2.0 DESCRIPTION

2.1 Operating ModesThe MIB (Multi Interface Board) provides an interfacebetween SATS air conditioning units and the StulzTeleCompTrol program or a BMS.

It takes queries and commands from the BMS andtranslates them into a format which is understood bySATS A/C unit controls.

The MIB can manage up to 32 SATS A/C units. TheSATS controller in each A/C unit is sequentiallypolled by the MIB several times a second.

Following protocols are supported:- SDC (TeleCompTrol)- MODBUS (BMS)- SNP (BMS)- P90 (BMS)

The MIB is also capable of operating a sequencingfunction with up to 32 SATS A/C units, which can bedivided into 4 zones. The sequencing functioncontains alarm monitoring and the start-up of unitswhen a limit is exceeded.

The MIB is provided in two forms:

1. Installed in the electric box of an A/C unit where itssupplied a 24 VAC voltage source from the unit.

2. Installed in a separate, wall mounted enclosurewith an internal power supply.

SNP and P90 protocols are not used inthe USA. Please disregard sections inthis manual relating to those protocols.}

2.2 Technical SpecificationsThe MIB does not have a display or keyboard and can only be configured and serviced with a BMS or a PC viaRS232 interface (COM port, service interface).The MIB can manage data from up to 32 Stulz controllers.The MIB has an independent real time clock.The software is saved in a Flash EPROM. New software can be downloaded from a notebook or PC without theneed of changing hardware.The board is operated with commands and not with menus, similar to the PC operating system DOS.LEDs show current bus activity and workload of the board.With the assistance of the available monitoring functions it is possible to observe all data in the bus and interfaces.On the BMS side various protocols and transmission options can be selected. It is possible to choose betweenan RS 232 or an RS 485 port of the MIB.

2.2 Technical Specifications (Continued)A sequencing function with up to four independent zones can be defined.Sequencing can include up to 32 units.Valid alarms can be defined for alarm monitoring.Upper and lower limits can be defined for limit value monitoring.

2.2.1 TimingA non-response-timeout programmed in the BMS (time between two requests from the BMS without an answerfrom the STULZ MIB) must be longer than 1 second.

The response time is up to 1 second depending on protocol function and the number of returned Bytes.

There is a time delay of 1 to 3 seconds after the last response from STULZ MIB before the next request by theBMS.

3.0 SERVICE INTERFACE

Since the C6000/C7000 MIB has no keyboard nodisplay the configuration and service is handled withthe service interface.

The program software is downloaded with thisinterface so it is no longer necessary to change theprogram EPROMs. The interface is a serial type(RS232-1) with a SUB-D 9 pin socket. It is markedwith X4 on the CPU board.

Actualizing the firmware and the card configurationcan be done with the C6000/C7000 MIB serviceprogram. This Windows based program gives youfollowing tools:

Software DownloadConfiguration and ServiceBMS Function Test

3.1 WiringThe service port of the MIB must be connected to afree COM port of a notebook or PC via serial cable(C6000 Service Cable).

In a notebook or PC there are two different types ofserial interface: either 9 pin SUB-D or 25 pin SUB-D.We recommend using the C6000 service cable,which has a 9-pin plug on both ends.

For PC without RS232 interface an adaptor cable toconnect the service cable to the USB port is avail-able.

4.0 THE STULZ BUS

The Stulz bus is an RS 485 bus with fixed transmis-sion parameters such as baud rate 9600 Baud, 8data bits etc.

Following values are valid for the RS 485 bus:Differential signal is transmitted via HIGH/LOWconnectionMaximum length: 3200 feet (1000m)Maximum controller distance: 114 feet (35m)Maximum number of controllers: 32Connection: 2 pole shielded data lineControllers wired in series, not in starData bus termination resistor (Z) at the beginningand end of bus

The Stulz Bus connects up to 32 Stulz units with the MIB.

All types of Stulz controllers can be connected to theStulz bus.

Stulz units are sequentially scanned by the MIB thatsaves the data, whereby the CPU address of thecontroller plays an important role. Eventual alarmsare recognized and can be transmitted to othersources. On the other end requests made by theBMS can be answered with this data or BMS com-mands are directly transferred over the Stulz bus tocontrollers. It is also possible to assign a sequencingfunction with the Stulz bus; i.e. the controller receiveson/-off commands via the Stulz bus.

4.1 WiringThe STULZ bus is a RS485 bus where up to 32 unitscan be connected with a MIB. The wiring is con-nected in series and not in parallel.

At the beginning and end of the Stulz Bus a termina-tion resistor (Z) must be placed. (See the exampleson next page.) The C6000 MIB has its own integratedtermination resistor (Z). This resistor is activated bysetting Jumper X2 to position A when the MIB is atthe beginning or end of the Stulz bus.

The Stulz bus is a two wire connection with shielding.The shield is connected on both ends to the providedterminals.

Controllers of type C5000 must be equipped with aMAX-Board.

4.1.1 The C5000 MAX BoardThe C5000 requires a MAX Board since it does notpossess its own RS485 interface.

The jumper address defines the board function:1. Normal function as C5000 Max board2. This Max board interfaces with a C4000 Relay

Board3. Reserved4. Reserved

Configuration of Terminal:1. 5V DC2. RS 485 Databus HIGH3. RS 485 Databus LOW4. 0V

The two LEDs show the following: V1 lights up when data on the RS485 bus is trans-mitted to the controller with MAX board.

V2 lights up when the controller with the MAX boardis sending data on the RS 485 bus.

C4000 controller must be of the C4000max version.

Example 1:

Example 2:

4.2 ConfigurationAll units need their own CPU address, without anyduplicates, so that they can communicate in the busline (Exception C6000 Supervisor/Controller). Theyare configured for each controller type as follows:C6000: Service / Password / Gen. Settings / Inter-faces / CPU-addr:C5000: Service / Password / Gen. Settings / Inter-faces / CPU-addr:C1002: Menu point CPU-Address chosen with arrowkeysC4000: Ring C configuration / interfaceC1010: see C1010 manualC6000 Chiller: Service/Password/Settings/System/Address

The valid range of CPU addresses is from 1 to 255.

In systems with a controller/supervisor combinationthe following must be observed:

In a C5000 supervisor/controller combination bothcontrollers receive their own address.

Both controllers can be queried separately. Since bothunits have their own sensors they receive theirsetpoints from both controllers. When the supervisordoes not control you wont receive any alarms whenquerying the supervisor.

In a C6000 Supervisor / Controller combination bothcontrollers have the same address and only the cur-rently active controller responds. You will always receiveall alarms and the correct status of the components.

For the chiller (C6000 Chiller) a configuration with asupervisor is not possible.

(February, 2007)


4-3

When the MIB is working with the SDC protocol onlyaddresses 1 to 32 can be managed.

After all controllers have received an address and theprotocol and gateway addresses have been assigned,the board must be configured.

This tells the board, which controller can currently beaccessed.

The C6000 MIB has an automatic Stulz bus unitrecognition system.

With this function all connected Stulz units are auto-matically recognized and the configuration is regis-tered.

The command for automatic recognition is: checkbus

The MIB answers with Just a moment please! andbegins querying the Stulz bus by trying to reach allcontrollers. This procedure can take up to 1 minuteand can be stopped by pressing a key.

Just a moment please!Connections will be terminated!Press key to stop.Unit 1:found (C5000) (2 mod.,Room Air)Unit 2: found (C5000) (2 mod.,Room Air)Unit 3: found (C5000) (2 mod.,Room Air)Unit 4: found (C5000) (2 mod.,Room Air)Unit 5: found (C5000) (2 mod.,Room Air)Unit 6: found (C5000) (2 mod.,Room Air)Unit 7: not present!Unit 8: found (C4000) (1 mod., Room Air)Unit 9: not present!Unit 10: found (C1002) (2 mod.,Room Air)Unit 11: found (C1002) (2 mod.,Room Air)Unit 12: found (C1002) (1 mod., Room Air)

During the Stulz bus (RS485) check, all functionsand procedures are interrupted

The current configuration of the Stulz bus can bedisplayed with following command: bus

Controller 01:C5000 (2 Mod.,Room Air) = 100%






Controller 07: (0 Mod.,Room Air) = 000%


Controller 09: (0 Mod.,Room Air) = 000%Controller 10:C1002 (2 Mod.,Room Air) = 100%























STULZ-Bus monitoring: onBus-scan speed: 3

(February, 2007)


4-4

When a controller is not recognized correctly, there isstill the possibility to manually configure the unit.The following command is used:confbus

Examples:To configure address 15 with a C5000 in a 2 Moduleunit and supply air control: confbus 15 c5000 2 s

To configure address 4 with a C1002 in a 1 Moduleunit and return air control: confbus 4 c1002 1 r

To configure address 17 with a C1010 in a 1 Moduleunit and return air control: confbus 17 c1010 1 r

To configure address 13 with a C4000 in a two Moduleunit and supply air control: confbus 13 c4000 2 s

To erase a controller at address 7, enter the following: confbus 7 -

All entries can be viewed with the bus command.

The units found status must be at 100% after oneminute.

4.3 TroubleshootingAfter a few minutes the accessibility of all unitsshould be at 100%. When the accessibility is 0%, thiscan have two reasons:

1. The wiring does not correspond to the schemeshown in chapter 4.1, perhaps hi and low areswitched or the termination resistor z is missing.

2. A unit connected to the Stulz bus is malfunctioningor blocking the complete data transfer on the Stulzbus.

In order to localize the error please remove all unitsfrom the Stulz bus and try to activate communicationwith only one unit by entering the command bus incertain time intervals.

The accessibility of this one unit must increase withtime to 100%.

Now try connecting one unit after the other followingthe same procedure while observing the accessibilityof the connected units with the bus command.

When the accessibility of a newly connected unitdecreases, then this unit is the one causing theproblem. In this case the socketed driver 75176 mustbe exchanged. When the control unit causingproblems is a C5000, then possibly the completeMAX-board must be exchanged.

4.3.1 STULZ BusData transferred on the Stulz bus may be monitored.

In order to slow the flood of data on the Stulz busenter the command:busspeed 1

This command selects the query speed on the Stulzbus, and slows the transfer rate (1=slow, 2=medium,3=fast)

Data is displayed with following command:stulzmon on

The display function is turned off with this command:stulzmon off

or simply x to turn off monitoring functions.

An s behind the bytes stands for sending (the bytes that are sent by the MIB on the Stulz bus), the sum ofwhich represents a query.

An r stands for receiving noting the bytes received by the MIB, which is the answer of the Stulz controllers.

The first query of the MIB is as follows: 01s 01s 02s FCs FFs

The most important part is only the first two bytes (01, 01).

The first byte (01) represents the CPU address of the queried controller; in this case the controller with CPUaddress 1 is queried.

Data is displayed in hexadecimal form:

(February, 2007)


4-6

Since the numbers are displayed in hexadecimal form, the result is following address allocation:

Hex Decimal Hex Decimal01 01 11 1702 02 12 1803 03 13 1904 04 14 2005 05 15 2106 06 16 2207 07 17 2308 08 18 2409 09 19 250A 10 1A 260B 11 1B 270C 12 1C 280D 13 1D 290E 14 1E 300F 15 1F 3110 16 20 32

The second byte (also 01) shows the type of query and must be either a 01 or a 21. When this isnt the caseyou can ignore the query.

05r 0Fr 00r 00r 00r DFr F1r

Here only the first address is important showing the CPU address of the answering controller (01). The totalanswer of the controller is either, 140 bytes long when the type of query is 1 or 232 bytes long when the type ofquery is 21.

From this scenario it is easy to see which controllers are queried by the MIB and how they respond.

When a controller is not responding then it is not configured with checkbus/confbus.When a controller does not respond or gives a false response (answer too short), then the wiring is incorrectWhen none of the controllers respond, refer to chapter 4.3 trouble shooting.

In order to set up the connection to a BMS or TeleCompTrol following six parameters must be set the same forMIB and BMS, as shown in the examples below. The parameters differ with the type of BMS; the BMS pro-vider must supply these.

1. Port Selection: port rs485 (Use of RS 485-2 ports for BMS/TeleCompTrol) port rs232 (Use of RS 232-2 interface for BMS/TeleCompTrol)

2. Baud rate: baud 9600 (Baud rate is set to 9600 Baud, possible values: 57600, 56000, 38400, 19200, 9600, 7200, 4800, 3600, 2400, 1200, 600, 300)

3. Number of Data Bits: databits 8 (Transmission with 8 data bits, possible values: 5, 6, 7, 8)

5.1.2 Connection of BMS/TeleCompTrol Program via RS 232-2 Interface

Up to 32 Stulz units:C1002

C1010 with SERC1010C4000maxC5000 with MAXC6000/C7000

5-3

4. Number Stopbits: stopbits 1 (Transmission with 1 stop bit, possible values: 1, 2)

5. Choice of Parity: parity none (Transfer without parity, possible values: none, even, uneven)

6. Flow Control Selection: flowcon off (Flow control is off, possible values: off, on)

5.2 MODBUS Protocol

Selection of protocol: protocol modbus

An interface to MODBUS can be done via the RS 232-2 port or RS485-2 port.Up to 8 MIBs can be queried in parallel via the 485 BMS port. Since every MIB manages up to 32 controllers, itis possible to scan 8 MIB x 32 Stulz controllers with one 485 BMS port.It is only necessary to assign different gateway addresses to each MIB.

The command gateway 2 assigns the board to gateway address 2

The list of managed Stulz controllers is shifted with the gateway address as follows:

Gateway Address of the MIB Addresses of the Managed Stulz Units0 1 ... 321 33 ... 642 65 ... 963 97 ... 1284 129 ... 1605 161 ... 1926 193 ... 2247 225 ... 255

Example: Units, which are connected to a MIB with gateway address 2, must have an address in the range from65 to 96 (see chapter 4.2 Stulz bus configuration).

The analogue values e.g. for temperatures are transmitted in IEEE754 32 Bit format. A MODBUS register has awidth of 16 bit, i.e. two MODBUS data point addresses are assigned by each analogue data point.

Sign Exponent Mantissa

Bit # 31 30 - 24 23 22 - 16 15 - 8 7 - 0

Byte # 3 2 1 0

Lower ModBus-address = high order word of IEEE-valueHigher ModBus-address = low order word of IEEE-value

The real value will be calculated as follows:

[(mantissa / 223) + 1] x (2 (exponent - 127) ) x (-1) sign

The command ieee is used to change the order of a transmitted word.

ieee msb (Higher word order of IEEE is transmitted first; Byte # 3, 2, 1, 0)ieee lsb (Lower order word of IEEE is transmitted first; Byte # 1, 0, 3, 2)

Here it is also required to consult the BMS provider.

5.4 Connecting the TeleCompTrolProgram

5.4.1 Choosing the Protocol protocol sdc

The connection of the TeleCompTrol Program canfollow in three different ways:

5.4.1.1 Direct connection via RS232 interfaceA serial cable (e.g. C6000 service cable) is con-nected from an unused COM port of the PC to theRS232-2 interface of the MIB.

With this method only one MIB can be connected tomanage up to 32 controllers.

The maximum length of the serial cable should notexceed 32 feet.

5.4.1.2 Direct connection via RS485 BusSince a standard serial cable does not have a RS485 port, either a RS485 board must be installed oran unused COM port of the PC must be connected toa RS232 RS 485 converter.

With this method it is possible to connect up to 32MIBs giving a total of 32x32 = 1024 Stulz controllers.

5.4.1.3 Modem ConnectionAn unused COM port of the PC is connected to themodem with a serial cable.

With this method it is possible to call MIBs all overthe world.

The identification is accomplished with a SDC ID anda password which must be entered correctly in thePC and the MIB.

Setting Telephone Number 1 for Alarm Transfer tel1 T0,(xxx)xxx-xxxx

This is the telephone number of the modem con-nected to a running TeleCompTrol program. Thetelephone number 1 will be called 3 times when thealarm transfer fails. After that telephone number 2will be dialed. The dial attempts will follow everyother minute.

Setting Telephone Number 2 for Alarm Transfer tel2 T0,(xxx)xxx-xxxx

This is the telephone number of the modem con-nected to a running TeleCompTrol program. Thetelephone number 2 will be called 20 times when thealarm transfer fails. After that the alarm transfer willbe stopped. The dial attempts will follow every otherminute.

5.4.5 Configurations of TeleCompTrolProgram

5.4.5.1 Channel Selection

Alarm ChannelHere the COM port must be chosen for the modemconnected to receive incoming alarms. The tele-phone number of this modem is set on the MIB withboth tel1 and tel2 and will be called in case ofan alarm.

Modem Connection (Scan./Conn.)The COM port to which a modem is connected mustbe chosen here in order to communicate with theprogram via MIB.In case of a direct connection this channel must bedeactivated.

Bus Connection (Direct Connection)The COM port which is directly connected to the MIBis selected here. In this case it doesnt matter if onlyone MIB is directly connected to the COM port or ifup to 32 MIBs are connected with aid of a RS485board or converter.In case of a modem connection this channel must bedeactivated.

Configure Alarm ChannelSet the baud rate to 9600Baud and choose thedialing method

Configure Scan ChannelSet the baud rate to 9600Baud and choose thedialing method

Configure Unit GroupA unit group is defined by a MIB and the unitsconnected to it.Define a unit group and give it a name.The SDC-ID must be identical to the SDC address ofthe corresponding MIB.The password must be identical to the SDC addressof the corresponding MIB.The number of unit is equal to the units connected tothe MIB.When the connection type is modem and not directthen modem connection must be selected. In thiscase the telephone number of the modem must alsobe entered.

With this configuration it is possible to achieveconnection to a group of units. For further informa-tion on TeleCompTrol, please refer to the ManualIndex 62A: TeleCompTrol.

5.5 TroubleshootingWhen it is not possible to establish connection to aBMS or TeleComptrol, there are two possible reasons:

1. The data link to the Stulz controllers is notworking (Stulz Bus).

2. The data link to the BMS/TeleComptrol is notworking.

This trouble-shooting guide proceeds on the premisethat a working data link always consists of a query anda response to the query. The MIB offers the tool todisplay data both on the Stulz bus as well as from theside of BMS/TeleCompTrol.

5.5.1 BMS ConnectionThere are three modes of displaying data on the BMSside:

1. Hexadecimal Display bmsmon hex2. Decimal Display bmsmon on3. ASCII Display bmsmon ascii

The following commands turn off the display mode: bmsmon offor simply x to turn off all monitoring functions.

Here is a sample of a BMS query in hexadecimal formin the MODBUS protocol:

03r 01r 00r 00r 00r 01r FCr 28r

03s 01s 01s 01s 91s F0s

Bytes marked with r at the end are received by theMIB from the BMS, so they represent the request fromthe BMS. Bytes marked with s at the end are sent asan answer by the MIB.

Since it would go beyond the scope of this manual todescribe every protocol in detail, only the followingconsiderations shall suffice:

1. Are queries from the BMS reaching the MIB?2. When queries are indeed being forwarded, is

the MIB responding or is it possible that thewrong protocol is being used?

If BMS request and MIB responses are displayedand despite this no correct display on the BMS canbe established, you can only record the data via theterminal program.

Please send this record to SATS Product SupportGroup.

6.0 THE SEQUENCING FUNCTION

Sequencing can be divided in up to four zones andworks on the basis of a correctly set-up and wiredStulz bus.

The maximum number of controllers, which can beconnected is 32. These 32 controllers can be distrib-uted on the 4 zones or all the controllers may beassigned to one zone. Each zone may contain eitherair conditioning units or chiller units. For the se-quencing of chillers, the unit passwords must bestored in the MIB (with the command unit password).

It is not possible to configure a single controller twicee.g. for different zones.

Limit values can be defined per zone. In case a limitis exceeded in the top or bottom range, all controllersof a zone will be started. For this scenario it ispossible to define valid alarms which will start astand-by unit of a zone when the alarm occurs.

6.1 Technical SpecificationThe sequencing function has priority over BMScommands. This means that its not possible to start/stop a unit via BMS when the same unit is connectedto sequencing.

A maximum of 4 zones can be configured.

A maximum of 32 controllers can be connected.(Stand-by or active)

The controllers are addressed by their individualCPU address.

The sequential turnover can be set for an hourlybasis.

Test sequencing can be defined for a five-minuteperiod.

The turnover time is valid for all zones.

When a stand-by controller is activated due to a limitalarm, the normal sequencing function of a zone isinterrupted but the sequencing timer continues.

6.1.1 Alarm Supervising FunctionAn alarm filter (which also observes manual off), canbe used to define valid alarms.

A controller that cannot be reached is always a validalarm.

The valid alarms are separately adjustable for eachzone.

When a valid alarm is detected from a controller in azone, this controller is turned off until the alarm isreset. The controller can then be started again.

For each controller that is turned off, the first stand-by controller in the zone is started and runs until thealarmed controller is back online. For every defec-tive controller, one stand-by will be started if avail-able.

When a stand-by controller also receives an alarm, itwill not be turned off.


(February, 2007)


6-2

6.1.2 Limit Supervising FunctionIn order to find the current value, all controllers of azone are queried. A mean value from all measuredtemperature and humidity data is then used.

There is an upper and lower limit value for tempera-ture and humidity. The limit must be exceeded for atleast 30 seconds.

All stand-by controllers are started when the limit isexceeded. After 10 minutes it is checked if the limitvalues are still being exceeded. When this is thecase, the stand-by units will continue to run. subse-quent checks follow every 10 minutes, until thevalues are in a safe region.


6.1.3 Emergency OperationWith parameter emernum you can choose thenumber of defective units which will cause thesystem to switch over to emergency operation.

In the case of emergency operation all stand-by unitsare started. The temperature selected with theparameter emertemp is used for the new tempera-ture set point and transmitted to all units.

Once the value selected with parameter emernumis reached, the system stops the emergency opera-tion.

The active or stand-by status is passed on in clockwise rotation during every sequencing turnover period.

7.2 STULZ - Bus Commandsbus Shows the status of the Stulz-Bus.

It shows which unit can be accessed under whichaddress (CPU-Address), how many modules areconnected and how it is controlled. By the controlmode you can see whether the unit is a chiller or anair conditioning unit. The more detailed significationis described in the online help.

The accessibility should reach 100% after a fewminutes. If some units respond poorly or give noresponse at all, the accessibility can drop below 100%.In this case the wiring of the bus must be checked. It isalso likely that the termination resistors are missing orthat a MAX-board is malfunctioning.

Stulz-bus monitoring can be started with the commandstulzmon on. The query speed on the Stulz busshould be reduced with the command busspeed 1to get a better overview of the vast amount of incom-ing data.

This is an example for the connection to a BMS withMODBUS protocol.In the following each individual command is explained:port rs485 Defines the communication port as

RS485 II for BMS or TeleCompTrol.port rs232 Defines the communication port as

RS232 for BMS or TeleCompTrol.Can be checked by entering bms.

address 1 Setting of SDC-ID or address of MIB.When connecting the TeleCompTrol, the address mustcorrespond with the one used as SDC-ID. The SDC-IDmust be between 1 and 59.999.Can be checked by entering bms.

gateway 0 This command is only used whenMODBUS or SNP protocol is selected. In theseprotocols there arent any SDC-IDs this is why thecontroller changes the regular 1 to 32 addresses:gateway 0 Address of the controllers from 1 to 32gateway 1 Address of the controllers from 33 to 64gateway 2 Address of the controllers from 65 to 96gateway 3 Address of the controllers from 97 to 128gateway 4 Address of the controllers from 129 to 160gateway 5 Address of the controllers from 161 to 192gateway 6 Address of the controllers from 193 to 224gateway 7 Address of the controllers from 225 to 255

When a gateway is changed this will affect all Stulz-bus commands e.g. bus. The controllers CPU ad-dresses must also be changed accordingly.See also chapter 4.2, STULZ Bus configuration.Control: bms.Ieee msb Byte order for IEEE format = msb.Ieee lsb Byte order for IEEE format = lsb.This command only has a meaning for the MODBUSprotocol.

8.0 THE C7000 MIB SERVICEPROGRAM

The service program is Windows based and requiresWindows 95 or later.It is installed with a set-up program and consists ofthree parts:

setup.exe mib.CAB setup.lst

When the program is on a diskette the CAB file issplit into numerous files.All data is copied into a register and then setup.execan be started. After successful installation theprogram can be started under the Windows buttonsStart/Programs/mib7000

After starting, following screen will appear:

The program itself is split into three sections:

Software download- With this function new softwarecan be downloaded onto the MIB.

Terminal- A Terminal program used to configure theMIB

BMS Function Test- Testing by simulating a BMS.This means that commands can be sent to a MIB,whereby the sent and responded bytes of the protocolare displayed.

(February, 2007)

8.1 Software DownloadWith this function new software can be downloaded tothe MIB.This software is always a *.h86 file (Intel HEX Files).

After wiring is completed, (Chapter 3.1) and the MIB isplaced in download mode, (Chapter 3.2) the softwarecan be downloaded as follows:1. Turn off the MIB, (disconnect from power supply).2. Place jumper X6 on the board of the MIB to position

A, (download mode).

3. Remove the jumper X13 on the MIB board. (Thisway the watchdog timer is disabled).

4. Connect the service interface to a notebook/PC, seeChapter 3.1 wiring

5. Turn on the board; it is now in download mode.6. Start the MIB service program and select the COM

port connected to the MIB in the software downloadfield.

7.Select the transfer rate (e.g.38400 Baud)8. Click on the software download button and following

screen will appear:

Select the drive and register in the top right frame and choose the *.h86 file to be transferredClick on data transferData transfer can take some time. The status bar in the bottom right corner shows the transfer progression.When the transfer is completed without error, following screen should appear:

If an error occurs during transfer, the MIB must be turned off and then on again. This will allow the transfer tocommence again. In this case it may help to also select a lower baud rate.When a transfer is successful the board must be turned off (remove power supply).1. Place jumper X6 to position B on the board (operation mode).2. Place the jumper X13 on the MIB board. (This way the watchdog timer is enabled).3. Turn on the board.The board is working correctly when the single green LED is blinking.

8.3 BMS Function TestA BMS can be simulated with this function.All controllers can be queried, turned on/off etc. just like with a BMS.Both the PCs requests and MIBs answers are displayed.

Select the correct COM portWhen you are using the RS232-2 interface of the MIB, the board must be set to port rs232 beforehand.When you are using the RS485 interface of the MIB, the board must be set to port rs485 beforehand.Select the correct protocol and transfer parameters (Baud rate etc.)

Click the BMS function test button and the following will be displayed depending upon the selected protocol:

(February, 2007)


8-6

The controller ID defines the CPU address of the controller you are querying.The Close button ends the simulation and closes the window.

You can see the request of the PC: 01s 01s 00s 00s 00s 01s FDs CAsAnd the MIBs response: 01r 01r 01r 01r 90r 48r

The program automatically evaluates the response and shows:Number of Bytes: OKCheck Sum: OK

Controller 1 is thus accessible by the MIB running with the MODBUS protocol.

The Clear Display button deletes the output in the text window.
