Ethernet communication module is usually used as the communication interface of PLC. It is based on the traditional Ethernet communication mechanism and uses Ethernet and TCP/IP protocols as the communication basis. It can provide absolute support for TCP/IP communication in any situation. The Ethernet communication module allows the PLC to send and receive data on the LAN or the Internet to realize automatic transmission of information. This communication method can reduce the time occupied in communication and improve the performance of automated data refresh.

In order to meet the real-time requirements in automation, the optimized real-time communication channel based on the PLC Ethernet layer reduces the time occupied in communication and improves the performance of automated data refresh. As an access technology, PLC Ethernet communication provides the "last mile" solution for broadband networks and is suitable for residential areas, schools, hotels, office buildings, and other fields.
