Industrial automation is the trend of widely using automatic control and adjustment devices in industrial production to replace manual operation of machines and machine systems for processing and production. Under the conditions of industrial production automation, humans only indirectly take care of and supervise machines for production. With the development of control technology, computer, communication, network and other technologies, the field of information exchange and communication is rapidly covering various levels from the on-site equipment layer of factories to control and management.
Industrial Ethernet technology provides an open and compatible network architecture that meets the communication protocols and network applications of industrial control standards. The industrial environment requires high reliability of control networks, and industrial Ethernet must have ring network redundancy backup function; The industrial environment is extremely harsh, and industrial Ethernet switches are specifically designed for industrial environments. The product operates in environments with strong electromagnetic interference, vibration, high and low temperatures.
