In the input sampling stage, the PLC samples the input states of all input terminals in sequence in the scanning mode and stores them in the input image register. At this time, the input image register is refreshed. Then enter the program processing stage. In the program execution stage or other stages, even if the input state changes, the content of the input image register will not change. The change of the input state can only be sampled in the input processing stage of the next scan cycle.

Program execution stage

In the program execution phase, the PLC scans and executes the program in sequence. If the program is represented by a ladder diagram, it is always carried out in the order of top to bottom, left to right. When a program jump instruction is encountered, whether the program jumps is determined according to whether the jump condition is met. When the input and output states are involved in the instructions, the PLC reads them from the input image register and the element image register, performs operations according to the user program, and stores the results in the element image register. For the component image register, its contents will change with the process of program execution.
