Transporter Unloading problem

pruebas.fsmHi all,

I have one transporter connected to 3 queues, each one with a priority of transportation, my problem is that at some point when the transporter is already loaded with an item and receive a new tasksequence with a higher priority it doesn´t unload the item before going to the requested queue. I tried with the trigger "Unload all items intended for this station before unloading to other stations" with no success.

Thanks in advance for your support.

I can not upload any image or model in my question at the moment, I don´t know why.

Regards

Alejandro

Hi Jeff,

I tried to do that, but for some reason it appears the following error "Error parsing the uploaded file". I will upload it as soon as the system let´s me.

Thanks.

Change your Preemption to "preempt, aborting active" on all your queue being fed by sources. After running for a while it seemed to do what you wanted and stopped picking up multiple items, correctly prioritizing its tasks .

Hi Joshua,

Unfortunately, with the proposed changes still doesn´t unload the item in the proper way. Around second 415 the transporter already has the orange item and before unload it, he goes and load the blue one.

Thanks, I should have run it for longer to see that happen. So using any preempt will cause the operator to stop it's current task even if it is almost done with it and perform another task with a higher priority. You would have to rebuild this polling of tasks via process flow.

Ok, I would create an approach I will share it with you for some feedback. Thanks.
