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/CX-Integrator Controller

Link Unit

Node address: 1

IP address: 192.168.250.1

Ethernet Unit

IP address conversion: Automatic generation method (dynamic)

Ethernet port

Ethernet (network address 1)

Routing according to routing table

Routing to final network address 2 requires relaying through node address 2 of relay network address 1 (Ethernet Unit).

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).
