Process Control is based on the PneumaTIc signal standard of 3~15psi ground-based pneumatic control instrument System (PCS, PneumaTIc Control System), that is, the first generation of process control architecture; ACS (electric unit modular analog instrument Control System) based on analog current signal standard 0 to 10mA (4 to 20 mA) is the second generation of process control architecture. In the 1970s, due to the use of digital computers, the centralized digital control System (CCS), the third generation of process control architecture, was produced. In the 1980s, the emergence and application of microprocessor resulted in the generation of Distributed Control System (DCS, Distributed Control System), that is, the fourth generation process control architecture; In the 1990s, the emergence of Fieldbus technology produced a new generation of process control architecture, that is, Fieldbus ControlSystem (FCS).

The basic characteristics of PLC control system

(1) From the switch quantity control to the development of sequence control, operational processing, from the bottom up;

(2) logic control, timing control, counting control, step (sequence) control, continuous PID control, data control - PLC has data processing capabilities, communication and networking functions;

(3) A PC can be used as the main station, and multiple PLCS of the same type are the secondary station;

(4) A PLC can also be the main station, and multiple PLC of the same type can be the slave station to form a PLC network. This is more convenient than using a PC as the main station: when there is user programming, you do not have to know the communication protocol, as long as it is written in instruction format;

(5) The PLC network can be used as an independent DCS/TDCS or as a subsystem of DCS/TDCS;

(6) Mainly used for sequence control in industrial processes, the new PLC also has closed-loop control function.

Distributed Control System (Distributed Control System), also known as computer distributed control system, it was rapidly developed in the mid-1970s, it is a multi-level computer system composed of process control level and process monitoring level with communication network as a link. It combines control technology, computer technology, image display technology and communication technology to realize the monitoring, control and management of the production process. It not only breaks the limitation of the conventional control instrument function, but also better solves the danger brought by the early computer system for the information, management and control function too centralized. It is mainly used in large-scale continuous process control systems, such as petrochemical, electric power and so on. At its core is communication, the data highway.

Its basic gist is:

(1) A tree-like system from top to bottom, where communication is key.

(2) PID In the interrupt station, the interrupt station connects the computer with the field instrument and control assembly. ;

(3) is a tree topology and parallel continuous link structure, with a large number of cables parallel to the relay station to the field instrument.

(4) The signal system includes switching signal and analog signal.

(5) DCS is a three-level structure of control (engineer station), operation (operator station), and field instrument (field measurement and control station).
