Opening Massflow conveyor by UpstreamOutputOrder

Hi,


We have made a simple example model of a situation that is happening in a real and bigger model. The situation is a massFlow conveyor with two side exits. At the start of the simulation these side exits are closed (UpstreamOutputOrder is set to 0). After 40 seconds there is a custom code in ProcessFlow that opens these side exit, by setting the UpstreamOutputOrder to 2.

Both conveyors start receiving cans, but this is not what we expected:

We would have expected that the green route would be the route the cans would take once the last horizontal conveyor was full, since all the horizontal conveyors have UpStreamOutputOrder 1, and the side exits have UpStreamOutputOrder 2. This is at least what we understood from the user manual:

https://docs.flexsim.com/en/22.0/Reference/3DObjects/Conveyors/MassFlowConveyor/#behavior

Is this a correct way of opening such side exits after a period of time, or is there another way of doing this? Any advise would be welcome.

This model looks a lot like my previous question, only difference in opening the conveyors with UpStreamOutputOrder 2 in stead of 1:

This seems to be working in 24.2.0.

It should be fixed in 24.0.5 as well.
