Hi,
to access a remote database on another computer you have to know the abolute path on this other computer and specify a "networked database path" as e.g. "\\computername\driveletter\folder\data"
Here is a basic link on how to do that:
Logging Data to a Remote Citadel DatabaseAs well the online help of Read Historical Trend(s).vi points it out.
Now, I just hope you are using LabVIEW DSC 6.1.
Hope this helps
