Hello Zacharia,
It sounds like you would be interested in
NI-DAQmx OPC Capabilities. If you have LabVIEW 8.0 it's very easily done with the Network-Published Shared Variable.
The requirements to use NI-DAQmx OPC Capabilities are a hardware board that uses NI-DAQmx, which you can find using the
NI-DAQ Driver Support page or by talking with one of
NI's Sales Reps.
If this does not completely answer your question, post again and we'll try to help out further.
Regards,
