Description: PLC/DCS Module
Country: USA
PLC (Programmable controller) is a control device, while DCS (distributed control system) is a system. DCS is a “decentralized control system”, while PLC is a “programmable controller”, the two are the difference between “system” and “device”. In terms of design and structure, DCS has a large number of expandable interfaces throughout the design, and it is convenient to access external systems or extended systems. After the design of PLC is completed, it is difficult to increase or reduce the operating station arbitrarily.
In terms of security, DCS uses double redundant control units, when an important control unit fails, there will be relevant redundant units in real time without interference to switch to the working unit, to ensure the safety and reliability of the entire system. In the design of PLC, there is no redundant concept, and there is no redundant control strategy. In terms of communication, DCS network is the central nervous system of the whole system, it is a safe and reliable dual-redundancy high-speed communication network, the system has good expansibility and openness.
