Common models:

DCS is a multi-level computer system composed of a process control level and a process monitoring level with a communication network as the link. It integrates technologies such as Computer, Communication, Display (CRT) and Control (Control).

DCS is a multi-level computer system composed of a process control level and a process monitoring level with a communication network as the link. Features of control, centralized operation, hierarchical management, flexible configuration and convenient configuration.

I/O in DCS control system

The control system needs to establish signal input and output channels, which is I/O. The I/O in DCS is generally modular. An I/O module has one or more I/O channels to connect sensors and actuators (regulating valves).

DCS control unit: A process control station is composed of several racks, and each rack can be placed with a certain number of modules. The rack where the CPU is located is called the CPU unit. There can only be one CPU unit in the same process station, and the other racks that are only used to place I/O modules are the I/O units. The I/O unit and the CPU are connected through a field bus.

Commonly used I/O signals are generally divided into: AI-analog input signal; AO-analog output signal; DI-digital input signal; DO-digital output signal

AC800F controller is a controller with fieldbus function launched by ABB company in 2000. It has rich fieldbus interfaces and can realize controller redundancy, communication redundancy and power supply redundancy. The system has supporting configuration software CBF, man-machine monitoring software DigiVis and corresponding additional software packages. It is very suitable for end users and design units to use in their own engineering projects, because there is almost no secondary development work.
