Working Principle of Industrial Ethernet Switches
The industrial Ethernet switch connects to various field devices such as sensors, PLCs and HMIs through physical interfaces. When industrial devices need to communicate, they send data packets to the switch. The switch identifies the destination based on MAC addresses and forwards the packets to the corresponding ports.
