3.3 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 PLC is carried out via code C0350:
Code LCD Possible settings Information

C0350 CAN address 1 1 {1} 63 System bus − node address
·
Save changes with C0003 = 1.
·
Changes are only valid after
reset node!
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:
L
Node-ID 1
CAN2_OUT CAN2_IN
CAN3_OUT CAN3_IN
L
Node-ID 2
CAN2_OUT CAN2_IN
CAN3_OUT CAN3_IN
L
Node-ID 3
