Programmable Logic Controller (PLC) is a kind of digital arithmetic controller which is automatically controlled by microprocessor. It can load control instructions into memory for storage and ex*****on at any time. Programmable controller consists of CPU, instruction and data memory, input/output interface, power supply, digital-to-analog conversion and other functional units. The early programmable logic controller only had the function of logic control, so it was named programmable logic controller. Later, with the continuous development, these simple computer modules have many functions including logic control, time sequence control, analog control, multi-computer communication and so on.Programmable logic controller (PLC) is a digital operation electronic system specially designed for industrial environment applications. It uses a programmable memory to store instructions for logical operation, sequential control, timing, counting and arithmetic operation, and controls various types of mechanical equipment or production processes through digital or analog input and output. With the development of Industry 4.0, PLC programmable logic controller has gradually become the mainstream of industrial intelligent control, and with the addition of various intelligent devices, PLC has formed a brand-new configuration control device, which is more advanced and even has an industrial touch screen for configuration control. In the intelligent industrial environment, the official reasons for the application of PLC configuration control are as follows:
touch screen
The implementation control method is realized by software programming, which is easy to change.
The action sequence depends on the scanning sequence of the program, that is, working in a "serial" way can avoid contact competition. 2
