If Modbus Master function is required extension module I-CB/Modbus connected via CAN1 can be
used. For more information on how to use this module please refer to InteliGen/InteliSys

Users can define Modbus registers from 42873 to 43000. Values, setpoints and Alarm states can be
specified for these new Modbus registers to prepare the Modbus protocol for batch reading and writing
or to standardize Modbus protocol between FW versions or branches.
