In the new main way scenario, general input units and power distribution units
communicate with the ECC800-Pro using the Modbus-MAC protocol. After the general
input units and power distribution units properly connect to the ECC800-Pro, the
ECC800-Pro automatically identifies the units.
Then, you need to set parameters for the general input units and power distribution units;
otherwise, a false alarm may be generated.
Set parameters for general input unit 1.
