Hi All,

Could you please help me with the following issue. 

I tried to read a node in some UA Server. It gets StatusCode as "BadWaitingForInitialData" from my client. But when I added that node to Data Access View in UaExpert(Another Client) it shows Value as "null" and then I tried to read it using my client. Then it shows "null". This happens every time when I go to read that node.

What could be the issue??

Please help me.

Thanks.

When the StatusCode is Bad the value is always NULL.

BadWaitingForInitialData is supposed to be a temporary code as the server establishes its connect to the source of the data. If there is an error getting the data it should BadDeviceFailure or BadOutOfService.

Thanks, Randy for your reply,

After adding node id's to subscription my problem is solved.
