Industrial Ethernet is a field bus developed based on Ethernet system that is more suitable for use in industrial production environments. Currently, the mainstream types of industrial Ethernet include:
1. MODBUSTCP/IP, which was developed by French Schneider company.
2. Ethernet/IP, which is an industrial Ethernet type developed by Rockwell Corporation of the United States, is widely used in North America.

3. Ethernet/POWERLINK is an industrial Ethernet developed by B&R (B&R) in Austria. You can understand it as ethernet+CANopen.
4. Profinet, which is an industrial Ethernet developed by Siemens AG of Germany. With the help of the huge user group of Siemens PLC, Profinet has now become one of the most recognized industrial Ethernet types.
5. EtherCAT, which is an industrial Ethernet developed by German Beckhoff company, has lower communication delay, faster response speed, and supports more connection nodes. Many PLCs and industrial computers will integrate related bus interfaces.
6. SERCOSIII is an industrial Ethernet developed by German Rexroth Company, which is suitable for automatic control projects of mechanical engineering and construction.
