Scott Hillman is Honeywell's Manager Marketing Safety Systems. Like many Honeywell managers, he's not based in the US anymore. Scott is based in The Netherlands. Scott and I speak the same language very well, and we agree on lots of important things.
I asked him about the basic conflicts in Safety Systems: the integrated safety instrumented system argument, the "unclarity" of IEC 61511, and, in the USA, the difference between S84 and 61511-- the grandfather clause.
Scott stopped me in my tracks when he said, if you don't include fire and gas safety, how integrated is that?
But see, Honeywell is the only people who can do that...integrate security, fire and gas, and process safety into the same control system. So, he would say something like that.
It is an interesting question, though, for the other automation suppliers who are promoting an integrated approach to safety.
Hmmmm?
