A fault diagnosis procedure is executed before each scan of the user program. The content of self-diagnosis is I/O part, memory, CPU and so on. Abnormal stop display error is found. If the self-diagnosis is normal, continue scanning down.
2) PLC check whether there is a communication request with the programmer and the computer, if there is a corresponding processing, such as receiving programs, commands and various data sent by the programmer, and to display the state, data, error information sent to the programmer for display. If there is a communication request with the computer, etc., the data is also received and sent during this time.
3) The central processing unit of PLC scans each input terminal and sends the state of the input terminal to the input status register, which is the input sampling stage.
4) The CPU will call and execute the instructions one by one to “process” the input and the original output state (these states collectively referred to as data), that is, carry out logic and arithmetic operations on the data according to the program, and then send the correct result to the output state register, which is the execution stage of the program.
