Connecting to a Remote cDaq-9132 in NI-MAX/LabVIEW

[nds2123]

Hi all,

I am the proud owner of a small family of cDAQ-9132's. I currently use them for remote monitoring purposes but I have never been able to actually connect them to MAX since, after they are deployed, they are no longer on my company's network. When they are on a client's site, they connect to the internet via Airlink GX450 modems. They run Labview code that writes data to a file, and I use the Web Browser to get onto the machines and download / check the collected data. I would like to make a true mobile connection to LabVIEW (which from what I understand requires connection to MAX).

I have tried (to no success) entering the static IP of the cellular model when prompted in Max: Remote Systems -> Create New -> Remote Device (not on local subnet). The troubleshooting wizard seems to only work with RIO devices.

I'm running Max 17.5 / LabVIEW 14.0 as well as DAQ-mx and Real Time Linux systems. Again, I have no problems connecting when I am either directly connecting my PC to the cDAQ, or when my cDAQ is connected to the same network as the PC.

Depending on what you mean by "true mobile connection to LabVIEW" MAX may or may not be necessary (probably is not necessary).

If you are simply trying to get the data off of  the cDAQ controller, I'd just set up some networked storage and use scp (or maybe NFS or samba) to copy the files onto the network storage using system exec. In this case, NI-MAX is not required but the devices/network will need to be configured in such a way that the cDAQ can access the networked storage.

If you provide a little more detail about what you are trying to accomplish I might be able to get you a more targeted suggestion.

Thank you, Brettski.

Since I am able to SSH and FTP into the cDAQ, I am already able to transfer files. I am more interested in remotely connecting labview for a live connection to the front panel (for looking at sensor levels) and for remote development (currently I am doing this by building and swapping startup files over the web interface).

I would recommend you look into Network-Published Shared Variables.

Remote front panels might also be an option for what you are trying to accomplish but they are more or less deprecated and require MS Silverlight (and therefore Internet Explorer) to run. It's ugly.

If you need to access from outside the network you are going to need to look into tweaking your network. I recommend you explore the possibility of getting a VPN setup. Port forwarding might also be an option.
