the Expression box, with the cursor between the parentheses. Next, type
“*”
to
return a count of all alarms that are in the same location (area) as the HMI server
and are in the In Alarm and Unacknowledged state. Next, move the cursor to the
right of the closing parenthesis.
To count the number of instances of a specific alarm, you can type a tag name
instead of the asterisk.
To include alarms from other areas, use the absolute path syntax. For example,
(“/AreaName::*”).
