Link BES to MES batches using event frames

To consolidate the output of a manufacturing execution system (MES) and a batch execution system (BES), specify the linking element as follows:

1. Open PI Event Frames Interface Manager.

2. Select the Batch Setup tab.

3. For MES interfaces, enable the Link to child event frames option, and specify the path to the PI AF element.

4. For BES interfaces, enable the Link from parent event frames option, and specify the path to the same PI AF element.

This configuration is typical in an environment where an MES supervises multiple batch execution systems to manufacture a single product. For each BES, configure a dedicated interface instance and specify the same PI AF linking element.

When an event frame created by the MES interface references the creation of a batch in the BES, a reference is made to the MES event frame in the linking element. Then, when the BES interface creates its event frame, a reference to it is created in the MES event frame, creating a consolidated view of all the related events from different systems.

For example, the following figure illustrates an event frame created based on a batch from an Emerson DeltaV batch execution system. This event frame is referenced in an event frame created by a Werum PAS-X MES. Other batch interface instances that are configured to use the same linking element create references to their batches under the same link.

The .ini file code for creating those event frames resembles this example:
