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.

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.
• CS-series PLCs
Note
• Always turn OFF the power to the PLC before setting the rotary switches.
• Create I/O tables for the CPU Unit when setting the unit number for the first time or chang-
ing settings.
