Communication Modbus 2.3 Exception Responses from the Modbus Gateway Exception Responses from the Modbus Gateway If a request from the Modbus gateway cannot be forwarded to the associated Modbus slave device or the Modbus slave device does not respond, the Modbus gateway sends Modbus exception codes in exception responses messages to the Modbus TCP client. -
Page 19: Modbus Registers
The Modbus bus mapping documents for the individual SICAM devices use the register number to reference a piece of information in the Modbus register set. NOTE You find the Modbus bus mapping document (Excel table) for the SICAM Q200 devices under: http:// www.siemens.com/sicam-q200 SICAM, Multifunctional Recorder, Manual E50417-C1040-C606-A3, Edition 03.2017... - Page 20 Communication Modbus 2.4 Modbus Registers Only holding registers are used for SICAM Q200. All measured values, indications, metered values etc. are stored in these holding registers. Characterization of the register type (holding register) in the highest digit of the register number is not used in the Modbus documentation of SICAM Q200.
