Hi ank_gup,
Why do you need to use OPC and DSC to communicate with the DAQ card? Which DAQ card are you using? I realize you don't have LabVIEW 8, which version of LabVIEW DSC do you have?
If you need to use the DAQ OPC server, then you need to create virtual channels for the DAQ card in MAX, then you will see those channels in LabVIEW when you want to bind shared variables to the channels.
