name crosses arouter(s), then a WINS server address must be set up.

IQ3 Data Sheet

Power Supply: The IQ3 can be supplied in two input power supplyversions./100-240 :100 to 240 Vac at 50 or 60 Hz. Power requirement

is 46 VA maximum.Note that a switch or circuit breaker (240 Vac, 3 A) must beincluded in the supply to the unit and in close proximity to it, andit must be clearly marked as the disconnecting device for the unit./24 :24 Vac at 50 or 60 Hz, 24 to 60 Vdc (36 Vdc

maximum for /UL versions). Power requirement is40 VA maximum.

A summary of the minimum and maximum power requirementsis given below:

The minimum power is for the core electronics without any I/Oauxiliary power or additional I/O modules. The maximum powerfor the IQ3xcite/000 includes core electronics and maximumauxiliary supply consumption, for the IQ3xact/012 andIQ3xcite/016 it also includes maximum I/O consumption; themaximum for the IQ3xcite/96 includes core electronics, maximumI/O consumption, and maximum auxiliary supply of 700 mA (whichincludes power to the I/O bus).

Fusing: The 24 Vdc combined supply to the IQ3’s own I/Ochannels, the I/O bus, the RS232 connector (e.g. to powerSDU-xcite), and the auxiliary supply output is protected by aself-resetting electronic circuit breaker. The part of the 24 Vdccombined supply which supplies the RS232, and the 24 V auxiliarysupply output is limited to 150 mA.The analogue output P bus is protected by a 1.6 A self resetting multifuse.The power supply is protected against catastrophic failure bya non-replaceable fuse. The analogue output circuitry is protectedagainst the wrong connection of a non-isolated external supplyby a non-replaceable fuse. If either non-replaceable fuse blows,the controller should be sent back for repair.The I/O modules have protection as described in the I/O module section.

Battery Backup: The strategy configuration and data (logs,alarms) are stored in the unit in nonvolatile memory (Flash). A‘supercap’ is used to maintain the real time clock (time and date).In the event of power failure this will support the clock for 6 days(typically). Note that the supercap needs about 2 minutes toreach full charge after power is applied.Optionally a battery board (XCITE/BBC) can be fitted into the unit;this will support the clock for several years in the event of powerfailure (e.g. for Timemaster, see Firmware/Timemaster).If the battery hasn’t been discharged, it should be replacedroutinely every 5 years. The battery (type CR2032) can bereplaced after turning the power off and removing the auxiliaryboard cover (while the battery is not in circuit the supercap willmaintain the real time clock).

IQ system Current Loop Lan Optional Auxiliary Board:The IQ3/LAN (IQ3../.../LAN) is supplied complete with a Lanauxiliary board fitted in the auxiliary board slot, and with a specialauxiliary board cover which enables access to the auxiliaryboard switches and connectors.

IQ3

Box: The controller box is DIN rail mounting and must be fittedinside a cabinet. The input channel links are accessible by meansof a clear polycarbonate cover which can be unclipped using ascrewdriver. The I/O bus connector has a hinged plastic cover.The auxiliary board cover can be levered off by inserting ascrewdriver between the back of the cover and the main unit.It has a rear DIN rail clip.The digital input LEDs, the output LEDs, and the three controllerstatus LEDs can be viewed through the clear polycarbonate.

I/O Bus: This feature is only available on the expandable IQ3(IQ3XCITE/96). The IQ3xcite is connected to an adjacent I/O moduleby a rigid connector. It can be connected to a remote I/O module bya flexible cable. The connection is made by opening the flap,plugging in the connector, and then closing the flap over the cable.The last module on the I/O bus must be correctly terminated (seeI/O Modules section). The IQ3xcite is provided with a terminator, andeach I/O module is provided with a rigid interconnector).

Connectors: Other than the screen terminals, which are singlepart, two part connectors are used throughout to facilitateinstallation. The screw terminals are of a rising cage clamp typeto facilitate good connections. Each input channel has a terminalfor cable screen connection. The internal cable screen earthing(grounding) terminal bus is connected to the controller earth(ground) by a soldered link on the board. If required to segregatethe screen earth (ground) from the controller input power supplyearth (ground), it may be connected to a separate external earth(ground) by lifting the cover and cutting the screen earth (ground)link and making a connection between the internal screen busterminal and an external earth (ground).


Link/local Default Operation: Both IQ3s and 3xtend/EINC Lsare set to automatic IP addressing by default. If a group of thesedevices are connected together on an Ethernet segment (withoutDHCP, WINS servers) they will power up in link/local and auto-negotiate their IP addresses. If they have been set up with deviceaddresses and Lan numbers they will construct a Trend IQsystem network. A supervisor or system tool running on a PCon the same segment will be able to communicate with them usinghost names (if the PC is set up for auto-addressing).Such a system cannot form a network across a router.

Note that it is recommended that link/local only be used asnormal operation on a single segment system, (not across arouter). Also note that any other device communicating with theIQ3 (e.g. a supervisor PC) must also be in link/local.

Servers: If the IQ3’s IP address settings are to be supplied bya DHCP server, the server must be installed on the same segmentas the IQ3. On a multi-segment system a single DNS server maybe use providing it has a connection to each segment, i.e. mutipleconnections.The server must be capable of downloading either or both (asappropriate, see below) the WINS server address, and the DNSserver address.

If host names are being used for IP addressing across a router,then a WINS server must be installed on the system.

If email alarms are being sent, and the email server address isidentified by Internet domain name, then a DNS server must beinstalled on the system.

Data Sheet IQ3

Note that if an external 24 Vac/dc power supply is used, it must bededicated to I/O channel use, and it must comply with the relevantEMC and safety standards.

The external supply can be either 24 Vac or 24 Vdc, but if theoutput devices require a mix of 24 Vac and 24 Vdc a decisionwill have to be made over which supply to connect to the P bus;the other supply will need to be provided by external wiring.

Note that the installer should note whether the P bus is 24 Vac,or 24 Vdc and only connect the appropriate loads.

The following checks should be made:

• The maximum current 700 mA (550 mA) available from24 Vdc combined supply is not exceeded.• The 150 mA supply to the RS232 and Auxiliary outputsupply is not exceeded.

The following areas of consumption need to be considered:Input/output Channels: The universal input channels need only

be considered if they are used for loop powered current,IL, in which case they consume a maximum of 20 mA each.The output channels will also consume a maximum of20 mA each, but their likely consumption is a lot less thanthis and can be calculated on an individual basis ifnecessary.

I/O Bus: The I/O bus supplies 24 Vdc through one of the busterminals. This can be used to supply the adjacent I/Omodules, or the I/O modules can be wired to an externalpower supply. If the main controller is used to supply anyI/O modules their consumption must be considered in theauxiliary power calculation. I/O module powerconsumption is considered later.

IQ system Current Loop Lan Optional Auxiliary Board(continued):The auxiliary board also contains the circuit for a backup batteryso it can also fulfil the function of XCITE/BBC as described above.However, the CR2032 battery is not supplied so must bepurchased separately if a battery backup option is required.The board contains the normal hardware for an IQ systemcurrent loop Lan node:

Address/Baud rate switch: The address on the Lanis set by poles 1 to 7 in range 1, 4 to 9, 11 to 119 and must beunique on the Lan. The strategy address module Local Addressparameter monitors the address switch settings and is read onlyfor IQ3/LAN. The baud rate is set by poles 8 to 10 in the range9k6, 19k2 and must match the other nodes on the Lan (it can alsobe read in Network Module 2).Note that zero address reset is not implemented on IQ3.

Network terminals: The network terminals facilitateconnection of 4 wire cables (enabling a ‘weaving’ connectionmethod).

Indicators: The standard LEDs are fitted (TX, RX, andnetwork OK).

Bypass relays: The board contains 2 changeover relayswhich bypass the receive and transmit circuitry and maintainnetwork integrity during power fail.

Serial Auxiliary Board: This board is fitted to IQ3/XNC/SER(IQ3../.../XNC/SER) versions of IQ3, see IQ3../.../XNC/... datasheet for details. This board also supports the battery backupfacility in the same way as the IQ system current loop Lanauxiliary board (see above).

Indicators:I/O Channels

Input LEDs: (yellow) Each input channel has an LED tomonitor the input state when the input channel is set toa digital input. The LED will illuminate when the associatedinput contact is closed.

Output LEDs: (yellow) Each output channel has an LEDwhose light intensity increases with output voltage.

Core functionWatchdog ( ): (red) On if controller has a software fault (i.e.

EthernetOK : (green) Normally called LINK on Ethernet systems. ON

indicates a good Ethernet connection. If OFF indicatesfaulty Ethernet connection.

RX: (yellow) Flashes when packet of data is being receivedacross the Ethernet.

24 Vdc Combined Supply: The 24 Vdc combined supplysupplies the IQ3’s own input/output channels, the I/O bus, theRS232 connector (e.g. to power SDU-xcite), and the 24 Vdcauxiliary output supply terminals. The total available current is700 mA (reducing to 550 mA for /100-240 version if the 230 Vacinput power supply is less than 200 Vac). The PSU has thermaloverload protection and the combined supply is protected by aself resetting electronic circuit breaker.

The input and output channels are current limited at 22 mA each.The part of the combined supply used by the RS232 connectorand the auxiliary output supply is current limited to 150 mA(typical). The auxiliary output supply can be linked into the Pconnector to supply auxiliary power for use by output devices.

IQ3 (continued)

24 Vdc Combined Supply (continued):RS232 supply out: The SDU-xcite consumes 15 mA, the RD-IQ 10 mA,

the XW/R/IQ (wireless receiver) 50 mA, but IQView (or a PC)does not take any power from the RS232 connector.

Auxiliary output supply: The 24 Vdc auxiliary output supplyterminals can be used to supply interfaces directly, andcan also be linked to the P bus.Note that the 24 Vdc auxiliary output supply voltage candrop to about 20.7 V under full load.

Output Channels Power Bus: The P bus, which supplies the Pterminals adjacent to the output channels, can be connectedto an external supply, in which case the P bus consumeszero current from the auxiliary output supply. If the P busis linked to the auxiliary output supply, the total currentsupplied from these terminals will have to be considered.

Example: An IQ3XCITE/96 with an XCITE/IO/4UI/4AO I/O module,SDU-xcite, and its own I/O as follows: 4 loop poweredcurrent inputs, 4 voltage inputs, 2 digital inputs, and4 voltage outputs into 5 kΩ loads, 2 voltage outputs into1 kΩ loads. The P bus is linked to the 24 V auxiliary outputsupply and one of the P terminals supplies a 6RM at86 mA The I/O module consumes 72 mA. What remainingauxiliary current is available?

I/O Channels4 loop powered current inputs at 20 mA = 80 mA4 voltage inputs = 0 mA2 digital inputs = 0 mA4 voltage outputs at (5 kΩ is 2 mA) = 8 mA4 voltage outputs at (1 kΩ is 10 mA) = 40 mA

I/O bus module consumption = 72 mARS232 SDU-xcite = 15 mAAUX output supply (linked to P bus) = 86 mA

Total = 301 mA

Since the unit is supplied at 230 Vac, the maximum 24 Vdc auxiliarycurrent available is 700 mA. So remaining current available is 700-301 = 399 mA. This could be used by additional I/O modules.If this were not sufficient an additional power supply could beused to supply the I/O modules (see I/O bus section below).

However, RS232/auxiliary output supply consumption amountsto 101 mA (15+86); this is limited at 150 mA, so only 49 mAremains available from the 24 Vdc auxiliary output supplyterminals. If this is not sufficient an additional power supply couldbe used to supply the P bus as described above, releasinganother 101 mA for use by the 24 Vdc auxiliary output supply.

I/O Channels:IQ3XCITE/00: Zero input/output channelsIQ3XACT/12: 6 universal inputs and 6 analogue outputsIQ3XCITE/16: 10 universal inputs, and 6 analogue outputsIQ3XCITE/96: 10 universal inputs, and 6 analogue outputs plusadditional I/O channels can be provided by connecting I/O modulesto the I/O bus to provide up to a maximum of 96 channels.

Universal InputsChannels 1 to 10 - linkable for digital (D), current (I), thermistor(T), or voltage (V) inputs.

The P output terminals are used to supply power to the outputdevices. The internal power bus (P bus) is protected by a 1.6 A solidstate self-resetting multifuse. The P bus is normally supplied fromthe IQ3 24 Vdc auxiliary output supply through the external linkshown above (supplied fitted by default) but if required it can besupplied from an external isolated 24 Vac/Vdc power supply. Thecontroller is protected against the wrong connection of a non-isolated external supply by a non-replaceable fuse.

Ethernet: The controller should be connected to an Ethernet hubor switch using Cat 5e unshielded or shielded (UTP or FTP) cableand RJ45 plugs (shielded or unshielded appropriate to the cable).The following products are available:CAT5E UTP LSZH 305M: 305m, 333yds Cat 5e UTP (unshielded)cableCAT5E FTP LSZH 305M: 305m, 333yds Cat 5e FTP (shielded) cableRJ45 PLUG UTP/10: Unshielded RJ45 connectors (pack of 10)RJ45 PLUG FTP/10: Shielded RJ45 connectors (pack of 10)A local PC (Ethernet) can either be connected to an adjacent porton the hub, or can be connected directly to the IQ3 Ethernet portusing a standard Ethernet cable in conjunction with a crossoveradapter (XCITE/XA).

Displays

The IQ3 controller can be used with IQView, SDU-xcite, and RD-IQ displays.Note that the NDP is not compatible with IQ3; it will not recognisean IQ3 connected to its network.

IQView: The IQView is a touch screen network display (colouror mono) which can be either surface mounted or rear panelmounted. In addition to showing all the normal strategy items, itcan access directories, timezones, and alarms, and users canbe set up with configurable access rights. It can be connectedto the IQ3 either by Ethernet or by RS232. The Ethernet connectioncan either be by the IQView’s own virtual CNC or by an externalvCNC (e.g. the IQ3’s). The RS232 connection enables the IQViewto communicate either only with that IQ3 (if local supervisor portaddress is zero), or with the network (if local supervisor portaddress is non-zero).

For D, Ix, V, and T connect between (in)N and 0 V.For IL, connect between 24 Vdc and (in)N.

SDU-xcite: The SDU-xcite is a wall mounting 4 line display. Inaddition to showing all the normal strategy items, it can accessdirectories and the IQ3’s alarm log. It connects to the IQ3 by itsRS232 port, and it can communicate only with that IQ3, so thelocal supervisor port address must be set to zero.

RD-IQ: The RD-IQ is a wall mounting temperature sensor and 3digit display. It has the following variants:

RD-IQ/K: Room display with local temperature sensorand setpoint control

RD-IQ/KOS: As RD/K plus occupation override andoccupation status display.

RD-IQ/KOSF: As RD-IQ/KOS plus fan speed control.It connects to the IQ3 by its RS232 port, and it can communicateonly with that IQ3, so the local supervisor port address must beset to zero. By default it accesses fixed strategy items (althoughthese can be changed using the front panel buttons or SDUconfiguration software, SDU Tool):

I/O Modules

The expandable version of the IQ3 (IQ3XCITE/96/..) has theoption of connecting additional I/O modules to the I/O bus.

• A maximum of 15 I/O modules can be connected.• A maximum of 96 points (16 points in the IQ3xcite and80 expansion points) can be used.

• The controller and its I/O modules are to be fitted insideenclosures.

• No spurs are allowed on the I/O bus.• If a single fully earth (ground) screened and bonded contiguousmetal enclosure is used, then the total I/O bus cable length canbe up to 30 m, 33 yds (this covers the use of a multiple sectionelectrical control cabinet e.g. Form 4 enclosures).

However, if any other type of enclosure is used, or the I/Obus runs between enclosures, then the total I/O buscable length can be up to 10 m, 11 yds.

(For the calculation of cable length, rigid interconnectorscan be ignored.)

• Multiple enclosures must be earthed (grounded) to acommon earth (ground) point according to latest IEEregulations.

The current range of modules consists of:8 Universal Inputs (/8UI/)4 Universal Inputs (/4UI/)4 Universal Inputs and 4 Analogue Voltage Outputs (/4UI/4AO)2 Universal Inputs and 2 Analogue Voltage Outputs (2UI/2AO/)8 Relay Outputs (/8DO/)4 Relay Outputs (/4DO/)8 Analogue Outputs (/8AO)4 Analogue Outputs (/4AO)16 Digital Inputs (/16DI)8 Digital Inputs (/8DI)8 Relay outputs with Hand/Off/Auto (/8DO/HOA/)4 Relay outputs with Hand/Off/Auto (4DO/HOA/)

I/O Bus: The I/O module has a hinged plastic cover each side forconnection of the I/O bus, enabling the bus to be daisy chainedby the I/O modules. A short rigid interconnector (XCITE/IC) isavailable for adjacent modules. An interconnector is suppliedwith each I/O module, spare interconnectors are available(XCITE/IC/5 pack of 5).

The bus should be terminated at the furthest end from the controllerbetween Data Hi and Data Lo terminals with a 122 Ω resistor. Aterminator is supplied with the IQ3xcite controller, and spareterminators (XCITE/TERM/5 - pack of 5) are available.

The rigid bus interconnector includes a ground connection.

For modules further apart within a metal enclosure, plug in screwterminals (XCITE/CC/10 - pack of 10) are available, enabling themodules to be wired together. Belden 3084A cable should beused, the ground connector should be earthed (grounded) locally,and the cable screen should be grounded at the controller end.

Note that the cable core colours shown are for the recommendedcable, Belden 3084A.

This type of cable (type A) connects the right side of one moduleto the left side of another. It can be used for two sections of DINrail in a panel as shown below:

The diagram of cable type B (left to left) below shows the cableentry directions correctly, so the signal direction is reversed.

No spurs are allowed. For example, in the multisection panel belowthe DIN rail sections are connected in series to form one single lengthof bus with termination at the farthest end from the controller.

The IQ3xcite can supply 24 Vdc to the I/O modules through theI/O bus 24 Vdc terminal. The available current from the controller’scombined 24 Vdc supply can be calculated as described abovein the IQ3xcite/24 Vdc Combined Supply section.

Alternatively an external 24 Vdc supply must be used if:• There are more than 6 I/O modules*• The main controller combined supply would be overloaded.

*Note that this rule does not apply to /8AO, /4AO, /16DI, /8DI, /8DO(serial number M3D4 C0 508 012 or greater) /4DO (serial numberM3D8 C0 508 0136 or greater), /8DO/HOA, /4DO/HOA moduleswhich do not need to be included in this module count.

If an external supply is required, the normal bus connection between24 Vdc terminals is not made, instead an isolated 24 Vdc supply iswired between the 24 Vdc and 0V terminals.The maximum current that can be passed through an I/O modulethrough the 24 Vdc and 0 V terminals, from one module to the next,is 2.5 A.

Note that if an external 24 Vdc power supply is used, its outputmust be isolated from earth (ground), and it must comply withthe relevant EMC and safety standards.

For adjacent modules theXCITE/PCON/50 cable facilitates theconnection of the external powersupply; it leaves a 10 mm (0.39”) gapbetween the modules.

For non adjacent modules the following connections should beused (type A connection shown). This is facilitated byXCITE/PCON/1000, a 1 metre (1 yd 3”) cable.

The PSR range of DIN rail mounted auxiliary power supplies (e.g.1.3 A or 2.5 A) are available. They have isolated outputs.

I/O Module 24 Vdc Supply: An I/O module can either take itssupply from the main controller or from an external supply asdescribed above.An external supply must be used if more than 6 I/O modules areconnected (except for /8AO, /4AO, /16DI, /8DI, 8DO/HOA,4DO/HOA, and newer versions of /8DO, /4DO as describedabove), or if the main controller combined 24 Vdc supply currentwere to be overloaded. This second condition depends on thetotal current consumed by the I/O module, and the current availablefrom the main controller (calculated as described in the maincontroller auxiliary supply section above).The I/O bus connector 24 Vdc terminal supplies the I/O module’score electronics, its input/output channels, and the 24 Vdcauxiliary supply terminal (present only in I/O module with analogueoutput channels) which is limited to 150 mA (typical). The auxiliarysupply is provided so that it can be linked into the P connectorto supply auxiliary power for use by output devices.

Data Sheet IQ3

Note that if an external 24 Vac/dc power supply is used, it mustbe dedicated to I/O channel use, and it must comply with therelevant EMC and safety standards.

The external supply can be either 24 V ac or 24 Vdc, but if theoutput devices require a mix of 24 Vac and 24 Vdc a decisionwill have to be made over which supply to connect to the P bus;the other supply will need to be provided by external wiring.Note that the installer should note whether the P bus is 24 Vac,or 24 Vdc and only connect the appropriate loads.

The following checks should be made:

• Calculate the maximum current consumed from the I/O bus24 Vdc terminal for use in the main controller’s auxiliarycalculation.

• Check that the 150 mA supply to the Auxiliary Supply is notexceeded.

The following areas of consumption need to be considered:Core electronics: 20 mA is required to supply the I/O module’s

electronics.Input/output Channels: The universal input channels need

only be considered if they are used for loop powered current,IL, in which case they consume a maximum of 20 mA each.Each channel is individually current limited.The analogue output channels require 3 mA each fortheir LED plus the output rated at 20 mA maximum, but theirlikely consumption is a lot less than this and can be calculatedon an individual basis if necessary.Relay outputs consume 10 mA each

Output Channels Power Bus: On I/O modules with analogueoutputs, the P bus which supplies the P terminals adjacentto the output channels can be connected to an externalsupply, in which case there is zero consumption from the I/Obus 24 Vdc terminal to any output devices. If not, the totalcurrent supplied from these terminals will have to be takeninto account.

Example: An XCITE/IO/4UI/4AO I/O module has 2 digital inputs,and 2 external powered current inputs, and 4 voltage outputsinto 1 kΩ loads. The P bus is linked to the 24 V Auxiliary OutputSupply and one of the P terminals supplies a 6RM at 86 mA.

I/O Channels2 external powered current inputs = 0 mA

2 digital inputs = 0 mA4 voltage outputs at (1 kΩ is 10 mA + 3 mA) = 52 mA

Core Electronics = 20 mAAuxiliary Output Supply (linked to P bus) = 86 mA

Total = 158 mA

The total consumption from the 24 Vdc supply terminal is 158 mAwhich should be considered when calculating the load on themain controller’s auxiliary supply. If the main controller cannotsupply this current, an external 24 Vdc supply should beconnected to supply the I/O module.

The Auxiliary Output Supply consumption amounts to 86 mA; thisis limited at 150 mA, so 64 mA remains available from the 24 VdcAuxiliary Output Supply terminal. If this were to exceed the150 mA limit, an additional power supply should be used tosupply the P bus as described above.Note that the 24 Vdc auxiliary output supply is normally about19.8 V and will drop to about 18.4 V under full load.

Screen Earthing (Grounding): On I/O modules with universalinputs, the screens for universal input channels are normallyconnected to the module ground, but they may be separatelyearthed-grounded (if required to segregate the screen earth-ground from the I/O module ground).

This is similar to the controller screen earthing (grounding), see

IQ3, connectors section. There is a separate link for each groupof four channels (i.e. the 8 universal input module has two links).

I/O Module Enclosure: The I/O module enclosure is DIN railmounting and must be installed in a cabinet. It has clear polycarbonatecovers over both the upper and lower terminal sets to enableaccess to the channel links and the address switch. The strips canbe unclipped using a screwdriver and clipped back in position afteruse. The I/O terminals are protected by clear polycarbonate flip upsafety covers. It has a rear DIN rail clip.The digital input LEDs, output LEDs, and the three controllerstatus LEDs can be viewed through the clear polycarbonate.

I/O Module Address Switch: The address switch consists ofa hexadecimal switch, 0 to 9, A, B, C, D, E, F. Selecting address zerodisables the module. If there is an address clash on the I/O bus, theI/O bus fault LEDs on all the modules with the same address willflash; a module’s address can be corrected by setting its addressswitch to other addresses until its LED stops flashing.When setting up the input and output channels in sensor, digitalinput, and driver software strategy modules, the I/O moduleaddress and the channel number have to be entered; the maincontroller is referred to as module zero.

This can be an open collector or an open drain (FET) input. Thecollector or drain must be able to sink 3 mA. When the transistoror FET conducts, the digital input will be ON.

This type of digital input can monitor the state of a 24 Vac signal.In this example it will be ON when the load (e.g a fan) is powered.

Indicators: The I/O modules have similar indicators to thecontroller: Universal input (digital), Analogue output, Power, andWatchdog. The Relay output, Analogue output (/8AO, /4AO)Excess Aux. Current, Digital input (/16DI, /8DI), and Input PolarityError indicators are described above.The I/O Bus LED will illuminate continuously for an I/O bus fault(e.g. check for short circuit between Data Hi or Data Lo and eitherof the power lines). If the LED flashes at 1 second intervals, theI/O module has not been in receipt of any valid comms for 30 secs,and the module will switch off any outputs. If the LED flashesfaster it indicates an address clash as described above (I/OModule Address Switch); this duplicate address check is doneafter power up or after changing the address switch.

Logic Input


I/O Module Channels: The universal inputs have similarconnections to those in the main IQ3xcite.

Analogue Outputs: The analogue outputs have a similararrangement to the main controller with the 24 Vdc auxiliaryoutput supply and the P bus. The /8AO auxiliary output supplyterminals can supply a maximum of 300 mA (shared betweenboth sets of terminals); if this is exceeded the current limits andthe two Excess Aux. Current LEDs (red) will illuminate. The /4AOcan supply a maximum of 150 mA and it has one Excess Aux.Current LED (red) which will illuminate if this limit is exceeded.

Relay Outputs: The relay outputs are single polechangeover, and have a relay output status LED (yellow) whichis ON when the relay is energised.

Relay Outputs with Hand/Off/Auto: The relay outputswith Hand/Off/Auto (HOA) facility are based on the standardrelay outputs but also have a 3 position HOA switch per channel.This switch can be set to Hand ( H , manually overridden ON),Auto (A, under automatic control from the strategy), or Off (O,manually overridden OFF). In addition to the yellow output statusLED there is a red LED which is ON when the output is manuallyoverridden (i.e Hand or Off). The output status LEDs are nearestto the terminals and the overridden LEDs are towards the centreof the unit. The output can thus be in one of four states whichare shown in the table below along with the switch and LEDstates.

The input will be on when the input LED (yellow) is ON, and thisis when the contact closes or AC voltage is applied. Thiscorresponds to an open collector transistor or an open drain FETbeing ON, or a logic input sinking current from the terminal (lowstate).There is an Input Polarity Error LED for each bank of 8 inputs. ThisLED (red) is ON if one (or more) of the digital inputs are suppliedby an ac voltage, which has been connected with the wrongpolarity.

The volt free contact input has a nominal wetting current of 2.5 mA.The input is ON when the contact is closed..

FIRMWARE

Upgrade

The firmware in the IQ3 CPU board, baseboard, and XCITE I/Omodules can be upgraded over Ethernet.

Strategy

The IQ3 strategy modules are based on the traditional IQ paradigmwith minor changes to increase capability and efficiency.The .IQ3 strategy file is created and downloaded using SET.SET facilitates strategy creation by providing an indexed libraryof pre-configured strategy blocks; these may be viewed, printed,or edited to suit the user.The strategy file and the other configuration files (language,backdrop, and XNC (IQ3/XNC only)) can be downloaded acrossEthernet (FTP) but only the strategy file can be downloadedacross the current loop Lan (IQ3/LAN only).An Ethernet download requires the PC running SET to beconnected to Ethernet, and to communicate with the IQ3 usingthe IQ3’s IP address (SET will actually obtain the IP address fromthe IQ3 using the IQ System Lan number and device addresses).

The .IQ3 strategy file can be backed up in the same way (i.e.using SET over Ethernet or current loop Lan - IQ3/LAN only). Notethat IQ3 firmware v1.3 requires SET v6 or greater.A local PC (Ethernet) can either be connected to an adjacent porton the hub, or can be connected directly to the IQ3 Ethernet portusing a standard Ethernet cable in conjunction with a crossoveradapter (XCITE/XA).

If IQ3 communications fail completely, the IQ3 can be reset tofactory defaults by using the Reset Applet within SET. Use ofthis applet will remove all strategy data (including passwords),alarm and sensor logs, IP addressing, and remote Trend Devicemodules; the IQ3 will have to be set up from scratch.The IQ3 web server provides pages (HTML) which enable limitedconfiguration from a web browser; most module parametersmay be viewed and adjusted, but the strategy structure (moduleinterconnections, creation or deletion of a module) cannot bemodified from a web browser.

Addressing

Each IQ3 has a unique MAC (Media Access Control) addressallocated to its Ethernet node. The IP Tool (SET auxiliaryapplication) enables the IQ3 IP address (and other Ethernetparameters), and the IQ System Lan number and device addressto be set up. This requires the PC running SET and the IP Tool tobe connected to Ethernet as described above.


Data Sheet IQ3

Flexible module numbers: The number of each type ofmodule may be adjusted to match the requirements of theapplication as long as the memory capacity of the controller isnot exceeded. As a general guideline the IQ3 has a capacity atleast equal to a fully utilised IQ251.

The available capacity is measured in brIQs. The total availablecapacity in an IQ3 varies with the type and is given in the tablebelow (along with maximum logging record numbers).

Notes:# The actual size in (numbers of brIQs) varies with module type.The largest size is shown here.‡ The sequence table takes 106 brIQs, the table includes 600 steps.* The time zone brIQ count allows for an average of 20 exceptions.IQ3 has an absolute limit of 4000 modules; the limits imposed bySET prevent this from being exceeded. The IQ3 also limits thenumber of destination modules to 8 as shown above. Network,Program and Option modules have zero brIQs. The XNC interfacemodules also have zero brIQs but the TCL application consumesbrIQs as defined in the IQ3/../XNC data sheet.

In SET, as the modules are created, a tally is kept of the brIQs usedand the amount available to be used; an indication of this can beviewed. If the limit is exceeded, then SET will prohibit the creationof further modules.It is possible to create modules which are not numerically sequentialso module lists can be non-continuous (e.g. L1, L2, L5, L7...).

Each type of module has memory requirement in brIQs as listedbelow; SET also limits the number of modules as shown in the table.

Addressing (continued)

The IP Tool can automatically fetch the details of all the IQ SystemIP devices (3xtend/EINC Ls and IQ3s) on its own segment ofEthernet; it can also fetch details from devices the other side ofa router by reading the remote Trend Device modules from an IQ3or 3xtend/EINC L (alternatively the user can enter the remotedevice’s IP address by hand).The IP Tool also enables the Virtual CNCs to be configured.

Strategy Modules

The IQ3 strategy modules include the following IQ2 modules:

Type (sensor type), Sensor, Digital input, Function, Logic, Loop,Sequence table, Knob, Schedule, Switch, Time, Zone, OSS,User, Address, IC Comms, Alarm history, Plots, Time zoneexceptions (partial implementation of Calendars), Display andDirectory modules, Driver, page, group, route, destination.

Although the analogue and digital arrays are not included, thenew analogue modules and digital byte modules can be used forIC Comms and to support IQ2 strategies. (Also not included are:Critical alarms, Autodialling modules, and Calendars other thantime zone exceptions.)

The following features indicate the differences between IQ3and IQ2 modules:

Longer labels: Module labels will now have a maximum of 30characters, although to maintain backwards compatibility, in somecircumstances only 20 may be used; for example only 20 charactersare retained in the alarm log. If using an SDU-xcite (< v1.01 firmware),the label length must be limited to 20 characters; SDU-xcite v1.01will truncate the label to the first 20 characters.

Module overrides: All input/output strategy modules (drivers,sensors, digital inputs) have an override input. This can beconnected to a digital input from a module, or can be overriddenby SET Live Edit, or from a web page. If controlled by a connection,the module will be overridden while the connection is true. Ifoverridden by SET or a web page, the module will be overriddenwhile the address module override timer is true; once an overrideis set, the address module override timer should be set to therequired time, and it will start counting down to zero at whichpoint the override will be removed. This enables an engineer tocheck the Heating and Ventilating equipment operation confidentthat the override will be automatically removed.Each module has an Override Output Status (the override inputwhich could be a connection), and an Override Value/Status(which is the value or status the output will assume while theoverride is on)

Plot: The IQ3 logs will have 8 digit resolution. However, IQ3 v1.xcan only use existing communications protocol which limits theresolution to 5 digits. The protocol also limits the sensor numberof full precison logs to between 1 and 99 (although logs ofsensors >99 can be seen using webpages).Note that IQ3 logging capacity varies with version as shown in the tableopposite (in ‘flexible module numbers’ section); e.g. the IQ3xcite has500,000 logging records (e.g. 500 off 1000 point logs). SET limits thenumber of logging records used to these limits.

Time Zones: The time zone has a normal week (standardweek), and exceptions. The exceptions are the IQ3 equivalentof IQ2xx calendars and enable dates to be set up with differentoccupation times (see Web Pages, Time Zones). Each time zonecan have up to 50 exceptions. Each day or exception can haveup to 20 on/off times (10 on, 10 off).

User module: The user module is extended to include securityfor web access; it can also define which contents of the websitecan be seen by a particular user. There are Name (30 characters)and Password (30 characters) parameters. The module also aHome page (URL) that can be defined for each user.

IQ3 Data Sheet

FIRMWARE (continued)

Direct module interconnection: Modules are no longerconnected through nodes but are connected directly to eachother. Thus each module input is set up with a connection to itssource. In SET this is done graphically by dragging a connectionbetween the modules.

Module parameters are either inputs, outputs, or internalparameters.Analogue and digital array nodes that were effectively moduleinputs and outputs (e.g. sensor alarm bits) are now moduleinputs and outputs in their own right.In the webpages modules’ details (see later), the sourceconnection is shown against an input. All an output’s destinationsare also shown, having been determined by the controllerfirmware.If nodes are required to upgrade an IQ2 strategy to IQ3, analoguemodules and digital byte modules will have to be created by theuser after conversion (see IC Communications below).Nodes which were read/write now have inputs and outputs(e.g. knobs now have input, V, value). Multiplexing of nodes isachieved by allowing many module outputs to connect to onemodule input.All IQ3 module inputs have a value as well as a connection. Soa constant input is achieved by setting the value, and not settingthe connection. An input which is to be ignored (e.g. an input toan averaging function module) has its value deleted (as opposedto a zero value, which is valid); in SET this is set by a tick boxon the input.

Event driven strategy: Normally modules will be entered in thesequence table like IQ2 modules. There is an absolute maximumof 600 modules per second (i.e. 600 modules in the sequencetable with a 1 s cycle time).However, a section of strategy may be event driven where thevalues travel through the interconnected modules from one endto the other. This is used to replace the ‘fast digital inputs’ featureavailable in IQ2. For example to count the 1s pulse, a logic countermodule must be event driven. A module is set to be event drivenby taking it out of the sequence table using SET. Note that it isrecommended that an event driven strategy should not containa loop moduleAn event is defined as a change on the input to an event drivenmodule. Counting both sequence table modules and events as‘items’, there can be up to 900 items serviced per second ofwhich up to 600 can be sequence table modules.Note that event driven strategies cannot include feedback (i.e. aconnection from an output back into an input of a precedingmodule). This will cause the section to become non event driven.

A strategy that includes feedback with ‘fan out’ (i.e. which createtwo output events for one input event) would cause the 600module/s limit to be exceeded, and would generate a ‘SequenceTable Overrun’ alarm. The section becomes non-event driven.

Any module which is sequenced or event driven may be disabled(e.g. for commissioning purposes) by setting its disable parameter‘on’.

IC Communications: The IQ3s may communicate with eachother and IQ2 (and IQL) controllers using Inter ControllerCommunications (peer to peer communications) using IQ SystemLan/node addressing (not direct IP addressing).

As can be seen in the table below, IQ3 controllers will respondto and generate all Data To, Global To, and Visitor comms, butcannot operate with Data From comms

Note that IC Comms with IQ1 v3 controllers are similar to thosewith IQ2 controllers except the IQ3 can only receive messages(i.e. Data To from IQ1), not send them. However, IC Comms withIQ1 v4.1 or greater controllers can be considered to be thesame as those with IQ2 controllers.

The receipt of IC Comms with an analog node or digital bit/byteis implemented by creating analogue node or digital byte modulesduring the strategy creation process on SET.

Alarms: The IQ3 has no critical alarms. Item alarms are as forIQ2, but there are additional general alarms as indicated in theAddress module section below. Network alarms are the sameas IQ2 but are only sent to the local supervisor port.Item and general alarms may still be sent in coded, text alarm, orattribute format. The ‘roll round’ alarm log has a maximum lengthof 300 alarms after which the earliest alarms are lost. For codedalarms the protocol limits the item number to 255 maximum. Fortext alarms the maximum item label length is 20 characters(although the 963 can be setup to use labels previously learnt).The alarm destination module has three types, Trend Address,IP address, and Email. IP address and Email types are new in IQ3.Sending an alarm to an IP address requires the IP address (orhostname) to be set up in the alarm destination module along withthe port number of 963. Sending an Email alarm requires both theTo Email address and a From Email address (used to set anaddress to which replies can be sent) to be set up in the alarmdestination module and the Email Server Address to be set up inthe address module. The Email Server Address can be set up asan IP address, an internet domain name, or a hostname; theinternet domain name or host name require a DNS server addressor a WINS server address respectively to be set up in thenetwork module so that the name can be resolved.

Data Sheet IQ3

• Addresses 240.0.0.0 to 247.255.255.255, reservedfor experimentation and development.Further addresses may not be suitable for a particularsystem; check with the company’s IT department.

Subnet Mask: (read/write, default 255.255.0.0) The maskused to mask the IP address to produce a subnet. All IQ3sand EINCs must be on the same subnet (and hence havethe same subnet mask) in order to construct a Lan orinternetwork. IQ3s on the other side of a router may havea different subnet mask. An invalid subnet mask (e.g.0.0.0.0) should not be used.Further subnet masks may not be suitable for a particularsystem; check with the company’s IT department.

UDP port: (read/write, default 57612) The UDP (User DatagramProtocol) port defines the IP port used by the IQ3. All theIQ3s and EINCs used to create Lans and an Internetworkmust use the same UDP port number. IQ3s and EINCs canbe set up with different UDP ports to create two completelyseparate systems on the same subnet.

Router 1: (read/write, default 255.255.255.255) Thisspecifies the IP address of a router to which messagesare sent if the destination address is not on the localsubnet (i.e. default router). It should be set to the IPaddress of a router on the same subnet as the controller.

Note that a change to address parameters (IP, subnet, UDP,router, Lan, outstation, Vcnc) causes a general reset.Note that IP address, Subnet mask, UDP port, Router 1 arenormally configured by IP Tool.

The following parameters are concerned with DHCP operation(see Automatic IP Addressing’ section above):

Hostname: (read/write, up to 15 characters, set to a functionof the Ethernet MAC address by default*). The host nameof this IQ3; when the host name is submitted to a WINSserver, the server will return the named device’s IPaddress. If the host name has been configured the IQ3will respond to both its host name and its default hostname*. It may be used for communication betweendevices on the same Ethernet segment (i.e withoutcrossing routers) without resort to a WINS server.

*Disable Default Hostname: (read/write, set ‘Off’ by default)If set ‘On’, the default host name can no longer be usedto communicate with this IQ3 (e.g for security reasons).

Auto Addressing Mode: (read/write, set to ‘ObtainAutomatically’ by default) Should be set to ‘ObtainAutomatically’ if operating in a DHCP regime; in this modewhen the IQ3 powers up it will inform the DHCP serverwhich will then provide it with: IP address, Subnet Mask,Router 1, WINS Servers (1 to 5), DNS Servers (1 to 5).If the DHCP server fails to respond, the IQ3 will enter link/local mode where it will negotiate its IP address with theother devices on the Ethernet subnet and set thefollowing: subnet mask to default and Router, WINS andDNS servers to last settings. If set to ‘Manual entry’ theIP addressing parameters need to be set manually.

WINS Servers 1 (to 5): (read/write, set by default to 0.0.0.0)The IP address of a WINS server. Must be set up if usinghost names across routers.

For alarm delivery by email:Email server address: (read/write, set blank by default) The

IP address, internet domain name, or host name of theSMTP (Simple Mail Transfer Protocol) server to be usedfor sending email type alarms.

DNS Servers 1 (to 5): (read/write, set by default to 0.0.0.0)The IP address of a DNS (Domain Name System) server.Must be set up if using an internet domain name for theemail server when setting up an email alarm destinationtype. This server will respond to a domain name (e.g.atrendsite.com) with its IP address.

If the IQ System network on Ethernet is to span routers theRemote Devices’ address(es) and Subnet mask(s) must be setup (see ‘Configuring IQ3s to Cross Routers’ section above).

FIRMWARE (continued)

Alarm bits: As explained above the sensor alarms bits areoutputs from the sensor module. They also accompany theanalogue value so that for example as the value passes througha function module it can take the correct action on input failure.

Timemaster: Timemaster functionality is different from IQ2 as itis a separate parameter (Timemaster on or off ) as opposed to beingswitched on by ‘daylight hours change’ parameter in IQ2.

The time synchronisation message is now a global/global textcomms message which will synchronise all IQ1 (post 1989), IQ2and IQL controllers. The IQ3 does not provide the time keeperfunctionality; this was only required for IQ90’s which did nothave a battery backed real time clock, and they should besupported by a pre-IQ3 timekeeper controller on their own Lan.The IQ3 real time clock is able to ascertain if it has lost its timesynchronisation due to the supercap discharging after a powerfail, and if so the controller will request time synchronisation fromthe timemaster.Note that an IQ2 controller will not respond to this request soon a combined system (IQ3s with other IQs) an IQ3 must be thetimemaster.The supercap support for the clock will expire after about 6 days(typically) of power failure, so a system of IQ3s would needre-synchronising after this time. The timemaster IQ3 should befitted with the battery option board which would support theclock for several years.

I/O Module: On power up the IQ3xcite will discover all the I/Omodules connected to the I/O bus and create a strategy I/Omodule for each one; each module will contain Actual type(e.g.XCITE/IO/8DO), State (not present, self testing, operational,recoverable fault, unrecoverable fault). This aids commissioningeven before the strategy is downloaded. The I/O configurationmodule number is the same as the address of the hardwaremodule on the bus (i.e. I/O configuration module 2 is for hardwaremodule at address 2). This module will disappear on a powercycle unless it is editted (e.g. given a label).In SET the module is set up by selecting Device/IO setup andentering the ID (address) and type; a SET created module persiststhrough power cycles.

Display and Directory Modules: These are used to generatethe IQ3 display pages as described in the Web Pages, GraphIQssection below.

Network Module: In IQ3 v1.3 all of the Ethernet communicationparameters are contained in the Network 1 module.Note that Network 2 module only exists for IQ3/LAN and containsread only LAN baud rate parameters (as set on the board switches).

Ethernet MAC: (read only) The IQ3’s MAC (Media AccessControl) address; a globally unique address programmedinto the Ethernet device within the controller. IPTool canaccess the IQ3 using this address and set up its IPaddressing.

XML Server Enable: (set by default to 0). Placeholder forfuture development feature.

The following parameters are described in the rest of the documentloosely as IP addressing. See IQ System Ethernet ProductsEngineering Manual TE200369 for details.

IP address: (read/write, default 128.1.1.3) The IP (internetprotocol) address of the controller. Must be unique. It isnormally specified by the persons responsible for the ITsystem. The following IP addresses should not be used:• Addresses 127.x.x.x, reserved for loopback.• The non masked part of the address cannot be all 1’sor 0’s e.g. if address is 1.2.x.x and subnet mask is255.255.0.0 then x.x. cannot be either 255.255 or 0.0.• Addresses 224.0.0.0 to 239.255.255.255, reservedfor multicast.


IQ3 Data Sheet

Address Module: The address module has the followingparameters additional to those described in the IQ EngineeringManual, 90-1533.

Site GUID: (read/write, blank by default). A world wideunique machine readable site identification code (GUID= Global Unique Identifier). All controllers on the samesite should have the same code. Used by 963 to identifythe source of alarms which have been sent by an IQ3directly to the 963’s IP address. Set up using SET for newprojects, or using the Site Code Manager applet withinSET for upgrading existing sites.

Site Name: (read/write, up to 30 characters, defaults to theMAC address of the IQ3) A human readable site identifier.All controllers on the same site should have the samename. Sent as part of email alarms to identify alarmsource. Set up in the same way as the GUID.

External I/O count: (read only) The current number of externalchannels connected

brIQ Capacity: (read only) The total memory in the controlleravailable for strategy (and /XNC TCL application). Thiswill vary with IQ3 option, and firmware version. It ismeasured in ‘brIQs’ - see above.

brIQs Used: (read only) The amount of memory used for thecurrent strategy (and /XNC TCL application). It is measuredin ‘brIQs’ - see above.

Plot Memory Size: (read only) Memory capacity for plots inbytes; one plotting record (1 value at one time) requires5 memory units

Web Pages

The web pages all have a menu bar across the top of the page withthe following selections: Login*, Alarms, Time Zones, Modules,GraphIQs. (*Login changes to Logout once the user has logged in).The user may be limited as to what he can see (see ‘guest’ user inlogin section below).

Standard web pages are provided to support all the selectionsexcept for the ‘GraphIQs’ which depend on the configuration ofthe display and directory modules.Selecting ‘Modules’ produces the module selection buttons downthe left side of the page from which the module’s list page maybe selected. This lists all the modules of that type, and byselecting a particular module, its details page may be viewed. Onthe details page the module parameters may be viewed orchanged.

Welcome Page: A fresh user coming into the IQ3 ‘website’ willbe given the status of ‘system guest’ and the password userlevel of 100 which gives total access.However, if there are any users set up (i.e. the IQ3’s security isenabled), then the ‘system guest’ user level will be -1, which allowsthe module details and parameters to be viewed but not adjusted.If the ‘guest’ user has been set up without a password, then thefresh user will be given the status of ‘guest’ with the level as setfor ‘guest’ user.

Login: The user may select Login from the menu bar.

The User Name and Password should be entered. These mustcorrespond to those set up in a user module. The user moduledefines the user level (i.e. what can be changed), the home pagefor that user and the web pages that the user can access. If thehome page is set up, it will be displayed once the OK button ispressed after a valid user name and password are entered. Thehome page can be one of the directory pages, which in the IQ3 canbe graphical display pages, and the directory pages can be linkedto allow navigation; the home page could also be any other HTMLpage (e.g. any of the standard IQ3 pages, or a company website).Once the user has logged in, the Login selection changes to Logout.The user should logout and close the browser after completing asession in order to preserve security. It is possible to let the browserstore the name and password so that the user need not log in onre-entry to the IQ3 website, but this must be done with care so asnot to impair the password security.If a password is forgotten, the ‘Forgotten you password? ClickHere’ should be selected and a password key will be given This canbe used to contact Technical Support to obtain a new password.

Alarms: The user may select Alarms from the menu bar.

The alarm log gives a list of the basic alarm attributes from thealarm log. It gives the source module reference (e.g. S1, sensor1), and its label, the type of alarm (e.g. high), the value at the timeof alarm, the time (time and date), the reported state (occurredor cleared), and the current state of the alarm message (whetherit is active or completed). Clicking on Module Ref will display thesource module details.

Time Zones: The time zone selection gives the list of time zones.

The zones are listed together with the label, the current state(O=unoccupied, I = occupied), and hot links to the normal weekand exceptions.Selecting the normal week enables the individual days to be setup and copied from one to the other. Additional occupationperiods can be added to a day. Note that to create a period, twotime zone change times should be added, one to switchoccupation on, and one to switch it off.Selecting the exceptions enables exceptions to the normal weekto be set up (these correspond to the IQ2 calendars).

An exception day can have a number of start/stop times set upand can have a start date and stop date. The exception day caneither be set to off, or to the next occurrence of start /stop dateonly (after which it will set itself off), or to every occurrence ofthe start/stop dates (i.e. off, next, every). Each exception alsohas a priority level (1-top to 6 -bottom) so that if exceptions clash,the highest priority wins.

IQ3 Data Sheet

The actual module buttons shown depend on the current passwordlevel. (A password with level 80 or above will give a full list of moduletypes). Clicking on a module button will produce a list of the modulesof that type which enables a module to be selected to view itsparameters, and, if authorised, to change them.

Note that access by the web pages only enables the module’sdetails to be changed; changes to the strategy structure(i.e. module interconnections, and creation/deletion of modules)can only be done by text comms or by a strategy download(e.g. using SET).

Module List: The list of modules shows all the instances of thatmodule type that have been created.

In the case of adjustment modules (i.e. knobs and switches), thevalue/status can be changed (i.e. by ‘wipe and type’) and thechange implemented by clicking on the tick icon, .On both module lists and module details pages, the refresh icon

causes the values to be refreshed, and the graph icon(adjacent to the appropriate value) allows the graph page

to be viewed.Clicking on a module from the list displays the module’s details page.

In the case of the knob, the label, value, units, PIN level, and topand bottom of range can be changed, but the destination, page,and x, y coordinates cannot be changed.Module destinations and sources can be clicked on to jump to thedetails page of the destination or source module. This is done byclicking on the connection arrow, but for destinations, theparticular destination can be selected from a drop down listbefore selecting the arrow.

Graph Page: The graph page gives a graph of the values in theplot module, and a spot value which can be moved along thegraph trace.The list of values used to create the graph can be seen byselecting the list tab. As the point is moved along the graph itspoint value is displayed. A section of graph can be enlarged bythe zoom feature (left click and drag, right click to reset). Thegraph display can also chart (display a graph of live values asthey occur).

Web Pages (continued)

Modules: Selecting Modules from the menu bar produces themodule selection buttons down the left side of the screen.

Module Details: The module details page allows all the moduleparameters to be viewed, and the parameters to be changed(other than those that refer to module interconnections).


Data Sheet IQ3

Width and textalign: The width can be constrained orauto sized, and at can be aligned left, centre, or right.URL: The text can have an internet link under it so whenit is selected the browser will jump to that URL (i.e.another website which could be another IQ3 controllerin which case the user need not log in again).

Dynamic text has the following parameters:Item: The text comms code for the dynamic parametersto be displayed.e.g.

Web Pages (continued)

GraphIQs: Selecting GraphIQs from the menu bar will displaythe first graphical display page. A directory ‘navigator’ in the topleft corner facilitates moving from page to page.

The IQ3 graphical display pages are based around the Displayand Directory modules’ structure. The directory module canhave a graphical backdrop onto which the display modules’ textcan be placed. The display modules have x and y coordinateparameters which enable them to be located at appropriatepoints in front of the backdrop.The directory navigator is automatically generated and placedin the top left corner. The current page displayed is highlighted,and the page above (parent), those on the same level (siblings),and those below it (children) in the hierarchy are also shown.

The pages are entered in SET, the backdrop being imported intoSET as a graphical file. Set will allow a maximum backdrop sizeof 200 kbytes, and maximum capacity for all backdrops of2 Mbytes (it will warn if a backdrop exceeds 100 kbytes). Notethat backdrops can be cached in the browser reducing re-displaytime.

Directory Modules: The directory module has a backdropparameter which defines the filename of the graphicalfile; SET facilitates the use of .JPG and .GIF files asbackdrops. An additional backcolour parameter definesa colour to be used as background if there is no backdropor the browser cannot access the picture. The dynamicitems are automatically refreshed and the refresh ratecan be defined.

Display Modules: As well as x, y coordinates the display moduleshave a type parameter which can be set to either staticor dynamic text.

Static text has the following parameters:Label : The displayed text.Forecolour/Backcolour: The text colour and itsbackground colour which can be transparent.Fontname and font size: The font can be either Serif,Sans-serif, Cursive, Monospace, or Verdana and itssize is specified in points.
