5.3 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

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:
L
Node-ID 1
FIF-CAN2_OUT
FIF-CAN2_IN
FIF-CAN3_OUT
FIF-CAN3_IN
L
Node-ID 2
FIF-CAN2_OUT
FIF-CAN2_IN
FIF-CAN3_OUT
FIF-CAN3_IN
L
Node-ID 3
