ControlTimer sometimes does not pause

I have a common event that is fed into a Change node where the output is set to PAUSE.

  • The output of that Change node is then sent to about 10 controltimers and they should all pause. (A similar common Change node outputs a CONTINUE and is sent to all controltimers to restart them.)

  • sometimes one or more controltimers continue to run after the PAUSE is sent (different timers suffer this problem from time-to-time)

Any ideas ?

Not without a good deal more information I'm afraid.

What are these controltimers? nodes? external applications? hardware devices? PLC?

How are they connected / what protocol / what nodes are used to command these controltimers?

How have you arranged your flow to perform this?
