Coupling to a Higher Level Control Unit (e.g. GCP)
1.
Recognition of status transferred via external sensors to the discrete inputs and transfer via the engine
CAN bus to the higher level control unit that is coupled with the IKD 1. Evaluation is proceeded according
to the configured action and additional steps are initiated.
2.
Output of signals to the relays that are received from the higher level control unit. For this feature it is
possible to configure the relays of the IKD 1 using the relay manager of the higer level control unit (please
note external description of higher level control unit).
Coupling to a PLC
1.
Recognition of status transferred via external sensors to the discrete inputs and transfer via the engine
CAN bus to the PLC that is coupled with the IKD 1. Evaluation is proceeded according to the program in
the PLC.
2.
Output of signals to the relays that are received from the PLC. For this feature the relays have to be con-
trolled from the PLC
