Emphasize the concept of 2+ trust in 'Configuring a Simple PI System' Online Course
The video "Configure Security for the PI Interface for OPC DA" in the 'Configuring a Simple PI System' course could benefit by reinforcing the fundamental concept of what a 2+ PI trust actually is at a second point in the video.
The first time I watched it, I missed the brief definition near the beginning, and then became rather lost later in the material, until I re-watched it from the beginning and stopped to consider this point. A simple on-screen speech bubble (perhaps at 6:25) clarifying this point would be helpful - the spoken material is ambiguous here and so it's not entirely clear what is actually being communicated.
Kenneth Barber commented
At this point, PI Trusts should be de-emphasized in favour of PI Mappings.
