The following, however, is an exception. In this case, a local network table does not
need to be registered even if there is more than one Network Communications Unit.
If a local network table is not registered, network access will be possible to only the
network of the Communications Unit with the smallest unit number when a direct
serial connection is made to a target PLC.

Note: In this context, the following are Network Communications Units: Ethernet Unit, Controller
Routing tables are required when communicating with another PLC in a network
outside of the local network.
Setting routing tables makes it possible to communicate with other network levels
using FINS message communications or the CX-Programmer’s remote programming
and monitoring functions.
To set the routing tables, start the Routing Table Component. The Routing Table
Component can be started with either of the following methods.
For details on making the routing table settings in the Routing Table Component, refer
to 3-2-2 Creating the FINS Local Routing Tables.
Method 1:
