Abstract

Abstract: The advantages of the connection mode of ECS into DCS were analyzed. In order to meet the demands of the sequential control of DCS, it is necessary to enhance the realtime and the reliability of ECS. Based on the analysis of various kinds of fieldbus adopted in current ECS and its networking mode, the networking mode of the interval layer and the station controlled layer, which is suitable to the ECS communication scheme in the actual projects, the hardware configuration mode and the softawre functions of the communication management machine were proposed.

Key words: electrical control system (ECS), distributed control system (DCS), fieldbus, reliability
