C.7 CONFIGURATION DATA
To read out the stored Configuration Data the MODBUS function Read Holding Registers 03h is
used as described in [2]. To set a Configuration Data the MODBUS function Write Multiple
Registers 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.
