1. OVERVIEW
The CC-Link system is a system that connects distributed modules such as I/O
modules, intelligent function modules, and special function modules using dedicated
cables so that these modules can be controlled by a programmable controller CPU.
This chapter describes outline of the CC-Link.
1
By distributing each module to the equipment device such as the conveyor line and
machine devices, the wiring conservation of the entire system can be accomplished.
2
Simple, high-speed communication can be accomplished with modules that handle
on/off data such as I/O or numeric data.
3
By connecting multiple programmable controller CPUs, a simple distributed system
can be configured.
4
Connections can be made to different types of devices made by partner
manufacturers, giving flexibility to the system.
