The short execution time of 3805E can speed up the response speed of PLC to general input signals. From discussing the working principle of PLC, we can see that from adding input signals to the PLC to generating output from the PLC, the 3805E ideally also needs to delay the cycle of a PLC operation program. Because PLC monitors the input signal, the output generated after running the program is the response to the input signal. When it is not ideal, the 3805E needs to extend another cycle. When the input signal is sent to the PLC, the PLC input refresh just ends, which is the case. At this time, it is necessary to wait one more cycle before the input mapping area of PLC can receive the new input signal. Although this delay is acceptable for general input signals, the 3805E is not acceptable for input signals in urgent need of response. How long can the PLC respond to the input signal that needs to be processed

3805E In order to deal with the input signals that need to be responded, PLC has various measures. Different PLC measures are not the same, and the effect of improving response speed is also different. The general practice of 3805E is to use input interruption and then output immediate refresh, that is, after interruption of program operation, 3805E related output points will be refreshed immediately, instead of refreshing after the end of the whole program operation.
