For small PLCs, the number of I/O points is small and the user program is short. Generally, centralized sampling and centralized output are adopted. Although the response speed of the system is reduced to a certain extent, the PLC is isolated from the external input/output equipment for most of the time, fundamentally improving the anti-interference ability of the system and enhancing the reliability of the system.

For large and medium-sized PLCs, there are many I/O points, strong control functions, and long user programs. In order to improve the system response speed, a variety of methods can be adopted, such as regular sampling, regular output, or interrupt input, output, and intelligent I/O interface.

From the above analysis, it can be seen that when the input signal of PLC changes and the PLC output responds to the input change, it takes a period of time. This phenomenon is called PLC input/output response lag. For general industrial control, this lag is completely allowed. It should be noted that this response delay is not only caused by the PLC scanning mode, but also by the input delay caused by the filtering link of the PLC input interface, and the output delay caused by the action time of the driving device in the output interface, and also related to the program design. The lag time is a parameter that should be paid attention to when designing the PLC application system.
