Hello
I have alarms that hover around the
setpoint to alarm into our control room.
To keep from having dozens of alarms. I read
we’re the deadband can be configured to assist
with this.
Can someone help explain how the deadband works?
For example if I have a setpoint of 800 and the value
goes up to 800 and alarms in, but drops down to 799.
Resets and goes back to alarm state.
If I set a deadband of 2. What would this do?
Would the tag value have to drop down to 798 to reset/clear?
And would the alarm still alarm in at 800 or does the deadband
affect to top end and the low end of the alarm setpoint?
Just trying to get a good understanding of how the deadband works and how it affects the alarm.
Thanks for helping
