Network Conditions That Require Routing Tables
Routing Table Settings not Required
Setting Example
The following example shows the routing tables that route communications from PLC1
(network address 1, node address 1) to PLC4 (network address 3, node address 2).
When necessary, set the routing tables (local network table and relay network table)
in the PLC as shown in the following table.

To go to network address 3, first it is
necessary to go to node address 3 (c)
in network address 1.
Destination network (a) sets both
network address 3, and network
address 2, which must be passed in
order to reach network address 3.

Network usage
One Communications Unit is mounted
in the PLC, and that Unit is connected
to one network.
Two or more Communications Units are
mounted to one PLC (CPU Unit).
Routing tables have been set in at least
one other node in the same network.
Communications are made across
network levels.
Routing tables are not required when just one Communications Unit is installed in
each PLC and those Communications Units are connected in a single network.
