PI Connector and OPC UA Security

In the last OPC UA blog post I wrote, Migrating from OPC DA to OPC UA, Roger Palmen mentioned the 'security and management puzzle' that many have used as a reason to delay the move from OPC DA to OPC UA. Hopefully, this helps clarify a few things. Also, from my experience, setting up an OPC UA connection is much simpler than configuring DCOM and… (Show more Show less)

Securing PI Web API with a CA issued certificate

Some recent experiences with using the PI Web API highlighted to me the benefits of using CA issued (read non self-signed) SSL certificates, even on a development system.
