When to use an event frames or batch

Batch provides you with a means to generate batch event data based on PI tags. Event frames provide you with a way to track and analyze process and business data related to events that are defined on PI AF attributes.

Different companies and users come from different levels of PI System implementation and use of PI System features; hence, the recommendation of whether to choose batch or event frames is highly subjective. However, as a general recommendation, all customers should migrate to event frames in the near future. Here are a few examples of scenarios that customers may find themselves in:

• You are a batch user and use RtReports.

• Since RtReports 4.1 now supports AF and event frames, you should run the 'Batch To Event Frames' migration, and then migrate your RtReport templates to utilize AF contexts.

• You do not currently use Batch but have batch use-cases or must use RtReports.

• Event frames are recommended. Event frames will support all your needs!

• You do not use Batch and do not have batch use-cases.

• You must use event frames. Typical event frame use-cases include downtime or outages in power industries, excursions in water utility industries, and so on.

  Note: Do not run dual or parallel instances of Batch and event frame interfaces in production as it adds to your migration complexity.
