Retrieve number of active alarms by Cat and Plant Area (ControlSt-Cimplicity)

Hi All,

this is my first post and I would like to thank you for welcoming me.
I am using ToolboxST v7 and Cimplicity 8.2.

For our project, I have created a list of alarms and then I have assigned to each alarm a category and also a plant area.
I need now to retrieve the number of active alarms by category and plant area but, I cannot find a specific intrinsic signal that does the job.

Anyone has done this before?

I thank you in advance for the help
