ABB LD800HSE 3BDH000320R0101 ABB automation spare parts refers to the machine equipment or production process in the case of no direct manual intervention or less intervention, according to the expected goals to achieve measurement, control and other information processing and process control. According to the functional division, automation control specifically includes control system, drive system, feedback system, execution system, motion control system, etc. The control system is known as the "brain" of the factory, is the center and foundation of industrial production, especially process industry, and its safety, stability and efficiency directly affect the production process of each production link. The traditional control system generally includes instrumentation system, DCS system, PLC system, SIS system, SCADA system, executive regulation system and so on.

ABB LD800HSE 3BDH000320R0101 ABB automation spare parts are distributed control system, which is composed of input and output module, communication module, controller and man-machine interface. It is a kind of controller and field equipment as the basis, the relevant process signals are gathered into the system, and the operation station carries out monitoring or other control operations. Industrial automation control system with decentralized control, centralized operation and hierarchical management as the main characteristics. Compared with local logic control, DCS pays more attention to analog control, so DCS system has stronger data transmission and management capabilities, which is also the main reason why DCS system is widely used in large-scale projects.

ABB LD800HSE 3BDH000320R0101 The field of ABB automation spare parts control is undergoing an unprecedented change, beginning to develop in the direction of networking. The structure of the control system from the initial CCS (computer centralized control system), to the second generation of DCS (decentralized control system), to the now popular FCS (fieldbus control system). The demand for large data volume and high speed transmission, such as images and voice signals, has spawned the combination of industrial Ethernet and control network.
