Process Engineering Division – Instrumentation and Automation Section – Daily Question – Question from 2020-09-16: Discussion question: 237. What are the main components of a DCS system?
A DCS system generally consists of five components: 1: Controller, 2: I/O board, 3: Operator station, 4: Communication network, 5: Graphics and supervision software.
Control unit (control station, the core component of DCS); Node units (various cards used to receive various types of signals from the field); Network units (usually there are two types of networks: the control network and Ethernet, used for communication between the operator stations and engineer stations); Human-machine interface (engineer station, used for configuration purposes). Operation station, used for actual operations. Of course, the engineer station can also be used as an operation station.) Power supply section (power supply for the control station, power supply for the nodes, 24V power supply for instruments and relays, 220V power supply including UPS, etc.)
1. DCS system: In China’s automation industry, it is also known as a distributed control system. It is a multi-level computer system composed of a process control level and a process monitoring level, connected by a communication network; it integrates the 4C technologies of computing, communication, display, and control. Its basic principle is decentralized control, centralized operation, hierarchical management, and flexible configuration... 2. DCS has components: the process level, the operation level, and the management level.
