Using ASRS Vehicle to pick an item out_4.fsmHi, I'm not sure what went wrong but every time I reset, i receive this error:

exception: Executive::__reset()

exception: int Executive::reset()

exception: reset

and when I saved the model, it gives this error:

exception: FlexScript exception: VIEW:/nodefunctions/workspace/saveworkspaceview

exception: FlexScript exception: VIEW:/nodefunctions/workspace/saveworkspacelayer

I'm not getting any errors when I run or save your model. Might be an error that fixes itself on a restart of FlexSim or the PC.

Does the attached model work you?

Hi Felix, that seems like the case. I have another question though. In my set the token.EntryPoint label depending on what the destination is, am I setting the code wrongly as it does not seem to recognise to go to the right entry point.

[moehlmann_fe]

You compare the pointer (object reference) with a string value (which weirdly returns true and thus the EntryPoint is always set to DP1).

I would generally try to avoid using names to reference objects. It makes it more likely that changes to the model such as replacing an object breaks something and also makes scaling up a model much more time consuming. Use 'relative' object references (pointer labels on the racks or port connections) instead.

The method you use to send the item is always prone to errors, because you assume that the first item on the conveyor is the one to be send. If there are ever two or more items on the conveyor the wrong item will be send. The token already has access to the target point, so I don't see a reason to not just send the item in Process Flow.

Thank you for the guidance. I didnt think I could custom code to send the item as well rather than using another DP which like you said can cause errors in the future. Thank you very much!

Hello, I have one more question. Do you know how do I return the asrs back to default location when it's finish its task.

[moehlmann_fe]

You can use the "Travel to a Home Location" or "Travel to x,y,z Location" in the "On Resource Available" trigger of the ASRS.

Hello, I did as what you said. It seems like when it returned to the home location, it keeps trying to get a item in as it constantly goes back and forth the entrytransferUsing ASRS Vehicle to pick an item out_ASRS manual_4.fsm

Yeah, the ASRS is a bit special in this regard. If the destination is offset from the center to either side, the slide will extend to that location and the automatically retract again. This means the ASRS always repeats the travel to the home location since after the slide has retracted it is not there anymore.

You can use the coordinate option instead with values like these. This should work as long as the ASRS is not rotated.
