More and more factory level DCS have begun to be centralized due to their ability to log in to remote devices. Due to the interconnection brought by wireless communication and remote access technology, the importance of physical distance between devices has decreased, which allows operators to control both the enterprise level (macro) and the device level (micro), either inside or outside the factory.
The programmable logic controllers currently used in industry are equivalent to or close to the mainframe of a compact computer, and their advantages in scalability and reliability make them widely used in various industrial control fields. Whether in computer direct control systems, centralized decentralized control systems DCS, or fieldbus control systems FCS, there is always a widespread use of various types of PLC controllers. There are many manufacturers of PLC, such as Siemens, Schneider, Mitsubishi, Delta, etc. Almost all manufacturers involved in the industrial automation field will provide their PLC products.
DCS, also known as distributed control system, is a multi-level computer system composed of process control level and process monitoring level, connected by a communication network, which integrates 4C technologies such as computer, communication, display, and control.
Usually, a hierarchical structure is adopted, with each level consisting of several subsystems that achieve specific finite goals, forming a pyramid structure. Its main feature is its centralized management and decentralized control.
The DCS control system disperses control functions across various computers, with each computer undertaking a single system task. Failure of any computer module will not affect other computer systems
The DCS control system has advanced hardware equipment that can operate in various harsh working environments; The system has automatic recognition and fault diagnosis functions, making it easy for operators to maintain and handle
