Do not register SYSMAC BUS/2 Master Units and BASIC Units in local net-
work tables because these Units do not connect to networks.
The following example show the settings for a relay network table connecting
three networks.

On closer examination of the relay network table for PLC3, we see that the
relay network is B and the relay node is c when network A is the destination,
and that the relay network is B and the relay node is e when network C is the
destination.
