An AutomatedBuildings.com interview with Tom Burke of the OPC Foundation and Sean Leonard of Matrikon.
The interesting thing to me is how similar building automation is to industrial automation, yet how "stove piped" their respective products have been. Even the protocols, Leonard mentions "BACnet, Johnson Controls, and LonWorks", are totally different.
The interview rolls the grandiose OPC UA ambition into our sister industries, in addition to the direction you're used to, "up", namely Enterprise Integration. It focuses on OPC campaigning, providing interesting insight on what The Foundation is focusing on.
Good to see things moving forward. Early OPC UA buy in is going to be important.
