it is the problem of wire / cable or executive components, which will not be discussed in depth in this paper. If the PLC output signal is abnormal, you need to check the program to see which conditions are not met, and continue to track until you find out the program problem, or input the problem, and accurately locate the fault point. Continuous fault means that the state of the fault point remains unchanged, such as a sensor hardware fault, and the signal maintains a fixed state. Here we will continue to discuss in two cases. If it is a continuous signal, you can use programming software to directly find the problem source online. If the logic is simple, you can even directly check the state of the input (DI) to determine the fault point. For example, if a device fails to start, you can troubleshoot it calmly.
Even if the cause of the fault continues, if the time of action is relatively short, it should still be judged according to the short-term fault described later. For example, for a position sensor of a mobile device, the signal will be high for a short time only when the device passes the position, and it will be low at other times. If the sensor loses power and the signal remains low, the fault will not appear before the equipment passes.
