5.2 Setting Up the Master
5.2.1 CC-Link
To operate a CC-Link system, the network parameters of the PLC must be set. These parameters are set using Mitsubishi
Electric’s sequencer programming software GX-Developer.
• Network parameters
These parameters are set in the master station and include the number of CC-Link units connected, buffer memory of the
master station (RX, RY, etc.), address of the CPU device to be refreshed automatically, number of retries after failed
communication, and station information.
How each parameter is set is explained below, along with a setting example. For details, refer to the CC-Link operation
manual for your PLC.

OK button.
