Can I avoid the intersection of two maintenance?

I am attempting to prevent the intersection between MTBF/MTTR and the Time Table using a FlexSim script code to enable and disable the Time Table. However, I'm not achieving the desired result. Even when I disable the Time Table during the breakdown, it still performs the action. I am attaching the model I am using along with an image of the current simulation outcome and the desired one. Your assistance would be greatly appreciated.

model.fsm

Software Version:

FlexSim 23.2.1

mtbf mttr timetables customcode

MTBF/MTTR can you apply to a set of states that count as uptime. If you exclude a state of scheduled down, that is perhaps your state of a break in a timetable, then a breakdown cannot happen while an object is state scheduled down.

For the other way around, preventing the time table from changing the state when a breakdown is active, you could do something as simple as only running the Down and Resume Function code if the object is/is not in the correct state.

Thank you very much for attaching the FSM model with the solution. It helps me visualize the proposed conceptual model.
