I would like to delay my alarms for a brief instance so that I know a signal is real and not a glitch, how could I delay an alarm for a second or two.

I have a flow controller linked to fieldpoint that is tripping my alarm system (in Bridgeview) every time it reads a quick voltage difference. This occurs only for an instance, but it is enough to trip my alarms. I wanted to place in a 1 or 2 second alarm delay to make sure the signal is real, if it is than the alarm can trip. If it lasts for a brief instance I want the system to keep running and the alarm to ignore the glitch. How can I program that?

The way you implement this entirely depends on your vi-code.
An easy solution I could think of would be to low-pass filter your alarm-signals and check these values for limit-increase.

LabVIEW
