NetLinx™Architecture

NetLinx open network architecture is the Rockwell Automation strategy of using opennetworking technology for seamless, top-floor to shop-floor integration. The networksin the NetLinx architecture DeviceNet, ControlNet™, and EtherNet/IP™ speaka common language and share a universal set of communication services. NetLinxarchitecture, part of the Integrated Architecture, seamlessly integrates all thecomponents in an automation system from a few devices on one network to multipledevices on multiple networks including access to the Internet helping you toimprove flexibility, reduce installation costs, and increase productivity.

EtherNet/IP is an open industrial networking standard that supports implicit andexplicit messaging and uses commercial, off-the-shelf EtherNet equipment andphysical media.

ControlNet allows intelligent, high-speed control devices to share the informationrequired for supervisory control, work-cell coordination, operator interface,remote device configuration, programming, and troubleshooting.

DeviceNet offers high-speed access to plant-floor data from a broad range of plant-floor devices and a significant reduction in wiring.

Selecting theDeviceNetCommunicationInterfaceFor These Features: Remember: Select:

Cost-effectiveElectrically connects the Main Network to the I/O modules,which are connected on the POINTBusEach I/O module counts toward the allowable limit of 63 nodeson the Main NetworkNo configuration to the 1734-PDN necessary since it istransparent to the Main Network Each POINT I/O module on the Main Network counts as a

separate node.Network distance limitations.A POINT I/O expansion power supply is not permitted.

1734-PDN

Acts like a 1734-PDN, but use a DeviceNet node number for thebuilt-in 8 inputs and 8 outputsAppears to the Main Network as a 1734-PDN with a single, 16-point module attachedAny of the I/O modules may be attached in the same mannerthey are added to a 1734-PDN

1734D Series

Behaves as a slave device on the Main Network and a master onthe POINTBusAllows a group of I/O modules on the Subnet to act as a singlenode on the Main NetworkRSNetWorx™ for DeviceNet software is needed forconfiguration of the 1734-ADN on the Main Network and thePOINTBusConfiguration on the POINTBus consists of a scan list that is verysimilar to those used in all of the DeviceNet master scannermodules

All POINT I/O modules count as a single node on the MainNetwork.The Main Network distance is acceptable.POINT I/O expansion power supplies are permitted to add morePOINT I/O modules.

1734-ADN

Acts like a 1734-ADN, with additional capabilitiesHas a second, Phoenix-style connector that extends the Subnetoff the module, so that any DeviceNet-capable device could beconnected to a subnet and scanned by the 1734-ADNXNode numbers of the devices on the POINTBus and subnetwould not count against the 63 slave nodes allowed on the MainNetworkData from these devices would be included in the data beingsent to/from the 1734-ADNX on the main networkNetwork on the second connector is electrically isolated fromthe Main Network and can be used to extend the total DeviceNettrunk line distance

For example: with thick round media at 125K baud, you could runa maximum of 500m to a 1734-ADNX on the Main Network. Youcould then wire an additional 500m of cable on the subnetconnector and double the distance of the network. Rememberthat this Subnet needs terminating resistors and a 24V dcpower connection, the same as any other DeviceNet network.

All POINT I/O modules and some third-party field devices countas a single node on the Main NetworkDevices on the Subnet and the Main Network need to beconnected at different baud rate speeds or use differentsampling methods (i.e., COS, polled, etc.)The Main Network distance is not acceptable, and additionaldistance is required.An expansion power supply may be required to add moremodules.POINT I/O expansion power supplies are permitted.

1734-ADNX

POINT I/O offers four interfaces for connecting to DeviceNet. Refer to the followingtable.

About the 1734DSeries

With the introduction of the 1734-232ASC module, the amount of data to betransferred over the Subnet could become substantial. This could also occur with the1734-ADNX and the standard DeviceNet devices connected to its Subnet connector. Itis important that the total amount of data coming from the Subnet does not exceed thedata capability of either the 1734-ADN or -ADNX.

250 bytes (248 data + 2 bytes command info) for output data (used as either COS,cyclic, or poll)

250 bytes (248 data + 2 bytes status info) for polled input data

250 bytes (248 data + 2 bytes status info) for COS/cyclic input data

8 bytes (6 data + 2 status info) for strobe input data

The data coming through the 1734 adapter combined with the other data from theMain Network cannot exceed the data capability of the Main Network, master scanner.If this occurs, you will need multiple master scanners on the Main Network and theI/O modules on the Subnet will need to be split between multiple 1734-ADN or -ADNXadapters. With the 1734-PDN, the multiple masters on the Main Network will be ableto communicate to separate groups of modules on its Subnet through the same 1734-PDN, so no additional adapter would be necessary.

The 1734D Series is a set of DIN-rail mounted products with an integrated DeviceNetcommunication interface, various combinations of onboard I/O points, removableterminations, and a POINTBus expansion port.

The DeviceNet interface presents the integrated I/O as a single DeviceNet node whileexpansion I/O modules will appear as separate nodes.

The 1734D Series includes a non-isolated DeviceNet communication interface. The24V dc from the DeviceNet connection powers a non-isolated dc/dc converter thatgenerates +5V dc. This +5V dc powers the 1734D Series electronics and connects tothe PointBus port to power the expansion I/O electronics.

Whatever field power you supply is connected to the internal field-power bus. Forexample, if 120V ac is applied to the power connections, there will be 120Vac applied to the modules through the internal field-power bus.POINT I/O modules to the right of the 1734D products will also have that internalpower bus voltage applied, unless you use a 1734-FPD to interrupt and change thefield power-bus voltage.

Digital I/O Modules Choose digital I/O modules when you need:

Input modules. An input module responds to an input signal in the followingmanner:Input filtering limits the effect of voltage transients caused by contact bounce and/orelectrical noise. If not filtered, voltage transients could produce false data. All inputmodules use input filtering.Optical isolation shields logic circuits from possible damage due to electricaltransients.Logic circuits process the signal.An input LED turns on or off indicating the status of the corresponding input device.

Output modules. An output module controls the output signal in the followingmanner:Logic circuits determine the output status.An output LED indicates the status of the output signal.Optical isolation separates module logic and bus circuits from field power.The output driver turns the corresponding output on or off.

Surge suppression. Most output modules have built-in surge suppression toreduce the effects of high-voltage transients. However, we recommend that you usean additional suppression device if an output is being used to control inductivedevices, such as:relaysmotor starterssolenoidsmotorsAdditional suppression is especially important if your inductive device is in serieswith or parallel to hard contacts, such as:push buttonsselector switches

The 1734 digital I/O modules support:

a wide variety of voltage interface capabilities

isolated and non-isolated module types

point-level output fault states

choice of direct-connect or rack-optimized communications

Choose analog, thermocouple, and/or RTD I/O modules when you need:

Analog, Thermocouple, and RTD I/OModulesThe POINT I/O analog and temperature I/O modules support: on-board, channel-leveldata alarming (four set-points per channel); scaling to engineering units; channel-level diagnostics (electronic bits and LEDs); and integer format.

Individually configurable channels allow the module to be used with a varietyof sensors.

On-board scaling eliminates the need to scale the data in the controller.Controller processing time and power are preserved for more important tasks, suchas I/O control, communications, or other user-driven functions.

On-line configuration. Modules can be configured in the RUN mode using theprogramming software or the control program. This allows you to changeconfiguration while the system is operating. For example, the input filter for aparticular channel could be changed, or a channel could be disabled based on abatch condition. To use this feature, the controller and network interface mustalso support this feature.

Over- and under-range detections and indications eliminates the need to testvalues in the control program, saving valuable processing power of the controller.In addition, since alarms are handled by the module, the response is faster and onlya single bit per channel is monitored to determine if an error condition hasoccurred.

Ability to direct output device operation during an abnormal condition.Each channel of the output module can be individually configured to hold its lastvalue or assume a user-defined value on a fault condition. This feature allows you toset the condition of your analog devices, and therefore your control process, whichmay help to ensure a reliable shutdown.

Ability to individually enable and disable channels. Disabling unusedchannels improves module performance.

Selectable input filters allows you to select from several different filterfrequencies for each channel that best meets the performance needs of yourapplication based on environmental limitations. Lower filter settings provide greaternoise rejection and resolution. Higher filter settings provide faster performance.Note: The analog modules provide four input filter selections; RTD andthermocouple modules provide six.

Selectable response to broken input sensor. This feature provides feedback tothe controller that a field device is not connected or operating properly. This allowsyou to specify corrective action based on the bit or channel condition.

High Accuracy. The modules share a high accuracy rating of ±0.1% of full-scaleaccuracy @ 25°C.

Using TemperatureModule Alarms

Over-Range Alarm

Under-Range Alarm

Level Alarms

Each channel alarm can be configured individually.

The channel over-range alarm is set if the input is greater than the maximumtemperature (thermocouple or RTD range dependent), millivolt (+75V) or resistance(600Ω) range value, or above the maximum range of the thermocouple or RTD.

The cold-junction compensator has its own over-range alarm. If the CJC temperaturegoes above 70°C, the over-range alarm is set.

The channel under-range alarm is set if the input is less than the minimumtemperature (thermocouple or RTD range dependent), millivolt (-75 mV) orresistance (10Ω) range value, or below the minimum range of the thermocouple orRTD.

The cold-junction compensator has its own under-range alarm. If the CJC temperaturegoes below 0°C, the under-range alarm is set.

There are four level alarms:

low

low-low

high

high-high

When the channel input goes below a low alarm or above a high alarm, a bit is set inthe data table. All alarm status bits can be read individually or by reading the channelstatus byte (bits 2-5 for channel 0; bits 10-13 for channel 1).

POINT I/O temperature modules are capable of detecting and communicating thefollowing electronic conditions:

over-range alarm

under-range alarm

level alarm (low-low, low, high, high-high)

open-wire alarm

Cold-JunctionCompensation(1734-IT2I Only)

When using thermocouples, cold-junction compensation is required at thetermination of the thermocouple wire. Cold-junction can be accomplished in threedifferent ways:

enter an estimated temperature

use a 1734-TBCJC mounting base (recommended)

use external cold-junction compensators

Entering an estimated temperature is the least accurate way for cold-junctioncompensation. Using external compensators is the most expensive way, while using the1734-TBCJC provides the easiest and most accurate method.

An open cold-junction compensator causes the input point to the maximumtemperature value for the selected input type. This will cause an alarm to be set. Oncethe alarm is issued, it remains active as long as the input signal is faulted (abovemaximum).

Cold-Junction Enable (1734-IT2I Only)

Set this bit to enable or disable the cold-junction linearization. If enabled, the propercold-junction compensation value will be applied to the selected thermocouple. Ifdisabled, the data (CJ temperature) will still be available but not applied to the input.If the 1734-TBCJC is not available, this parameter should be set to disabled. A cold-junction value can be added using the cold-junction offset parameter.

Noise Filtering(1734-IR2 Only)

You can select the type and amount of noise filtering on each individual channel.

notch filter of analog to digital converter

first-order, low-pass digital filter

Choose the filter that provides you with the update and step response that most closelymatches your system requirements.

Open-Wire Alarm

The module has the ability to check for a broken or detached wire. In any mode, if abroken/detached lead is detected, the data value is forced to maximum and the over-range alarm is set. Once the alarm is issued, it remains active as long as the inputsignal is faulted.

POINT I/O CounterModules

Choose the POINT I/O high-speed counters when you need:

Intelligent counter modules with their own microprocessors and I/O that arecapable of reacting to high-frequency input signals up to 1 MHz.

Signals received at the inputs are filtered, decoded, and counted.

Some modules can generate a pulse width modulated signal. (1734-VHSConly)

Count and rate values can be used to activate up to two embedded outputs in lessthan 1 ms (1734-VHSC only).

Signals are also processed to generate rate and time-between pulses (pulseinterval) data.

OFF to ON delay is time from a valid output “on” signal to output energization.

The counter modules serve as signal conditioners and function blocks (i.e., counters)between the customer process signals on the mounting base and the POINTBusbackplane containing the command information. The three main functional blocksare the customer digital I/O interface, the counter “ASIC”, and the microprocessor.

The counter modules accept feedback from:

encoders (either single-ended or differential)

pulse generators

mechanical limit switches

frequencies up to 1 MHz

25


A filter is available with four settings:

50 Hz

500 Hz

5 kHz

50 kHz

The filter can be turned off to achieve the fastest counting rate.

The input voltage range is 5V dc (1734-IJ and -VHSC5) or 15-24V dc (1734-IK and -VHSC24). The module returns the count or frequency in the form of a 24-bit binarynumber (0-16,777,215) expressed in a 32-bit word. Each counter has a user-selectable preset and rollover value associated with it.

The counter modules operate in the following modes:

counter mode - read incoming single-phase pulses, return a binary count

encoder mode - read incoming two-phase quadrature pulses, return a binary count

period/rate mode - count internal clocks during the on period, return a frequency(1734-VHSC24 and -VHSC5 outputs are updated only at the end of the period)

continuous/rate mode - count internal clocks during the on period, return afrequency (1734-VHSC24 and -VHSC5 outputs are updated continuously during thisperiod)

rate measurement mode - read pulses during the sample period, return afrequency

pulse width modulation (PWM) mode - generate a pulse width modulated signal(1734-VHSC24 and -VHSC5 only)

pulse generator mode - generates a pulse of defined width, returns width andquantity of trigger (1734-VHSC24 and -VHSC5 only)

The operation of the counter and encoder modes is nearly identical. The differencebetween the two modes is in the type of feedback (one-phase versus two-phase) forthe count direction (up or down). In encoder mode, a transition is expected on B forcounting to proceed in a direction, whereas, in counter mode, the B input may be leftat a static level. All operating modes are selected by writing appropriate configurationdata to the module.

Use the 1734-TBCJC with the 1734-IT2I thermocouple input module.

The POINT I/O system follows a “No Tools” design approach. The mounting base(1734-MB), I/O module, and Removable Terminal Block (1734-RTB) may beassembled as a system without tools. The POINT I/O mounting base, mounts directlyon the DIN-rail either vertically or horizontally.

The mounting base forms the interconnect for the POINTBus backplanecommunication and field power bus distribution. The mechanical keying of themounting base prevents incorrect module placement.

The Removable Terminal Blocks (RTBs) provide eight or twelve separate terminallocations for field wiring. They also provide vertical access to wire and screwterminations. Each terminal is numbered and a separate terminal point is providedfor each wire, including a shield ground terminal point for 2-point analog modules.

Once the RTB is wired properly, you never need to rewire terminations. These RTBsseparate independently of the base and I/O module to facilitate rapid installation andcommissioning of the system, whether it’s one loop or one sub-system at a time. Eachterminal is numbered on the bottom of the RTB to simplify troubleshooting duringcommissioning or maintenance cycles.

Expansion PowerUnit

The 1734-EP24DC expansion power unit passes 24V dc field power to the I/Omodules to the right of it. This unit extends the backplane bus power and creates anew field voltage partition segment for driving field devices for up to 17 I/O modules.The expansion power unit separates field power from I/O modules to the left of theunit, effectively providing functional and logical partitioning for:

separating field power between input and output modules.

separating field power to the analog and digital modules.

grouping modules to perform a specific task or function.

You can use multiple expansion power units with the 1734-ADN, -ADNX, ACNR, AENT,and APB communication adapters to assemble a full system. For instance, if you areusing the 1734-ADN adapter, you may use a 1734-EP24DC expansion power unit toadd additional modules. For example, if you had a 36 module system with a 1734-ADN adapter, you would have at least two or more 1734-EP24DC expansion powerunits to provide more PointBus current for modules to the right of the supply.

Field PowerDistributor

You can use the 1734-FPD field power distributor with a broad range of voltageinputs including 5V dc to 250V dc and/or 24V ac to 240V ac applications and I/Omodules.

The 1734-FPD field power distributor passes through all POINT I/O backplanesignals, but does not provide additional POINTBus backplane power. The field powerdistributor gives you the ability to change the field power distribution source for I/Omodules to the right of the 1734-FPD field power distributor. This facilitates logical orfunctional partitioning of low-channel count, high I/O-mix applications using any ofthe communication adapters.

Step 6 - Select:

Determining MountingRequirements

Placing POINT I/OModules

The producer/consumer model multicasts messages. This means that multiple nodescan consume the same data at the same time from a single device. Where you placeI/O modules in the control system determines how the modules exchange data.

For a Rockwell controller to control 1734 I/O, the I/O must be:

on the same network as the controller or

on a ControlNet network that is local to that controller or

on an EtherNet/IP network that is local to that controller

Assume that the network links in this example are either ControlNet or EtherNet/IPlinks. Both links can be the same, or one link can be a ControlNet link and the othercan be an EtherNet/IP link. Chassis A can control the 1734 I/O modules on NetworkAB, but not on network BC. The ControlLogix controller in Chassis A can only sendmessages to the POINT I/O on network BC.

38


Power Supply Distance Rating

Modules are placed to the right of the power supply. Each 1734 I/O module can beplaced in any of the slots right of the power supply until the usable backplane currentof that supply has been exhausted. An adapter provides 1A current to the POINTBus.The 1734-EP24DC provides up to 1.3A and I/O modules require from 75 mA (typicalfor the digital and analog I/O modules) up to 220 mA or more.

Mounting thePOINT I/O System

You can panel mount or DIN-rail mount a POINT I/O system. The POINT I/O systemmay be mounted in the horizontal or vertical orientation.

If you decide to use a DIN rail, use steel, 35 x 75.5 mm DIN-rails (A-B part number199-DR1; 46277-3; EN 50022). The DIN-rails for all POINT I/O system componentsmust be mounted on a common, conductive surface to ensure proper electro-magnetic interference (EMI) performance.
