Customers occasionally encounter the following error message when using the AlarmList widget on their T80 panel display. ERROR: Binding for property mpLink missing! { WidgetId: AlarmList1, ContentId: ContentAlarmsPage }
I think I have seen it before..what version of mappView and PPT image is used on this panel?
Hallo,
Thanks for responding.
T80 panel Image Version is 1.7.0 and MappView 5.24.2 (or older)
Hm, quite new versions are used. Is this an occasional issue? So usually alarm list works properly? Last time, I thought it was an application issue. The visualization had a bad design, with a lot of widgets loaded at once (a tab widget was used for page switching), and this caused problems with hardware performance. After the visualization redesign, the problem was fixed. I do not know your application, so hard to say,but you can:
- update MV to latest version
- check MV performance guides
otherwise you will need get in contact with support of your local B&R office
Hallo,
Happens very rarely at random customers. As you can see the ContentAlarmsPage holds a small amount of widgets.
OK. The cause can be different. I just shared with you my experience from the past. Maybe you can track CPU and memory usage of T80 and also check if the problem relates to the amount of alarms. If you have a lot of alarms and you switch pages quickly,…just thinking.
I think an automatic test can be developed for that. Just an idea… what to do next. I do not think that the Community can help you; this is more for B&R support.
