Hi  
I try to bind a tag alarm enabled to a check box to trigger Disable/enable but I get error of mismatch type.  
The tag is udt withing path;  
PT5201/PV/Alarms/HiHi.Enable  
I also try script to do it:  
system.tag.writeBlocking([“PT5201/PV/Alarms/HiHi.Enable”],[False])  
with no success. Both method worked in 7.9.10.  
Can someone tell how to Disable/enable alarm?  
Specially with binding.

Hi,  
I think you are looking for the wrong property,  
you may find your answer here:

> [@"tag".AlarmEvalEnabled Status within a Tag Folder](http://forum.inductiveautomation.com/t/tag-alarmevalenabled-status-within-a-tag-folder/32799):
>
> Greetings, I need to check is any “tag”.AlarmEvalEnabled is FALSE within a tag folder. When the .AlarmEvalEnabled of any tag within the tag folder is set to FALSE, it should return a value of 1. Does anyone know how to do it?

Hi  
No that’s not what I mean. I need user disable and enable individual alarm of alarms of a tag.  
Each tag can have several alarms and I want to disable it.  
I can read them easily but write command doesn’t work in v8

I want to not to use tag to able enable and disable alarm. For each analog tag have 4 level of alarm for that I had to define 4 additional tag to enable and disable it which cause more memory & CPU usage.  
Directly change the attribute value is more better option.
