Software process Practical application After the system was installed and debugged, it was officially put into use in October 1999. It has been running stably for more than two years and has calibrated nearly a hundred flowmeters (times) without any problems in the control system. Practice has proved that the system has a high degree of automation, and all performance indicators fully meet t...
Application of PLC, DCS and FCS in metallurgical process control In metallurgical production, the process control system completes the detection, display, recording, adjustment, control, alarm and other functions of the generated process parameters. play an extremely important role. Its characteristic is to control the real-time production process, the control process is complicated, the process l...
Difference of DCS, PLC and FCS in system 1. Main points of difference (1) How much I/O information the system can handle. (2) How much control-related control loop information the system can handle. (3) How many users and devices (CRT, control station, etc.) can be adapted. (4) How thoroughly the integrity of the transmitted data is checked. (5) What is the maximum allowable length of the d...
The basis of the FCS system is a digital intelligent field device. The digital intelligent field device is the hardware support and foundation of the FCS system. The reason is very simple. The FCS system implements the two-way digital communication field bus signal system between the automatic control device and the field device. If the field device does not follow the unified ...

It is a holiday shared by working people all over the world. In July 1889, the Second International, led by Engels, held a congress in Paris. The meeting passed a resolution stipulating that international workers would hold a parade o...
(1) The DCS system is a large system. Its controller has powerful functions and plays an important role in the system. The data highway is the key to the system. Therefore, the overall investment must be made in one step, and sub- sequent expansion is difficult. However, the functions of FCS are completely decentralized, information processing is on-site, and digital intelligent field de...
PLC technology, as an important technology in modern industrial control, is widely used in all walks of life and in all aspects of production, and has received widespread attention and importance. Along with the depth of the application field, the price of PLC systems is becoming more and more the focus of attention, effectively controlling the cost of the system will greatly promote the popularit...
