Disconnected cDAQ remains on the list of system devices "present"

[abenevides]

I'm trying to implement a whitelisting and system hardware check to our automated test system which utilizes a cDAQ. The issue I'm running into is that, while I can get the cDAQ information via the System Filter and Find Hardware VIs, the cDAQ hardware does not exit the list when the "present" filter is set to "is present."

This does work with the RIGOL oscilloscope I have. It may be worth noting that I'm trying to interface over Ethernet to all of these instruments.

I noticed the cDAQ lists the status as "disconnected" in NI MAX, but there is not option to check this status field in LabView from what I can tell...

Instead of checking that status field, what about running the DAQmx self test on it, since you seem to be able to get a reference to it in LabVIEW?

For TCP/IP, I use "Find Systems" and ask it to only report "only if online".  As an added bonus, this can return the IP(s) and Remote Name(s), which can help you if there are several systems with different names out there.

Thanks Bob, I think this is a good solution to the problem!
