(1) Input sampling stage

In the input sampling stage, PLC reads all the input status and data successively by scanning and stores them into the corresponding unit in the I/O image area. After the end of the input sampling, the user program execution and output refresh phase. In both phases, even if the input state and data change, the state and data of the corresponding cell in the I/O image area will not change. Therefore, if the input is a pulse, the width of the pulse must be greater than one scan cycle to ensure that the input can be read in any case.

(2) User program execution stage

In the execution phase of the user program, the PLC always scans the user program in sequence from top to bottom (ladder diagram). When scanning each ladder diagram, it always scans the control circuit composed of contacts on the left side of the ladder diagram first, and carries out logical calculation on the control circuit composed of contacts in the order of first left and then right, first up and then down. Then, according to the results of logical calculation, the state of the corresponding bit of the logic coil in the RAM storage area of the system is refreshed. Or refresh the state of the corresponding bit of the output coil in the I/O image area; Or determine whether to execute the special functional instructions specified in the ladder diagram. That is, during the execution of the user program, only the state and data of the input point will not change in the I/O image area, while the state and data of other output points and software devices may change in the I/O image area or the system RAM storage area, and the status and data are listed in the above ladder diagram. The results of the execution of the program will be on the following general use of these coils or data ladder diagram play a role; In contrast, in the ladder diagram below, the status or data of the refreshed logic coil is only available to the program above it until the next scan cycle.
