We need a little more info. How are you using Labview and your OPC Server? Datasocket, Front panel bindings or Project I/O library?
Hello, I'm stuck in reading OPC UA data and I need help, please.
I successfully created an OPC UA server and wrote on it matrix data as you can see in the first picture.
but when it comes to collecting that data. I do not manage to do so as desired.
and I want to get them back to the matrix form
attached in the second picture, the program diagram for the receiving function.
Questions. 1- What is controlling your loop timing for your opc server? 2- Put the current Time stamp in your cluster of data for the "OPC Format" to know when data is acquired. 3-Why are you writing your array of doubles to the OPC server as a variant? If you wrote your data as an array of doubles.
Then you can read your OPC server as an array of doubles. You would need to create a new OPC format cluster for the double type. Then you can save your data to a tdms file as double arrays. Plenty of examples of that.
