1. Introduction 1. Why use Ethernet for communication? Ethernet refers to a local area network that complies with the IEEE 802.3 standard. It is a type of internet technology, and since it occupies the highest proportion in networking technology, many people directly equate Ethernet with the internet. However, IEEE also has other local area network … Read more
TCP/IP ProtocolThe TCP/IP protocol (Transmission Control Protocol/Internet Protocol) is the most widely used protocol today, encompassing over 100 protocols used on the Internet, with the two most important being TCP and IP. Due to its cross-platform and routable characteristics, TCP/IP enables the interconnection of networks and communication across different network segments. This has led many … Read more
After introducing the content related to OPC UA communication, we have basically covered the main communication buses and protocols related to industrial automation. So, why have we focused on communication for nearly two years? Of course, for PLC/PAC engineers, or for electrical engineers or automation engineers, the core is not just communication; there are also … Read more
