Stream data from openHistorian 2 to openEca for data analytics

Hello Sir,

Due to the COVID-19 pandemic I don’t have access to my laboratory, however I have some archived data in openHistorian 2. My question is that can openECA stream the data from openHistorian 2 as if it was coming from a data stream.

This should be possible. First I would establish a real-time stream subscription from openHistorian to openECA. Then you can adjust the subscription with startTimeConstraint and stopTimeConstraint connection string parameters which will stream history.

I would upgrade to latest openHistorian release since this version automatically adds a temporal reader adapter to handle requests for history over GEP/STTP.
