Hi, I have to define a DelatV System and I am strugling with a few things. I am trying to figure out the difference between "Interlock" "Shutdown" and "Permissive" of a DC function block. I know TDC very well. If someone could explain it to me in that (Honeywell)language I would grealty appreciate it.
Is there a priority issue between them? It looks like the interlock and shutdown perform the same function. Is that so? Is there a way to interlock the active state(s)? Is there a way to permit the change to any state? or only to the active1 state?
If anyone knows of a DeltaV realted group where I can post my questions it would be also great.
Thanks, Oren
