ABB 3BSC950089R2 digital signal output module cable

PLC is generally outsole layout frame, closed I/O modules, closed structure is beneficial and improve the reliability of I/O modules, anti-RF, anti-static, anti-damage. PLC module I/O points have 8 points, 16 points, 32 points.

DCS 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 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. The first is communication, that is, 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 (station), operation (operator station), and field instrument (field measurement and control station).

PLC and DCS systems are generally suitable for discrete and process manufacturing, respectively. Discrete manufacturing facilities using PLC systems are generally composed of a single production unit, which is mainly used to complete the assembly of parts, such as labeling, filling or grinding. Process manufacturing facilities, typically using automated systems, produce by recipe rather than piece in a continuous and batch manner. Large continuous processing equipment, such as oil refineries and chemical plants, use DCS automation systems. Hybrid applications usually use both PLC systems and DCS systems. Choosing a controller for an application takes into account many factors, such as process size, scalability and future plans, integration requirements, functionality, high availability, and the entire life cycle of the plant facility.
