Local Network Table Settings Required
•
A local network table is required when there is even one other node in the same
network in which routing tables have been set already.
•
A local network table is required when there are two or more Network
Communications Units (see note) mounted to a single CPU Unit.

Note: Network Communications Units include Controller Link Units, Ethernet Units,
CS/CJ-series DeviceNet Units, SYSMAC LINK Units, and SYSMAC NET Link Units.
Note
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.
Relay Network Table Settings Required
Communicating across Network Levels
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.
