We have posted the Q&A document from last week's webinar on CIP Version 4 here. There were a lot of good questions, and I can assure you that the Honeywell/EnergySec team had a lot of discussions while answering them.
If you would like to listen to the webinar, go here. To download the slides, go here. Because there was a syncing problem between the speakers and the slides in the recording, I recommend you listen to the recording separately, then look at the slides (there are a few slides that we weren't able to address in the webinar, anyway).
