Abstract

In recent years, fieldbuses have been more widely used in real-time distributed control systems. There are many international fieldbus protocol standards, but they are not interoperable among themselves. This paper proposes an integrated fieldbus network architecture based on a switched Ethernet which provides real-time communication features to the nodes in different fieldbuses. This paper also analyzes the schedulability conditions for real-time periodic messages on the switched Ethernet and an EDF (Earliest Deadline First)-based scheduling algorithm to support the real-time communication requirements of the periodic messages without any change in the principles of the switch.
