7.4 Requesting the correction factor for CT of an RCMS470-12
A Modbus RTU Master is to query the defined correction factor of all 12 channels (BMS in-
struct. code 35) for the transformation ratio of a CT from an RCMS470-12 with BMS address 5.
The Configuration register must be written as follows:
In this example, the Read register provides the following information:
