PLC control system, Programmable Logic Controller, is a kind of digital operation electronic device specially designed for industrial production. It uses a programmable memory for internal storage of programs and execution of user-oriented instructions such as logic operations, timing, counting and arithmetic operations. And control various types of machinery or production processes through digital or analog input/output. It is the core part of industrial control.
Since the introduction of Programmable Logic Controller (PLC) to replace traditional relay control devices in the United States in the 1960s, PLC has developed rapidly and has been widely used around the world. The function of PLC is also continuously improved.
With the continuous development of computer technology, signal processing technology, control technology network technology and the continuous improvement of user needs, PLC has added analog processing and motion control functions on the basis of switching quantity processing. Today’s PLC is no longer limited to logic control, but also plays a very important role in motion control, process control and other fields.
PLC is equivalent to the brain of the machine, and the program we make is equivalent to the knowledge and rules that people hold. The machine is equivalent to the human body, which is used to perform various actions of the PLC. Electricity, gas, liquid, etc. is equivalent to human muscles and nerves, PLC issues instructions, and transmits energy to the machine through electricity, gas, liquid, etc., and the machine executes.
The sensor feeds the external situation to the PLC, which is equivalent to the human eyes, nose, etc., and then feeds the external things back to the brain.
Take a person or an animal for example, PLC is the brain, the combination of PLC and the machine is equivalent to the combination of the human brain and the body, but the program in the human brain is much more complex than the PLC, but the sensitivity and accuracy of the human brain is less than the PLC.
