To ensure that all nodes can intercommunicate, you must assign them an address:
• In the MPI network: an “MPI address“
• In the PROFIBUS DP network: a “PROFIBUS DP address“
On the PG you can specify individual MPI/PROFIBUS addresses for each one of
the nodes (on some of the PROFIBUS DP slaves this is also possible per selector
switch).

The table below shows you the factory setting of the MPI/PROFIBUS DP
addresses and the highest default MPI/PROFIBUS DP addresses for the devices.

Note the following rules before assigning MPI/PROFIBUS addresses:
• All MPI/PROFIBUS addresses in a subnet must be unique.
• The highest MPI/PROFIBUS address must be ≥ of the physical
MPI/PROFIBUS address, and it must be identical for each node. (Exception:
Connecting a PG to multiple nodes; refer to the next Chapter).
