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 or CX-Integra-
tor 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).
