Description

Osisoft PI is the most used historian in the Oil&Gas industry. EdgeX needs to be capable to ingest data into such a platform. 

Requirements

• Authenticate the edge node through standard OSI PI premises (Basic Authentication at minimum)
• Create new tags in PI Archive
• Edit existing tags in PI Archive
• High throughput data ingestion up to 10k events/second
• Ability to send data to multiple PI Nodes concurrently (up to 3)
• Local buffering and retry mechanism with resilience to network downtime
• Local logging of error messages & events through EdgeX Log service

Design

Two approaches are possible in order to implement this export service:

1. Clone the current EdgeX REST export service and modify it accordingly to send messages to PI Web API
2. Create an ad-hoc OMF connector to send messages to PI Connector Relay with OMF

Code

To be updated.

Current status

In January 2018, based on Osisoft feedback, a decision will be taken on whether to proceed with Option 1 or Option 2
