Using FINS Applications

Section 6-5

System Configuration Example 2: Using Routing Tables

In this example, an online connection is made via the Ethernet to a PLC on a
Controller Link network (PLC 3 below) from a CX-Programmer/CX-Integrator
connected to the Ethernet network.

Conditions

• FINS/UDP method

• IP address conversion: Automatic generation method (dynamic)

CX-Programmer's Change PLC Dialog Box

CX-Programmer's Unit Setup

Setup Tab

Same as for System Configuration Example 1.

Routing Table Settings and Transfer to Each PLC

Set the routing tables with CX-Integrator, and transfer them.

1.

Using CX-Integrator, connect online, and select Routing table

Settings.

Then create FINS local routing tables (a local network table and a relay
network table).
