Node address (Node ID)

Assign a node address − also called Node ID − within the range of 1 to 63 to each node within the
system bus network as a definite identification.

The same node address may not be assigned more than once within the network.

The configuration of the node address for the CAN−AUX interface of the PLC is effected via
code C2450:

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 (CANaux2_IO/CANaux3_IO) are set in way by the factory which
enables a communication from one device to the other:

Node-ID 1

FIF-CAN2_OUT

FIF-CAN2_IN

FIF-CAN3_OUT

FIF-CAN3_IN

Node-ID 2

FIF-CAN2_OUT

FIF-CAN2_IN

FIF-CAN3_OUT

FIF-CAN3_IN

Node-ID 3
