Hello,
I am using the .NET based OPC UA Client/Server SDK Bundle v2.2.1 with the included UA Demo Server and UA Expert.
When I want to see History Event of the NotifierWithHistory Node in the Demo/002_History Folder, UA Expert returns me 2 errors :
"Get stepped property of Node [...] fialed with status code BadNoMatch"
"Added Items does not support historizing"
However the NotifierWithHistory Object EventNotifier attribute has HistoryRead and HistoryUpdate set
What should I do to be able to read and write history of Events ?
Regards.
History Event

Re: History Event
Your issue seems to be an user error or some misunderstanding.
The HistoryView in the UaExpert can display history of variables only. What you try to do is dropping an "Object" into the view which will not work, because the view is designed for variables with history only. Dropping notifier objects makes no sense in that view.
The notifier is an object that has history of events. Displaying those events is not currently supported in the UaExpert.
