Technical Drawing:
When the PLC controller is put into operation, its working process is generally divided into three stages, namely, input sampling, user program execution and output refresh. Completing the above three phases is called a scan cycle. During the entire operation, the CPU of the PLC controller repeatedly executes the above three stages at a certain scanning speed.
Output refresh phase
When the scanning user program ends, the PLC controller enters the output refresh phase. During this time, the CPU refreshes all the output latch circuits according to the corresponding state and data in the I/O map area, and drives the corresponding peripherals through the output circuit. At this time, it is the real output of the PLC controller.
The same several ladder diagrams are arranged in different order and the results are different. In addition, the results of the operation of the scanning user program are different from the results of the parallel operation of the hard logic of the relay control device. Of course, if the time taken by the scan cycle is negligible for the entire run, there is no difference between the two.
In general, the scan cycle of the PLC controller includes self-diagnosis, communication, etc., as shown in the following figure, that is, one scan cycle is equal to the sum of all the times such as self-diagnosis, communication, input sampling, user program execution, and output refresh.
