improves the programming environment.
In FCS, the basic structure of the system is: industrial computer or commercial PC, fieldbus master station interface card, fieldbus input/output module, PLC or NC/CNC real-time multi-task control software package, configuration software and application software. The main functions of the upper machine including the system configuration, database configuration, history library configuration, graphics configuration, control algorithm configuration, data report configuration, real-time data display, historical data, graphical display, parameter list, data printing, data input and parameter modification, control arithmetic, alarm processing, fault processing, communications control and man-machine interface and so on various aspects, And really realize the control centralization, risk dispersion, data sharing, completely open control requirements.
5 conclusion
From the previous discussion, it can be seen that the key technology of FCS is intelligent instrument technology and fieldbus technology. Intelligent instrument not only has the advantages of high precision,
self-diagnosis, and control function, will replace the traditional 4-20mA analog instrument. The fieldbus connecting the field intelligent instrument is an open, digital, multi – contact bidirectional transmission serial data path, which is a combination of computer technology, automatic control technology and communication technology. Combined with the rich
