5-1 Connecting to Host Via Ethernet
tions Unit mounted at a node. If there is more than one Communications Unit at a node, each
Unit will contain a local network table.
Remote Network Table
The remote network table provides the node and network address corresponding to the initial
relay point (first point the data must pass) en route to a target network (end network) not di-
rectly connected to the local PLC. The table specifies the route from the relay point to the end
network.
PT at local
node
Routing tables are created using the CX-Programmer and then transferred to the host. Refer
to the CX-Programmer User Manual for actual procedures.
The methods for setting each Unit are described next.
