Send items to compaction and stock

Hello, thanks for read. I have a problem when I need to send all items from queue to other queue (storage for other activities), I don't know reason but operator send nothing, it make animation but it doesn't move nothing, I probe with four items, in other words when queue 1 arrive four items, operator send to second queue. I attach graphic and model. Thanks for your attention :)

@Ferny Alexis GNA,

I'm not sure exactly what is happening in your model but one thing I did notice that is probably a problem. In your Station1 area the Load PF block is trying to load item (/Plaza Restante 1/Pallet1) to operator 1 (/Plaza Restante 1). When you look at the token labels, you can see that that item is already loaded into operator1. So you're trying to load an item that is already loaded into the operator.

If you could give more specifics about the model time and the objects that are involved in your problem, we may be able to add additional help.

Thanks.

Thanks for your answer, I need to specific item (label type 1), in the real model is paperboard, In real model is necessary to compact, for these reason I need send to first queue to second queue and then compact and created a new product. I attached graphic, sorry for my English.

Let's list the errors so far:

  1. At reset there's an event triggered source activity that doens't have a reference object so that prints an exception
  2. At time 256.422 there's an WaitForEvent activity that fires and prints an exception because it has the option"override return value" checked and the finish activity doesn't specify a return value
  3. Also at ttime 256.422 a token enters the Change Visual which references token.item, but that token only has MyItem label - and is missing item - so another exception is printed.

I stopped at this point as I think you can fix these and then look for more.

I've attach a version of the model which consolidates all the Plaza Restantes into one flow - it's simpler to manage and reduces errors introduced by changing the flow logic for each operator. So in this case it uses a label 'DP' on each operator to know which DP event to listen for. Then everywhere else in that flow the operator can be referred to as current. I added RPs 1-9 as member instances of that flow - in your model you'd got some missing, along with swapping DP/RP numbers (eg. 4 and 7)

If you progress further with this and get stuck - either come back to this post or create a new one and tell us what is happening and at what timestamp, what you expect to happen along with any errors you see. The errors in the console are there to alert you to the fact that somethning is wrong. That's why it's dangerous to accept that the source message about an 'Invald Triggering event' is normal - you can get in the habit of ignoring the messages and before long you have a model that is non-functioning.

thanks for your help!!!, I am trying to solve these problems, but I have a problem with a label when system try to delete with destroy object, I think that there are other label (items) that i don't delete, could you help me please?

Also, Sometimes my "operator" take "product" but it is nothing and my batch plus one, this part you transform in only one system, this is very cool!!! Thank you.
