Abstract

In this paper, a method for the efficient implementation of the control network for a distributed control system (DCS) is proposed. The proposed method focuses on the real-time property and the low networking cost of a control network. It suggests a new network architecture combining the IEEE 802.4 token-passing bus access method and the IEEE 802.3 physical layer. For this purpose, a new interface, a physical layer service translator is introduced. A control network using this method is implemented and applied to a DCS.
