Solution
The error is expected in LabVIEW 64-bit since OPC communication using Datasocket is supported only in LabVIEW 32-bit version.
- Check the bitness of the LabVIEW you are currently using
- Download the 32-bit version of LabVIEW if you currently are using 64-bit
If you are getting this error also using LabVIEW 32-bit, you should check privileges to read from the OPC Server you are trying to connect to.
