The next phase in the development of OMF applications is to write the application. The first part of writing the application is setting up structure of the data. This consists of the following steps:

  1. Create OMF type messages to create element templates in PI AF.

  2. Create OMF container messages to create PI points in Data Archive.

  3. Create OMF static data messages to create elements in PI AF based on the element templates created by the type messages.

  4. Create OMF static-to-static data messages to create the hierarchy of elements in PI AF.

  5. Create OMF static-to-dynamic data messages to create PI point data reference attributes.

  6. Once the structure is in place, you can send time-series data. These messages will be the continual stream that you send to Data Archive.

  7. Create OMF dynamic data messages to send time-series data to the PI points created by the container messages.
