Performance Analysis and Evaluation of Industrial Ethernet

Because of a wide range of Industrial Ethernet and the great difference between them, it is a difficult problem to select which one is proper when designing an automation system. The huge advantages of Industrial Ethernet are discussed, so are the protocol model and technologic characteristics. The usage patterns and the usage percentages of industrial Ethernet are analyzed. Then the performance of industrial Ethernet is compared and evaluated. Especially, this paper presents that after consideration for some factors, such as development expense and complexity, protocol compatibility, market share and etc, the suitable industrial Ethernet protocol can be selected according to the performance demand of the automation systems.
