PLC is a programmable logic controller, which is a kind of digital operation and operation electronic system specially designed for application in industrial environment. It uses a programmable memory and stores instructions for performing logical operations, sequence control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production through digital or analog input and output. process.

The input unit is the input interface between the PLC and the controlled device. It is a bridge for the signal to enter the PLC. Its role is to receive signals from the master component and the detection component.

Working principle:

After the programmable logic controller is put into operation, its working process is generally divided into three stages, namely input sampling, user program execution and output refresh. The completion of the above three phases is called a scan cycle.

In the input sampling phase, the programmable logic controller reads all input states and data sequentially in scan mode and stores them in the corresponding cells in the I/O map area. After the input sampling ends, it goes to the user program execution and output refresh phase. During these two phases, even if the input status and data change, the status and data of the corresponding unit in the I/O map area will not change. Therefore, if the input is a pulse signal, the width of the pulse signal must be greater than one scan cycle to ensure that the input can be read in any case.
