I have to confess I get somewhat disturbed when I think of someone who cannot understand a car battery working on SCADA and power production sub-systems but protocol converters are going to have a place in the arena. His post (hell the entire blog) is a transparent plug for his company (not that that is new [except here of course where I religiously avoid companies I do or have worked for]) but that is alright. My message to you guys.
Show Me the SECURITY!!!
Could be there I just want to see it.
