System Architecture Design of Supervisory Software for Networked Control Systems

The supervisory software makes it possible to monitor the running status of various physical devices which may be geographically distributed among a wide range of areas, thus becomes very useful in fields like the process industry, electrical industry and so on. This paper introduces the system architecture design of the supervisory software which is a part of a practical implementation platform for networked control systems (NCS). Three different architectures of the software are presented. The first one is for small-scale applications in which the supervisory software can communicate with devices directly. The second one is for medium-scale applications within a local area network (LAN) where many users may want to access the system contemporarily. The last one is for large-scale, Internet-wide or wThe supervisory software makes it possible to monitor the running status of various physical devices which may be geographically distributed among a wide range of areas, thus becomes very useful in fields like the process industry, electrical industry and so on.
