Hello Everyone, i have a specific Question regarding the Packml States . If the Unit transitions to the Stopping state, and the corresponding Equipment Module (EM) also enters Stopping, what should be the course of action if an error occurs during this transition at the EM? According to the Standard we have to move to Aborting on the Unit .but we dont want the unit to go into Aborting which would cancel the complete Batch. 

what we want is to move the Unit to the Held state instead of Aborted.  Furthermore, upon resolving the fault, we would like to transition from Held to Unheld, and then return to the exact state from which we entered Held ( instead of the Standard execution state)—in this case, back to Stopping.  this is not possible in the standard though i think. 
does anyone have an idea what can be done here ?

Split from Programming structure.

A split into Units, EMs and so on is quite arbitrary. And each EM can live in its own Unit.
