专利汇可以提供Signal inputting method in process controller专利检索,专利查询,专利分析的服务。并且PURPOSE: To provide a signal inputting method which is highly reliable by constitut ing same such that, when a signal from an external process is input to a process controller, the signal is considered to be effective only if it continues for a predetermined fixed period of time from the initiation of its input.
CONSTITUTION: In the flow chart, an input processing is initiated when an input signal changes from the preceding state. Then, delay of a preselected period of time is effected (32), and only if the input signal does not change for the delay period of time, it is received as a normal signal (33). If there should be any change of the input signal, the delay value is restored to the initial value and delay is initiated again. The signal received is adopted as a normal signal and hence the input processing operation is ended.
