■ 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)
