Hi @Stefan_Ruttimann ,
Could you please tell us which AS and mapp View version version are you using?
too many alarms are in the history loading of the content takes a lot of time
more or less how many alarms are we talking about? 100/500…
Which hw do you have?
======
I’m learning mappView, could you check if we have a filter available for AlarmHistory widget too? maybe you can filter based on time same we have for AlarmList:
AlarmList and fixed filters? - Ask Questions / HMI & Visualization - B&R Community
Ciao
