Upgrade EVT interfaces to PI batch interfaces, version 4.0, or later.
The PI interface for Batch Event File Monitor, V 3.8.7.0, or earlier, cannot write to event frames, so you must upgrade if you want to populate batch information into event frames.
If you require EVT files as a data source, you might be able to use a batch interface that handles EVT files and can write to event frames. All version 3.x interfaces can write to event frames. The following version 3.x Batch interfaces can read EVT files as a data source:
-
Emerson DeltaV Batch (EMDVB) Interface
-
Rockwell Factory Talk Batch (FTBInt) Interface
-
GE iBatch Batch (GEIB) Interface
-
Honeywell TotalPlant Batch (HWTPB) Interface
If you want to use a different interface, you must upgrade it to version 4.0, or later.
See the Knowledge Base article: Migration from Batch Event File (EVT) Interface to Batch Interface Framework, DeltaV Batch Interface, or RtReports.
When a batch interface version 4.0 is running and you initiate migration, the following actions occur:
-
The migration process takes existing batches and writes them to event frames using templates in the OSIBatchMigration category.
-
The interface detects that the Batch Database is locked and switches to generating event frames. It writes any currently running batches to event frames using templates in the OSIBatch category.
-
The interface then loads any EVT files in the source folder that fall within the ABTO (abandoned batch time out) range into its cache. The interface reprocesses these batches to event frames using the OSIBatch templates.
-
From that point forward, the interface writes new batches to event frames using the OSIBatch category templates.
If you have batch applications you have customized in-house, be aware that with PI batch interfaces, version 4.0, PI Batch Properties might reside at different levels in event frames. Refer to your interface documentation for details about where these properties will be located. Consequently, you might need to upgrade any dependent client applications and reports to use the PI batch data created by these newer interfaces.
Note: The migration process will migrate existing EVT Interface data, but only PI batch interfaces, version 4.0, or later, support automatically switching from the PI Batch Database to event frames, after migration.
