Hello.

ReadMultipleValues strips out the status code and timestamp.
Use ReadMultiple instead.

Example: opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...20nodes%20or%20attributes.html .

You then extract .Timestamp or .StatusCode from the UAAttributeDataResult.

Best regards

Dear all,

I am trying to read OPC UA Variables on my OPC server using ReadMultipleValues and Read functions of TEasyUAClient. How can I get simultaneously ItemQuality and TimeStamp? I appreciate any idea. I have attached part of the code.

Best regards,
Moien
