C.7.3 GET MODBUS DEVICE ID (03H, C001H)
This service read out the MODBUS Device ID which will be used after next system start. The
configuration will be stored at EEPROM.

C.8 ROUTINE CONTROL
To start a Routine the MODBUS function Write Multiple Register 10h is used as described in [2]. In
contrast to this specification, the Starting Address is not used as a physical address, but more as a
Service ID.
The CIMS Sensor supports only access to one Service ID (Address) at one request.
C.8.1 POSSIBLE ERROR MESSAGES
Error CIMS -> MASTER
Byte Contents Value
0 Slave Address A2h
1 Error Function Code (Function Code + 80h) FC+80h

Exception Code
0x03 - Illegal Data Value - If the range of data not correct.
0x04 - Slave Device Failure - If the syntax of the request is wrong.

C.8.2 SENSOR RESET (10H, F000H)
The routine Sensor Reset performs a reset of the microcontroller. Please pay attention that the
sensor starts in the Bootloader after the response.
