Abstract: | We developed the ADMAP ADvanced MAP) system as a local area network for our Distributed Instrumentaion Control System (DCS) with a broadcast communications function. ADMAP is an open system based on the Manufacturing Automation Protocol (MAP), which is advancing as an international standard, but also providing real-time performance, which is weak in MAP. The new MAP-based LAN can be used not only for electrical and computer control. This paper describes the new MAP-based LAN and discusses distributed control systems using this LAN to integrate instrumentation, electrical, and computer controls. |
