To meet the challenges outlined above, Avid modified the configuration. This modification moved phase control to the equipment module level.
This allowed operators to start and stop the equipment modules without having to start a phase.
Avid engineers created custom logic to manage the communication between the DeltaV Equipment Module layers and the DeltaV Batch Layer. This change resulted in failure propagation. Failure propagation is not typical when the Batch Executive fails.
The new system allows operators the ability to set recipe parameters at the equipment level in the event of a batch system failure.
When running, the Batch Executive enforces default recipe parameters. This produces consistency in product quality.
The new operator interface now allows the operator can to alternate between running with the batch system or manually. The end result is that the system is set up for the best results possible in either situation. This flexibility allows quick reaction to unforeseen process upsets, reducing any lost production.
