History

The Batch Manager captures all batch processing events and operator activity during the processing of a batch and sends this information to the historical database.

For more information on the data that is stored and the format in which it is stored, see Chapter 11, "History System".

Only one instance of Batch Manager can be active in your batch management system. There are no restrictions on the number of AVEVA Batch Management Runtime Clients that you can have in a system. The Batch Manager interacts with several databases as well as with the clients. The following information describes the interaction of Batch Manager and the databases:

• Master recipes are retrieved from the Recipe Database (RecipeDB) when a batch is initialized.

• The Process Model Database is used to transform the master recipe to a control recipe.

• The Materials Database is used to retrieve the location and tracking IDs of materials that are stored in units. The Materials Database is updated by the Batch Manager when materials are used and produced.

• All batch processing events and operator activity are logged to the History Database.

• The Batch Scheduler manipulates the Batch Database through the Batch Manager. Several Batch Schedulers can be running on a system, but there is only one schedule database.

• The Batch Display is a run-time client application which provides User Interface for operators to select, start, hold, restart, and abort a batch. All information needed to monitor and interact with the process during the processing of a batch is provided.

• The Batch Manager interacts with phase logic (phases) located in the control system. As each phase is to be processed, the Batch Manager checks to see if the phase is ready. If the phase status is ready, any configured phase parameter values are written to the phase, and then the phase is started. When the phase completes its task, it informs the Batch Manager by setting the Done status. The Batch Manager responds by enabling the Reset command and returning the phase to Ready status.
