Data Access View has different data than Attributes tab
Posted: 08 Dec 2022, 18:26
Hello,
I am implementing a simple OPC UA server that reads nodes from another server and sends this data to an OPCUA client, e.g, UaExpert. I have implemented my own readValues, writeValues and other required functionalities to read and view data from an OPC UA node. But in UaExpert, while the data shown in Attributes tab is consistent, the data shown in the Data Access View does not have Value and Datatype (NULL). The timestamps are also not consistent with the timestamps shown in the Attributes tab. Could someone give me some hints on this issue? Which function is actually called to get data and show it in the Data Access View and I drag and drop a node onto it?
Here is the picture of the screen.
