Abstract:The development trend of industrial control system is industrial control network of the Ethernet. It is an important task for the industrial control theory field currently to study the key technique of the high - speed ethernet, including resolving real - time performance, operability, credibility, anti - interference and the essence safety etc. In the meantime researching and developing field equipments of control network, control system of network and control system software is also very important. Analyze the industrial control ethernet network principle, related performance and the industrial control ethernet protocols in common use. We draw a conclusion： though various industrial ethernet protoeal may exist in the meantime like the field control bus, the
