CC-Link IE (Industrial Ethernet) is an extension of the CC-Link protocol that uses Ethernet as the physical communication medium. It was developed to provide a high-speed and reliable network for industrial automation and control systems. CC-Link IE offers several advantages over the original CC-Link protocol, including faster communication speeds, increased bandwidth, and greater flexibility in network configuration. It also supports a wider range of devices and applications, including motion control and safety systems. CC-Link IE is used in various industries, including automotive, food and beverage, pharmaceutical, and energy. It is designed to meet the demanding requirements of industrial applications, such as high reliability, real-time performance, and the ability to operate in harsh environments.
