Hi,
I have to define a DeltaV System and I am struggling 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 greatly 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 related group where I can post my questions it would be also great.
Thanks,
Oren
