CC-Link IE Controller Networks achieve the communication speed of 1 Gbps. Here, the token method is adopted as the data
transfer control method. The token method does not cause any collision of frames in the transmission path, improving the
throughput of communication. Therefore, it is optimal for networks where regular schedule communication is required.
