Technology and Application of Fieldbus Control System ---------Intelligent Equipment & Measurement And Control System Based on Promoted by the new technological revolution that automation control technology is tending digitization and in the field of automation industry, Shanghai Aton Electric Co., Ltd. developed Intelligent Equipment & Measurement And Control System Based on as a high and new technology industrialization model project. It was a state hi-tech development project of 2000 and was approved by the mittee of Technology. Shanghai Aton Electric Co., Ltd. constructed production line of intelligent controller of pump and valve, relying on Shanghai Electric (Group) Corporation; constructed measurement and control system FCS R&D center of intelligent controller of pump and valve and built up mass production R&D basis, cooperating with Shanghai Jiaotong University and Shanghai University; constructed FCS remote diagnosis and service center of intelligent controller of pump and valve; constructed FCS training center of intelligent controller of pump and valve; founded mass production R&D basis along with the Rockwell Laboratory of Shanghai Jiaotong University and CIMS Center. 1 Summary (1)Fieldbus control system is a system applied to field of production and puterized measurement control equipment to realize both-way multinode munications. It is also called low-level work for open, digital and munications. Application: Flow Control System of Manufacturing; Process Control System; Traffic Control & Management; Building Automation. Features: Fieldbus control system is low-level low-bandwidth munication and work in industrial system as well as open system connecting puterized appearance. Intelligent instrument and controller are equal to puter. They make work with Fieldbus control system as the links plete munication and other tasks. (2)Difference between FCS and DCS,FCS is updated control system after DCS integrated with digital control system and dist
