An analysis and application research on a foundation fieldbus high speed ethernet

The amount of information increases with the improvement of industrial automatization level.The control network consisting of a low speed fieldbus needs higher bandwidth to transfer real time information.Increasing the communication speed and open mode is always the emphases on the fieldbus research.The high speed ethernet with a foundation fielbus in combination with the technology of an ethernet represents a standard high speed and open fieldbus.The paper also analyses the cmmunication architecture and the features of HSE,such as redundancy and flexible function blocks along with an application example.
