Note 1. The same node address cannot be used for more than one Slave connected to the commu-
nications line.
Note 2. Remote I/O allocations in the CPU Unit are affected by the node addresses, so make sure that
the remote I/O allocations do not overlap before setting a node address. Refer to Chapter 4
