Mixing tasks

Hi, I'm working on a model in which the transporters should load the queues to feed the machines (ML's) and then they have parallel tasks in the "MC1", "MC2", "Elev" but it seems that this tasks are mixing up, i.e. for example the transporter23 sometimes takes material from the queu03 and take it to the "Elev". In reality the transporter does one task one at a time.

mlall - teste.fsm

Thank you in advance 🙂

You do not acquire the transporter Process Flow resource when giving out tasks in the "Empty Tables" section (the only section where this is not the case, that I could fin). So these tasks can potentially mix with others.

[luis_rodrigues]

So what you recommend? Should I put a tasksequence?

[moehlmann_fe]

Either that or acquire the transporter before running the subflow-

I created Tasksequence for the "Move Empty" and it worked, is there a way I can automatically check that this doesn't happen with the other sub flows?

[moehlmann_fe]

Not really, no. I also came to the conclusion that you should either always use a task sequence or always first acquire the transport. Otherwise, if the transport is acquired but the tasks are given out individually, a task sequence from a different section where the transport was not acquire could still interrupt those individual tasks.

Something like Load -> Task Sequence X -> Unload would be possible. So decide which approach you like better personally (acquire resource or use task sequences) and apply it everywhere. Doing both should not do any harm, as long as the order is always the same, but would be redundant.

So it should be like this, to avoid any mixup:

mlall - teste.fsm

[moehlmann_fe]

Yes, the transport seems to always get acquired now.
