My scenario is I have 1000 tags that have alarms, and I want to filter out the alarm status table to show only a subset.

By user they are interested in a subset of those tags (like 200 out of the 1000). There's no naming convention to the tags that I can use as a wild card. But using a database query I can create a dataset of the respective subset.

Is there a way to filter the Alarm Status Table using a dataset?

You could use the `filterAlarm` extension function on the alarm status table scripts.

Each alarm will run that script, if you're using a dataset, you could loop through that dataset. If the tags is found in the dataset return `True` or if not `False`.

I was able to figure it out using the filter / condition property. It takes comma separated values.

I had worried a long string would have performance issues, but no issues filtering out a subset of a few hundred.

Thanks for the inputs.
