    Hello,

    I would like to use R_TRIG with some condition after like below:

    R_TRIG(IN:=Start1)

    if R_TRIG.Q THEN
    do something
    if something then
    do
    end_if
    end_if

    but when I do that after the condition with R_TRIG.Q, all of the condition are blocked i don't know why if U can help me

    oneshot : R_Trig;

oneshot(clk:=start1);

if oneshot.q then
    something := true;

    if something then
          otherThings := true;
    end_if
end_if

if reset then
   something := false;
   otherThings := false;
end_if

    Keep in mind, oneshot.q is only ON for one scan once start1 goes true. Oneshot.q goes off after one scan even if start1 remains true.

    I hope you find this helpful
