The PLC controller was developed by imitating the original relay control principle. In the 1970s, the PLC controller only had switching logic control, and the first application was the automobile manufacturing industry. It stores instructions that perform operations such as logic operations, sequence control, timing, counting, and operations; and controls various types of machinery or production processes through digital input and output operations. The user-programmed control program expresses the process requirements of the production process and stores them in the user program memory of the PLC controller. The runtime is executed one by one according to the contents of the stored program to complete the operations required by the process flow. The CPU of the PLC controller has a program counter indicating the storage address of the program step. During the running of the program, the counter is automatically incremented by one every step of execution, and the program is executed from the initial step (step number is zero) to the final step (usually For the END instruction), then return to the initial step loop operation. The time required for the PLC controller to complete one cycle operation is called a scan cycle. Different types of PLC controllers, the cycle scan cycle is between 1 microsecond and tens of microseconds. PLC programming with ladder diagrams shows a fast advantage in solving logic. In the microsecond order, the 1K logic program is less than 1 millisecond. It treats all inputs as a switch, and 16 bits (also 32 bits) is an analog. Large PLC controllers use another CPU to perform analog operations. Send the calculation result to the controller of the PLC.
