Hi Mr_Prof,

Since I doubt you want to get the number of alarms with just one click, an automatic update is needed. Calling your script example with a cyclic trigger is not recommended, as it may cause a high load on your system. Since your script does not use screen items and assuming that the two tags used are system-wide tags, the best solution in my opinion would be to use a scheduled task triggered by the system tag @SystemActivationState and an alarm subscription within that task.

As an example, I have created a scheduled task named 'AlarmCounter' with the 'Taggs' trigger configuration and the @SystemActivationState trigger tag mentioned above. This is done because the alarm subscription script only needs to be run when the runtime is started.

For the task event, switch from the function list to the script and add the following line to the global definition:

let alrSub;

The script function itself should look like this:

Hello Mr_Prof

similar to the solution of Stefan also in the Toolbox there is a alarm indicator which acts similar:

Hello Mr_Prof

Yes I used this information also for some indication objects for different alarm classes. So you can use for several tasks.
