    Good morning Felipe,

    Some things to check:
    – Is your rung true? You can put an output in parallel to your RTO to use for indication.
    – Is the ACC equal to the PRE? I.E. Has the Timer completed timing?
    – Is your RTO rung in Program File 2 (Main Routine)
    – Do you have a RES resetting the RTO?

    Hope this helps,
