Introduction: In actual work environments, PLCs may communicate and exchange data. Typically, communication requires devices to be on the same network segment. However, what if our devices are not on the same segment? This article introduces how two PLCs can perform TCP/IP communication to exchange data when they are not on the same network segment. … Read more
What Is a Communication Network There is always a network around us, such as telephone networks, telegraph networks, television networks, computer networks, etc.; even within our bodies, there are many network systems, such as the nervous system and the digestive system. The most typical representative is the computer network, which is a combination of computer … Read more
