    1 Introduction 1.2 Typographical conventions 1.2.1 Warning signs The signs for Danger and Warning are used in this Manual under the following conditions: Danger This symbol may be used when there may be danger to personnel if the instructions are disregarded or not followed accurately! Warning This symbol is used when there may be damage to...

  • Page 7: Protocol Description

    2 Protocol description 2.1 Master-slave principle The communication between a PC (master) and an instrument (slave) using MODbus /Jbus takes place according to the master-slave princi- ple in the form of a data request/instruction - response. Master Slave 1 Slave 2 Slave n The master controls the data exchange, the slaves only have response function.

  • Page 8: Instrument Address

    2 Protocol description 2.3 Instrument address The addresses of the slaves can be set from to 31. The instrument ad- dress 0 is reserved. The RS422/485 interface can access a maximum of 254 slaves. There are two distinct types of data exchange: Query Data request/instruction from the master to a slave, via the correspond- ing address.

  • Page 10: Timing Of A Data Request

    2 Protocol description 2.4.1 Timing of a data request Timing A data request runs according to the following timing scheme: scheme Data request Data request Master Datenanfrage Datenanfrage Response Slave Antwort End marker = 3 characters (the time depends on the baud rate) This time depends on the internal processing.

  • Page 11: Communication During The Internal Processing Time Of The Slave

    2 Protocol description 2.4.2 Communication during the internal processing time of the slave The master must not make any data requests during the internal processing time of the slave. Any data requests that are made during this time will be ignored by the slave. 2.4.3 Communication during the response time of the slave The master must not make any data requests during the response time of the slave.

  • Page 13: Checksum (Crc16)

    2 Protocol description 2.7 Checksum (CRC16) The checksum (CRC16) serves to recognize transmission errors. If an error is identified during processing, the appropriate instrument will not respond. Calculation CRC = 0xFFFF method CRC = CRC XOR ByteOfMessage For (1 to 8) CRC = SHR(CRC) if (flag shifted right = 1) then...
