7.2 Requesting the response values of an RCMS470-12
A Modbus RTU Master is to query the defined response values of all 12 channels (BMS in-
struction code 30) 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:
