In a recent Emerson Process Experts blog posting entitled Real-Time Release in Production Recipes Jim Cahill highlighted an Interphex 2012 presentation, Incorporating PAT Methods into Production Recipes for Real Time Release, given by Emerson’s Chris Amstutz and David Rehbein of the Life Sciences industry team. Here’s a video from last year’s Emerson Exchange in Nashville, TN that demonstrates the Syncade operations management software in providing the recipe authoring, recipe management, and recipe execution above the control system. PAT Data Management systems such as synTQ provide the PAT methods and orchestrations and the associated data management.
The PAT methods are treated like phases in the control system and sequenced with the Syncade recipe authoring tool. This allows the action to be performed without operator intervention—provided the design is such that it looks like what the operators would see if the method was performed manually. This automated approach also helps the RTR effort by having the PAT method results end up in the batch record like all the other analyses. Like process alarms, an alarm would occur if a problem occurs during the execution of the PAT method.
In the video the Recipe execution is initiated in Syncade. The PAT methods (synTQ Orchestrations) are launched based on built in recipe triggers and sequencing. Parameters are passed from Syncade to PAT Methods based on the method requirements. Real-time communication occurs between Syncade, DeltaV and PAT Method during the recipe’s execution. Finally, the PAT method completes and its collected details are incorporated into the executing recipe—the final batch record.
