Has anyone ran a button script to enable/disable alarms in a specified tag folder? Basically looking to use the checkbox component to enable/disable alarm evaluation for a group of tags under the same tag folder. This is for Perspective btw.

From Ignition Manual  
Applicable Tag Type: OPC, Query, Expression, Derived, Reference, Memory

Manual suggests that an OPC tag can be used such as a Checkbox mapped to an OPC tag, I am also having trouble to have it evaluate as it seems it only takes parameters values to it.

Gonna try a couple more things but wanted to see if you had any progress on this?

Thanks!

> Hi Bharat, To change the value of a parameter within a script, you can write to it using system.tag.writeBlocking(). Here is our manual page on that function: [system.tag.writeBlocking - Ignition User Manual 8.1 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC81/system.tag.writeBlocking)

You can directly write to the properties of tags including Alarm Eval. Expand the Tag in the Tag Browser, and right-click the specific property to copy the path. Then try writing to it as you'd expect.

Tagpath example: _[default]Inventory.AlarmEvalEnabled_

You can then write/read it as you would a tag.

For example `system.tag.writeBlocking(["[default]Inventory.AlarmEvalEnabled"], [0])`

If using a UDT, you could also add a parameter and link it, but that isn't necessary to just write to a group of tags and update their properties.
