HINT
Controller sends Distributed Binary Outputs each 100ms if there are any changes in any bit position. If
there are no changes, controller sends the information with period 1s.
NOTE:
DISTBIN and DISTBOUT function is not available for IM-NT-GC controller.
7.17 Modbus Reading and Writing
Controller supports Modbus Slave functions (an external device may write or read from a controller).
Modbus registers corresponding to objects in the controller can be exported to text form in GenConfig.

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
Communication Guide and to I-CBEdit manual.
7.18 User MODBUS
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.
