Programmable Logic Controller (PLC) is a digital arithmetic controller with a microprocessor for automation control, which can load control instructions into memory for storage and execution at any time. A programmable controller consists of functional units such as CPU, instruction and data memory, input/output interfaces, power supply, and digital to analog conversion. Early programmable logic c...
Distributed control system is a new generation of instrument control system based on microprocessors, adopting the design principles of decentralized control functions, centralized display operations, balancing separation and autonomy, and comprehensive coordination. Distributed Control System, abbreviated as DCS, can also be translated as "Distributed Control System" or "Distributed Computer Cont...
