I understand that in late 2016 a PI connector for OPC UA DA and HA has been released. However is there any interface existing or planned so PI can act as an OPC UA HDA client?
Thank you for any response in advance.
Unfortunately, there are no interface that supports OPC UA. The only appplication that will connect to the OPC UA for data collection at this time is the PI Connector for OPC UA.
You referenced the UA Connector we offer.
Did you mean to ask if there are any plans to make the PI DA act as an OPC UA Server, so you can use an OPC UA client to access it?
Sorry I do understand your question and want to confirm.
Thank you for your interest on this matter. I wish to know if there are any options for PI to act as OPC UA Client while it supports HDA for historical data retrieval. The idea is that PI connects to an existing SCADA Server acting as OPC UA Server. As far as I understand, the HDA functionality is not yet available for PI.
Please correct me if I am wrong.
@Jesse. Thanks a lot for your contribution too.
The connector supports historical recovery - but it isn't fully fledged HDA - it's there mainly for data recovery in case of some accident. The Connector will recover when it restarts back to the time it stopped.
There are no plans to include "User customizable" historical data access at the moment
