PI Server egress quick start

Data egress provides a mechanism to transfer data to PI Server using Open Message Format (OMF) messages through a PI Web API endpoint. To get started sending data stored in Edge Data Store (EDS) to a PI Server, create a PI Web API OMF endpoint and configure periodic egress to use the PI Web API endpoint.

Create a PI Web API OMF endpoint

To create a PI Web API OMF endpoint:

1. Install PI Web API and enable the Open Message Format (OMF) Services feature.

   • During configuration, choose an AF database and PI Data Archive where metadata and data will be stored.

   • The account used in an egress configuration needs permissions to create AF elements, element templates, and PI points.

2. Configure PI Web API to use Basic authentication.

   For complete steps, as well as best practices and recommendations, see the PI Web API User Guide.

   Note: The certificate used by PI Web API must be trusted by the device running EDS, otherwise the egress configuration ValidateEndpointCertificate property needs to be set to false, which can be the case with a self-signed certificate, but should only be used for testing purposes.

Create a periodic egress configuration

To configure periodic egress for the PI Server, follow the steps in Configure periodic data egress.
