Blocked subrecipe control
A description of this resolution:
- Observe the handling of operation
Also release subrecipe control TRZPTxx with tool FREE APP when the subrecipe in which a phase was aborted with FREE APP is terminated (xx=01, 02, 03, … etc).
Use tool FREE APP only when absolutely necessary. Operating the recipe via the recipe display (start, restart, stop, termination etc.) should be tried before.
"Blocked subrecipe control" resolves the following:
When aborting phases within a subrecipe with tool FREE APP during recipe run, subrecipe control is not automatically released. The pertaining process unit of this subrecipe remains occupied. New recipes which require this process unit cannot start or will stick.
This behaviour is intended and corresponds to the safety strategy.
Message PROCESS UNIT NOT ALLOCATABLE can be effected if a sequential recipe wants to occupy this process unit (precondition: configured waiting time in instrument requirement).
The underlying cause is:
- Wrong handling
