ibfind returns a handle even if no instrument is attached.

If I have the power disconnected at my instruments the call to ibfind() still finds a device handle. Is this correct? I would think the handle would return some sort of error or 0.

Hello x33,

ibfind() can be used to open to the device or board you wish to use.  Are you trying to open the GPIB device (instrument) or GPIB board?  If you open the board, it will find the board handle since your GPIB board is still connected.  Can you the section of your code where this occurs?

Have a great day.
