What is Industrial Ethernet?

      What is Industrial Ethernet?Due to its inherent reliability, high performance and interoperability, Industrial Ethernet has penetrated into the factory floor and is the communication protocol of choice for automation and control systems. In recent years, the industrial market share of industrial Ethernet has surpassed the traditional fieldbus protocol, which usually requires multiple independent and proprietary wiring facilities.


      To meet the needs of the industrial environment, Industrial Ethernet essentially uses special industrial protocols encapsulated in the Ethernet protocol to ensure that the correct information is sent and received at the time and location where a particular operation needs to be performed.


      The four major protocols of Industrial Ethernet: Industrial data communication takes place at the routing, control and sensor layers – each layer requires different levels of real-time information transmission, collision detection and decision making (essentially between any two nodes) Routing).



      Although there are several industrial Ethernet protocols that support the various communication requirements of the factory, there are four main protocols worthy of attention - Modbus TCP/IP, EtherCat, EtherNet/IP and ProfinetModbus TCP/IP are the first industrial Ethernets to be introduced. A network protocol, which is essentially a traditional Modbus communication, compressed in an Ethernet transport layer protocol for transmitting discrete data between control devices. It utilizes simple master-slave communication where the "slave" node does not send data without a request from the "master" node, so it is not considered a true real-time protocol.
