how to implement Downtime in a process flow?

Imagine that a complex process flow is modeled for items in the queue. Now the problem arises when the Queue goes down (because of down time) but the process flow token continue to perform activities. Can you please provide a solution (or provide a pointer to the solution) to pause the process flow when the 3D object is down. Please note that the model cannot be shared due to hardware restrictions of the modeling computer.

Hi @Vaibhav R3 ,

downtimeprocessflow.fsm

This model is an example of using wait for event activities and a zone to stop the process flow when queue goes down. The MTBF/MTTR down behavior stops the output of the queue, and doesn't fire the 'send to port' trigger. Thus we can use a wait for event activity in process flow to wait until 'send to port' fires again (when the queue is back up and running) and the process flow continues.

Note: the zone is just to restrict one token at a time on the processor. There are other ways to do this

Hope this helps!
