What is CC-Link
At the beginning of the popularization of Industrial bus networks, RS-232-based serial communication was the first to occupy the market, but there were many problems, such as common-mode interference, transmission distance and so on. In order to solve the problem of distance and speed, serial port communication based on RS-485 appeared. It optimizes the sending and receiving mode on the basis of RS-232 and uses two-wire system to realize 1-to-N communication, and launched the industrial site based on RS-485 Bus network, such as bus protocols such as CC-Link, CC-Link L/T and CC-Link Safety.
By the end of the 20th century, with the application of Mes system, ERP system, SCADA system, etc., there was a further demand for the amount and speed of data transmitted on the production site. At the same time, the popularity of the internet also greatly affected the industrial network. CC-Link Association Industrial networks based on standard Ethernet, such as CC-Link IE Control, CC-Link IE Field, CC-Link IE Field Basic, SLMP and CC-Link IE Safety, etc. have been launched.
Especially in recent years, with the implementation of 5G and the Industrial Internet of Things, more and more IT-based application software needs to interact with on-site FA information, posing severe challenges to network speed and data volume. At the same time, the market There are higher requirements for the use of ordinary Ethernet equipment and the high precision of driving equipment.
For these reasons, TSN technology has officially entered the field of industrial networks. The CC-Link Association officially released the CC-Link IE TSN industrial network in 2018.
In the future, the CC-Link Association will keep pace with the times and combine the fields of industrial 5G and information security to improve the CC-Link protocol family.
