Which one? In a previous life I worked for Hartmann and Braun as the product manager for the Contronic P and Digimatik DCS systems.
It's a Honeywell Experion / Honeywell TDC 3000 hybrid. It's a pretty good setup. I like the idea of having an experience blend of IT and process controls. I only have 2+ years on this system, I can't wait until I get 5 years. Before this job DCS was a small part of my job, I used to be an Instrument and Control tech, now it's just control, no more tools or field work.
