Example 1: Local Network Table for a PLC With Multiple Units Mounted
This example shows the local network table settings for a PLC to which multi-
ple CPU Bus Units are mounted.

Example 2: Three Interconnected Networks
This example shows the relay network table settings for three different inter-
connected networks.
connected networks.
In the table for PLC #3, for example, if network #A is taken as the end net-
work, then network #B becomes the relay network and node #c becomes the
relay node. If network #C is taken as the end network, then network #B still
becomes the relay network and node #e becomes the relay node.
