General information Communication is a very wide topic. From the ComAp control systems user point of view we have to distinguish at least following levels of communication:

Communication between controller and peripherals, between controllers Communication between controller InteliGen (IG-CU), InteliSys (IS-CU) and its peripherals (such as IG-IOM, IS-AIN8) is described in the controller Users guides. Communication between controllers for multiple applications is also described in the Users guide. For IG-CU:

IG-MEXT-MEXT+IOM-x.y.PDF, IG-MINT-MINT+IOM-x.y.PDF, IG-SPM-SPM+IOM-x.y.PDF, IG-SPtM-SPtM+IOM-x.y.PDF, IG-SSB-SSB+IOM-x.y.PDF.

eg. in chapter Extension modules (CAN bus) connection. For IS-CU of:

IS-MINT-MINT+x.y.PDF, IS-SPI-SPI+x.y.PDF , IS-SPM-SPM+x.y.PDF, IS-SPtM-SPtM+x.y.PDF, IS-SSB-SSB+x.y.PDF.

eg. in chapter External modules connection. Communication features of InteliLite controllers please refer in IL-AMF-x.y.pdf IL-MRS-x.y.pdf LiteEdit-x.y.pdf

Communication between controller(s) and superior, service or monitoring system (usually PC) Communication between controller(s) and superior, service or monitoring system (usually PC) is described in this Communication guide. There are following types of communication between controller(s) and superior system: - Local Connection - Remote Connection - Modem Connection - Modem Callback - Internet Ethernet Connection - Internet Dialup Connection (Internet Callback) - Active Call - Active SMS - Active e-mail - SMS Message Control - Terminal connection There is following communication option available for the user SW designers and third party software: - Modbus Connection


How to use different characters sets

The first step Characters set is fix programmed in IG controller display (OTP) processor and cant be changed. To find out supported characters set please check IG controller serial number according following table. Serial number is visible on IG info screen which is activated by pressing and holding of ENTER button and pressing of PAGE button. Serial number Character set support xx1xxxxx Standard character set: part of ASCII code (less than 128) xx2xxxxx Standard character set + West European languages (German, French,

Dutch, Swedish, Finnish, Spanish, ..) xx3xxxxx Standard character set: + Chinese characters xx4xxxxx Standard character set: + East European languages (Czech, Polish,

Russian, ) xx5xxxxx Standard character set + Turkey characters

The second step Open the WinEdit Translator. Create New dictionary (Dictionary New dictionary), Select source and Target language. Select Font and script for Translated text according to IG display version. Translate texts to selected language. Close dictionary, Write archive to IG.

RS232 cable It is recommended to use standard Null-modem cable for local connection between controller and PC, although the three wires (TxD, RxD, GND) RS 232 connection is enough for direct IG-CU to PC communication:

Controller connector D-SUB9 female

PC RS 232 connector D-SUB9 female

2 ------------------------- 3 TxD 3 ------------------------- 2 RxD 5 ------------------------- 5 GND

Local connection for multiple applications

InteliGen and InteliSys CAN bus connection For InteliGen multiple applications (MINT, MEXT) connect IG-COM module to each IG-CU and

connect CAN bus to IG-MU unit. CAN bus terminals on IS-CU are active all the time, not depend on Dongle.

RS 232

iG-COM

iG-IOM iG-IOM

iG-COM

CAN

CAN 2 CAN 2

iG_MURS232

RS422 PC

There are two separate CAN bus lines on controller. One for connection between controllers, the second one (CAN2) is for external IG-IOM, IGS-PTM or IGL-RA15 modules connection. Hint: The different module ID-COM is used for InteliDrive CAN bus wiring.

I-CR module for CAN bus extension If the distance between units is too high to fit into the 200 m limit (or 900 m for 8 controllers), CAN repeater module (I-CR) can be used to extend it. Typical case in line extension: total bus length up to 400 m 32C mode

total segment length up to 200 m total segment length up to 200 m

IG (1) IG (32) IG (2) IG(x+1)IG (x)

I-CR A CAN B


Connection of IG-MU, combination of different CAN bus speeds:

total segment length up to 900 m total segment length up to 200 m

IG (1) IM (8) IG (x) IG-MU

I-CR A CAN B

This connection allows PC communication to all controllers in the system (e.g. via MultiEdit), including a distant InteliMains unit.

I-CR module functions: - Intercontroller CAN bus extension (one or more I-CR modules can be used). - Intercontroller CAN bus bus-tie bridging makes groups of controllers in segments A and B invisible

one for another depending on bus-tie breaker state, keeping the PC communication (IG-MU, IG-IB) in function for all controllers.

- Peripheral CAN bus extension

I-CR configuration jumpers: P2 Forces 250 kbps mode (32C) on CAN A, otherwise speed autodetection is used. P3 Forces 250 kbps mode (32C) on CAN B, otherwise speed autodetection is used. P4 Activates Filter mode (bus-tie bridging). P5 Forces alternate controller address 3 for bus-tie status reading (default controller address is 4). P10 If H network configuration used (two I-CR units), it must be switched to RS-422 mode.

I-CR indication and diagnostic LEDs:

LED State Function Lights Firmware is OK and running RUN Flashes Firmware corrupted (periodic Watchdog reset) Lights CAN A communication is running DET-A Flashes CAN A communication speed autodetection is in progress (I-CR

automatically enters this mode if no CAN message received for 2 s) Lights CAN B communication is running DET-B Flashes CAN B communication speed autodetection is in progress (I-CR

automatically enters this mode if no CAN message received for 2 s) CAN-A (TxC, RxC) Flashes CAN A interface activity CAN-B (TxC, RxC) Flashes CAN B interface activity COM (TxD, RxD) Flashes RS232/422 interface activity

For more detailed information about I-CR, see the Application sheet Extending the CAN bus.


Two IG-MU on CAN bus Connecting of 2 IG-MU units on one CAN bus is allowed only if each one has different CAN address. IG-MU address can be changed by internal Address 2 jumper. No jumper: IG-MU Address =1; with jumper: IG-MU Address = 2. Two PC with local (direct) MultiEdit connection at once are in following example:

RS 485/422 communication line has to be terminated by 120 ohms resistors on both end, IG-MU has integrated this resistor follow RS 485/422 converter user manual. Multiple controllers wiring with RS485/422 see in Modbus connection chapter. IG-MU unit must be switched to RS485/422 mode for remote direct connection by internal switch. Hint: When will be used ADAM module then connect Rx, Tx-A to DATA+ and Rx, Tx-B to DATA-. Shielding connect to ADAM GND on both sides and external 120ohm resistor between DATA+ and DATA- on ADAM side (in off state). Internal ADAM 4520 switches: set Data format 10 bit and baud rate 19200. Cable must be not crossed (RxD-TxD) RS232 for connection to between ADAM and PC SUB9 RS232 connector wiring: 2 - 2, 3 3, 5 5, 7 7.

RS 422/485 communication line has to be terminated by 120 ohms resistors on both end follow converter user manual. RS 485 communication can be used for more controller monitoring and controlling via WinEdit or MultiEdit. Power management function is not available when IG-COM units are not connected.

Modbus communication via IG-MU Modbus communication is available from IG-MU of sw version 1.9 Before IG-MU Modbus communication connect Modbus jumper in IG-MU unit.


Modbus protocol description Introduction Direct connection: RS232, RS422, RS485 Modem connection 9600 bps, 19200 bps (ID-only), 38400 bps(ID-only), 8 data bits, 1 stop bit, no parity Transfer mode RTU Function 3 (Read Multiply Registers) Function 6 (Write Single Register) Function 16 (Write Multiply Registers) The response to an incoming message is sent with minimum 4.096 ms delay after message reception The complete description of Modbus communication protocol can be found in Modbus Protocol Reference Guide PI-MBUS-300 and Open Modbus Specification Release 1.0. Both documents are available from web.

Communication object vs. Register All the data intended for communication has its representation as communication objects in the controller. The communication object is represented by the n-byte array in the controller memory and identified by the unique 16-bit communication object number. The register, according to Modbus communication protocol, represents a two-byte data and in communication functions is referenced by 16-bit register address. Further in the description of communication functions the communication object number will always be used as a register address and length of the communication object will be expressed by number of registers. Just one communication object can be read or written by one communication function.

Data reading The function Read Multiply Registers has to be used for data reading. The terminal sends a query and from the controller receives either the normal response containing the requested data or the exceptional response indicating a read error. Version of MODBUS Inteli implementation: 1.3, 16.9.2004 Query: Byte Meaning Note 0 Controller address 1 to 32 1 3 Function code 2 3

Check field calculation The check field allows the receiver to check the validity of the message. The check field value is the Cyclical Redundancy Check (CRC) based on the polynomial x16+x15+x2+1. CRC is counted from all message bytes preceding the check field. The algorithm of CRC calculation is introduced below on an example of a C language function. unsigned short count_CRC(unsigned char *addr, int num) { unsigned short CRC = 0xFFFF; int i; while (num--) { CRC ^= *addr++; for (i = 0; i < 8; i++) { if (CRC & 1) { CRC >>= 1; CRC ^= 0xA001; } else { CRC >>= 1; } } } return CRC; }

List of communication objects Communication objects can be splitted into two groups:


1. Communication objects dependent on the application type (SSB, SPM, SPtM, MEXT, MINT, ). Their list is stated in the Controller user guide in the section Value and setpoints codes.

2. Communication objects independent on the application type. The description of these communication objects follows.

Communication status Communication object number: 24571 Operation: Read only Data type: Binary32 Meaning: Bit 0 Reserve (= 0).

Bit 1 Invalid controller software (based on CRC). Bit 2 Invalid controller configuration (based on CRC). Bit 3 In the event history is present at least one unread record. Bit 4 P type parameters are invalid.

P type parameters are representing the controller setpoints. Values of these parameters can be set from connected terminals. If these parameters are invalid, the application functions are blocked. Parameters recovery is needed.

Bit 5 R type parameters are invalid. R type parameters are representing the data, that is only initialized from connected terminals, but its updating is made by the controller itself (e.g. statistic or time and date). If these parameters are invalid, their change from the controller is blocked. Parameters recovery is needed.

Bit 6 The event history was cleared. Bit 7 The event history was filled up at least once. Bit 8 P type parameter change occured. Bit 9 R type parameter change occured. Bit 10 Controller type see table below. Bit 11 Alarm list not empty. Bit 12 Alarm list change. Bit 13 New item added into alarm list. Bit 14 Internal controller terminal is locked up for parameter change. Bit 15 Invalid configuration format. Bit 16 Diagnostic codes change. Bits 20-17 Reserve (= 0) Bits 22-21 Password level for Setpoints and Commands write. Bit 23 Controller was initiated. Bits 28-24 Communication module version. Bits 29 Remote terminal is connected.

of the access code is conditioned by the write password knowledge.

Active call termination Communication object number: 24540 Operation: Write only Data type:

Unsigned8 Meaning: The controller can under certain conditions (e.g. after engine shutdown) establish a connection with a remote

terminal perform an active call. The remote terminal can after that (without access code knowledge) read the data needed for the analysis of the issued situation. The data transfer has to be terminated by the terminal by writing this communication object. After a successful transfer it writes the value 1, otherwise 0. If a new active call request comes up during the data transfer, the controller doesnt return the normal response, but the exceptional one (communication object 24523 has the value 237.0.0.8 - See Error list). In this case the controller doesnt terminate the connection, but it awaits the request from the terminal.

Bity23-19 Error meaning - FMI code.


Bity30-24 Number of Error occurrences. Bit31 Indication of not confirmed fail. Bity39-32 Do not use (ComAp internal). Bit40 Item validity; the first (= 0) means end of the list. Bit41 Item was confirmed. Bity47-42 Rezerva (= 0)

Error list If the controller encounters an error when processing the query, it returns the exceptional response instead of the normal one to the terminal. An exception has always the value 2 (Illegal Data Address). After receiving the exceptional response, the terminal should read the communication object 24523 containing the last error specification. The meaning of an error can be found out from the following table. MSB1 LSB1 MSB2 LSB2 Meaning 0 0 0 0 No error. 0 0 2 6 Comm. object nonexistent. 0 0 1 6 Illegal access:

Read (write) of the comm. object intended only for write (read). 253 0 0 8 No more unread records in event history. 252 0 0 8 Parameter not defined in controller configuration. 251 0 0 8 Bad write data length. 250 0 0 8 Invalid password. 247 0 0 8 Invalid controller configuration. 240 0 0 8 Operation cannot be performed now, the terminal has to repeat the request.

This error can occur when an operation with EEPROM memory (parameter write, history record read) is required at the same time while an internal EEPROM write cycle takes place.

238 0 0 8 Write cannot be performed power supply failure detected. 237 0 0 8 Another active call request is present.

This error code can be returned by the controller as the response to the comm. object 24540 write active call termination.

235 0 0 8 This error is reported by iG-MU module (Modem Bridge) in the case of a connection failure between the module and the addressed controller. The terminal can evaluate this error as a communication timeout with the controller.

234 0 0 8 Write cannot be performed periphery not responding. 233 0 0 8 Write cannot be performed parameter nonexistent in any periphery. 232 0 0 8 Bad access code for communication from a remote terminal. 231 0 0 8 Invalid controller address: value out of range 1 to 32 or already used. This

error is a reaction on comm. object 24537 write. 229 0 0 8 Undefined action. A reaction on comm. object 24521 write. 228 0 0 8 Action (although defined) cannot be performed. A reaction on comm. object

24521 write. 227 0 0 8 Written object value is not acceptable.

How create actual Communication object list For Inteligen and InteliSys controller use WinEdit menu command Controller Generate Cfg Image There are two ways to create Object list ( see Appendix 1) For InteliLite and InteliDrive controller communication objects specification use command Data export.


Modbus communication examples

Battery voltage reading Request: 0103201500019E0E (in HEX) 01 = Controller address 03 = Modbus function number (reading) 2015 = 2015 HEX = 8213 DEC = object number for Battery voltage 0001 = Communicastion object length expressed by the number of registers 9E0E = CRC (see Check field calculation) See chapter Data reading . Example: 8123 = Battery voltage, In Tab. 3 Values III is Type=Integer and Len=2byte, that means data type Integer16. See table Data types (it is conversion between IG a Modbus registers): Number of (Modbus) registers for Integer16 = 1, that means 0001. Response 01 03 02 00F9 7806 (in HEX) 01 = Controller address 03 = The same as in query 02 = Length of read data in bytes 00F9 = object data value =249 in decimal, but 8213 object is defined with one decimal point, see Tab. 3 (p.21). So real interpretation is 24,9 V (volts) because Dim (=dimension) of 8213 is V see Tab. 3 (p.21). The last part 7806 is CRC.
