Ethernet Switch

Aiming at the reliability of real-time industrial Ethernet, the L2 Industrial Ethernet switch is designed using VSC7429. With the respect of real-time capacity, it is based on the IEEE1588 standard by adding logic modules between MAC £ ̈Medium Access Control£© layer and PHY £ ̈physical£© layer to process the clock stamp. It eliminates the delay and uncertainty of the protocol stack and provides the accurate synchronous clock. In terms of reliability, dual hot backup power supplies were applied. Owing to the harsh environment of the industrial field, the EMC (Electro Magnetic Compatibility) protection design was considered. The performance of the switch was tested including packet loss rate and bit error rate. Experimental results showed it met the requirement of industrial Ethernet standard.
