Signal reset while looping

Hello collegues,

Is there a possibility to lets say “change signal variable” until the source process node will send new data?

I have two nodes. On the right side is ordering system and on left side workstation which is consuming components.

The worstation is sending signal to the ordering system about “how many components was consumed = QTY of components to be distached”. Ordering system is distachting acumulated orders once per hour and sends signal to workstation about how many components was dispatched. This number is then used to shorten consumed parts in workstation variables.

The problem is when workstation is looping the statements, it’s reading always same signal with quantity of dispatched components which was already used prevous loop.

*I cannot use “WaitTrigger” in signal propties.

Thank you for any advices.
