Well, I’m about to show you a similar hidden treasure. has an exclusive online column called OPC Connection. This online column is written by Eric Murphy, a chemical engineer with a process control specialization and an OPC expert. Murphy has been a part of the OPC community since its early beginnings in the mid-1990s and is a member of the  OPC Foundation’s Technical Advisory Council.

Murphy’s latest column is titled “OPC UA Security: Do You Have Reservations?” This article talks about OPC UA security reservations  end users have when they start thinking of adopting this technology. The article also discusses how OPC UA provides the infrastructure for multiple tiers of security implementation. Check out the OPC Connection channel to read this article.

Trans-Domain Technology Proliferation” is another of Murphy’s columns. Here, he gets to the bottom of what the daunting term “trans-domain technology proliferation” really means.
