Adding persistance To Alarm specification Page

[Siddharthan]

Hi,

Here is a small idea that will be really value added in Alarm Handling

In cases of using sensors like inclinometer, thermocouples, LVDT and etc, there are chances where noise peaks in signal might go Out Of Limits. These kind of peaks are usual in the sensors where it stays not more than 5 msec. So in these case, We can use Persistance to avoid inducing false alarms. We can ignore the noise peaks whose period is not more than the defined time (mscec).If the peak remains more than the specified time, then the alarm should be induced.

 

The Persistance might be given in msec.The user should also be able to enable/disable this option.

It sounds like what you are describing is what the Delay Duration does. The documentation for the configuration page is a bit vague:

But the VI documentation is more explicit:

This description is indeed delay duration. Please comment if that is not what you are looking for.
