5-5-1 Outline of Routing Tables
Routing tables must be set when the local node communicates with PCs, com-
puters, and other nodes on remote networks. Routing tables need not be set
when the node communicates only with other nodes on the local network.

when the node communicates only with other nodes on the local network.
Note For CVM1 or CV-series CPU Units manufactured before April 1996 (lot No.:

46), always set routing tables. Refer to the Controller Link Units Operation
Manual (W309) for details.
Routing tables define communications paths when a local node communicates
with nodes on remote networks.

The following is a network example and the data required to create routing tables
is explained below.

In this network example, when the PC connected to the Programming Device on
network 1 is to communicate with a PC on network 2, you need to create routing
tables containing the following information and transfer them to the PCs and
computer on network 2.

•
The local node belongs to network 1 (local network).
