Working Principle
Its working principle is based on the scanning mode of PLC, which mainly includes three stages: input sampling, user program execution, and output refreshing. Completing these three stages is called a scanning cycle. During the entire operation period, the CPU of the PLC will repeat the above three stages at a certain scanning speed. The details are as follows:

Input Sampling Stage: The CE3008 module sequentially reads all input states and data through scanning and stores them in the input image register. At this time, the content in the input image register will change with the state change of the external input circuit.

User Program Execution Stage: The module starts from the first instruction of the user program and scans and executes the user program in the order from top to bottom and left to right. During the scanning process, it will perform calculations according to the logical relationship set in the program based on the data in the input image register and the state of other soft components, and store the calculation results in the corresponding soft component image register.

Output Refreshing Stage: After the execution of the user program is completed, the module will refresh the data in the output image register to the output latch, and then the output latch will drive the external load, thereby realizing the control of external equipment.
