Note: 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.
5.4 Multiple ECU modules support
ID-DCU Industrial supports communication with up to 10 ECU modules. ECU means general Electronic
Control Unit and it can be engine control unit, speed governor, voltage regulator, ignition etc.
These interfaces can be used for communication with ECU modules:
CAN 1 J1939 for CAN bus communication, usually J1939 protocol based communication
RS485 for Modbus communication
It is possible to combine the interfaces (e.g. engine ECU connected via RS485 with ignition connected via
CAN1).
5.4.1 Multi ECU Configuration with DriveConfig
Use Modules card in DriveConfig to configure support of ECU modules with the Insert/Remove buttons:
IMPORTANT: Be aware that it is necessary to use ECU list, which enables use of multiple ECU
modules. Check and select used ECU list using this option:
