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 FIF 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 (FIF_CAN2_IO/FIF_CAN3_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
