You know the feeling you get when you put your hands between the sofa cushions and discover a dollar bill? How about when you’re doing laundry and find long-forgotten money in a pants pocket? Well, I’m about to show you a similar hidden treasure.
ControlGlobal.com 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. Murphy writes that for some users this sounds more like the latest thing in home theater equipment, but it really best describes what OPC is. Read the article to find out more.
If you’re thinking of implementing an OPC UA security system, read our article “OPC Security: Seven Years, Seven Fears.” This article lists seven security fears that every OPC systems owner should confront before implementing this system. At the same time, the article gives different OPC options that can help sooth your fears. Some of the fears Murphy lists are loss of obscurity, complacency and fear of the unknown. Read this article to learn about these and the remaining fours fears.
