Hi All,

I am new in robot programming, so apologize if my question is maybe a basic one.

I have an external software which sends an digital input to my IRC5 controller. The value 1 or 0.

I want to check the value of the DI during a period of time. In fact I want to be sure that the DI stays at the value 1 during at least 30 seconds. and then pass to the next action.

Is there any simple solution?


Thanks for your help

    This below will wait until the signal becomes logic HIGH (it will wait there infinitely until you reset program pointer or another method - add a maxtime and timeout signal to that if you want to) then checks it for your 30 seconds.

    VAR bool bSignal_High_For_30s;
    !
    WaitDI diInputSignal, 1;
    !
    bSignal_High_For_30s:=FALSE;
    WaitDI diInputSignal, 0 \MaxTime:=30 \TimeFlag:=bSignal_High_For_30s;
    !
    IF bSignal_High_For_30s=TRUE THEN 
        !
        ! signal high for 30 seconds
        !
    ELSE 
        !
        ! signal went low before 30 seconds expired
        !
    ENDIF
