Allocation of the node address for the data exchange among Lenze devices

If Lenze devices are provided with node addresses in a consistent ascending order, the identifiers

of the event−controlled data objects (CAN2_IO/CAN3_IO) are set in way by the factory which enables

a communication from one device to the other:

Node-ID 1

CAN2_OUT

CAN2_IN

CAN3_OUT

CAN3_IN

Node-ID 2

CAN2_OUT

CAN2_IN

CAN3_OUT

CAN3_IN

Node-ID 3
