Just curious. If you got a control description that described analog alarms in some detail, BUT did not state whether the alarm was activated
when the parameter was > the setpoint, or >= setpoint (for high alarms), would you either:
a) assume its PV > SP
b) assume its PV >= SP
c) ask for clarification (the right answer of course)
In the real world, most of us would probably pick either (a) or (b) and the customer would decide that our 300 alarms are all wrong because they
think it should be the other way, of course only telling us this after its complete and ready to ship (or better yet after its in the field and
running).
