Reference a label set by scheduled source using inter-arrival

labelissue.fsm

I am setting labels using a schedule source, shown in the 1st image. The first arrival sets a label of "1" and the second arrival at 3600 seconds sets the label as "2". What I want to do is then run a mini assembly line that runs on a 10 second cycle time, which I show in the second image. The issue I am trying to figure out is how can I reference the labels set by the schedule source on my assembly line? I have the assembly line pulling from the list that is populated with the labeled tokens, but the labels are not retained in the assembly line.

Add the label as a field to the list and use the

 SELECT mylabel

clause in the pull to get the label transferred.

Or, just refer to the label using

 token.pulled.mylabel

Hi Jason, thank you for your reply. Where do I enter these clauses?

The first goes into the Pull Activity's "Query/Object/Array" field.

The second can be anywhere you need the value - as long as you still have the original token (ie it's not been destroyed by a sink).


Note on destroyed tokens: the need to manage their persistence is why I often prefer to represent objects in 3D and have the labels there - only when there is an abstract/information requirement (like an order) do I manage the tokens through the lifetime of the abstract item. To me the token is just an indicator of the state of a process invocation - once that process is over, the invocation record(s) should no longer be needed.
