It was brought to my attention this morning that there is a significant discrepancy in how we handle a valve tag as opposed to a damper tag. In actual operation, there is very little difference in how valves and dampers are used. The fluid involved simply changes between the two. (I understand there are air valves, but those are not generally encountered.)
Let’s start by looking at our two current definitions of these tags:
Why aren’t these two definitions more similar? Why does damper suggest a numerical value while valve does not make this assumption? Can a damper not be two-position and be stored in a Boolean value?
To correct these discrepancies, I propose that we modify the definition of damper to read:
“Marker tag on point which indicates a damper used to regulate or control the flow or pressure of air. It is used with cmd to indicate the damper command: true/false (open/close) or 0% to 100%. It may also be used with sensor to indicate a feedback sensor such as a voltage giving exact position between 0% and 100% or open/close as indicated by end-switches.”
I second that change.
Seems like much more thorough language than the original definition. I pushed that change
