Assignment of the node address for the data exchange between Lenze devices
If Lenze devices are assigned with node addresses in a complete ascending order, the
identifiers of the event−controlled data objects (CAN2_IO/CAN3_IO) are factory−set so
that the devices are able to communicate with each other.

Fig. 14−13 Data exchange between Lenze devices
Assign each node within the system bus network to a node address ˘ also called node ID
˘ for a clear identification in the range 1 to 63.
ƒ A node address may not be assigned more than once within a network.
Note!
The "8.1.1 Setting of CAN node address and baud rate" chapter contains
information on
ƒ Setting of the node address ( 156).
ƒ Individual addressing ( 160).
