Hi i work in a company and im a "process operator" and i wanted to make a change in one program that would require me to write something along the lines of
IF (signaldi = 0)
<movement>
ENDIF
But when i do it and run it pp jumps to ERROR on the code at the bottom.
and im quite lost. i have tried so many different ways.
i do not want to do a while loop as that could cause a problem.
i want to check once if a signaldi is on or off and do an action of its off.
