Classification of Control System of Combined Scale

Traditional single-chip microcomputer Control: 8-bit MCU and 32-bit single chip microcomputer.

New PLC Control: Siemens PLC, AB PLC The combined scale control system developed by PLC has higher reliability, stronger anti-interference, lower maintenance cost and can expand function according to user's requirement than the traditional single-chip microcomputer system. PLC mainly refers to the digital operation of the electronic system of Programmable logic controller, used to control the production process of machinery.

Also is the name abbreviation of Public Limited company, power line car and so on. PLC = programmable Logic Controller, Programmable logic controller, a digital operational electronic system designed for use in industrial environments. It uses a class of programmable memory for its internal storage programs, performs logical operations, sequential control, timing, counting and arithmetic operations, and user-oriented directives, and controls various types of mechanical or manufacturing processes through digital or analog input/output. is a core part of industrial control.
