Create Recipe to Include Allocate and Deallocate

Sepasoft MES Module Suite

Batch Recipe with Custom Parameters

The Allocate and Deallocate Phases are used to control allocation of shared Units. An example of a shared Unit is a heater that is used by multiple Mixer Units. When a Mixer Unit needs heat, it can allocate the heater by using the Allocate Phase. When it is done with the heat, it can deallocate it using the Deallocate Phase making it available to other Units to use the heater.

#CREATE RECIPE INCLUDING ALLOCATE AND DEALLOCATE
#It allocates the shared unit "Enterprise\Site\Area\Process Cell\Shared Unit"
#It will wait unitil it can allocate the shared unit and then delay 30 seconds. Once the delay is done,
#it will deallocate the shared unit "Enterprise\Site\Area\Process Cell\Shared Unit"
