(5) CC-Link
CC-Link has become wide spread mainly for FA as an open network for device level. Communication
specifications are open to the public, therefore, equipment in compliance with CC-Link can be
communicated without a program regardless of manufacturer.
Presently, CC-Link is spread and operated by CC-Link association (CLPA: CC-Link Partner Association),
which is a non-profitable organization.
Main features are as follows.
[1] Highly perfected saved
wiring communication which has realized complete multi-vendor connection.
[2] This is a unified standard, therefore, it can be used even overseas.
[3] Since slave equipment is handled as a PLC remote I/O to which CC-Link unit is installed,
communication can be made without a particular program.
[4] Since line efficiency is high, communication with high-speed response can be made.
※
For details of CC-Link, refer to Operation Manuals of the master unit and the PLC to be installed.
