The example takes all of its VIs from LabVIEW’s WebDAV palette, which you can access from the Data Communication palette → Protocols palette → WebDAV palette → WebDAV Synchronous.į igure 2: A demo program that transfers a file from the cRIO to the PC, then deletes the file on the cRIO. Note that this VI runs on the PC, so the transfer is in terms of “getting” the file from the cRIO. A complete example VI is show below in Figure 2. If you’ve been able to connect in Windows, then you should be able to connect programmatically in LabVIEW. If none of this makes sense to you, don’t worry about it, just keep your files in /home/lvuser/natinst/bin until you get it figured out. C/ni-rt/startup is a symbolic link to /home/lvuser/natinst/bin in order to preserve some compatibility with the conventions of older cRIOs. home/lvuser/natinst/bin is where we’ll make files in this example. If you’re familiar with Linux, the hard drive layout will look familiar. Note that you cannot write files anywhere you like on the cRIO’s hard drive.

If this works, then you know WebDAV is working fine on your PC client and your cRIO server. Hit OK, give it another couple seconds, and you should be presented with an Explorer window showing the files on the cRIO’s hard drive.

By default, the username is “admin” and the password is blank.These are the same credentials used to log in to the cRIO over SSH, or in NI-MAX.It will then ask you for a username and password. Don’t forget the “/files” at the end! This isn’t a placeholder for the filename you’re looking for, it is the literal string “/files.”.Uncheck Reconnect at logon, since the cRIO may not always be available.In Windows 7, press Alt to expose the menu bar, then click Tools, then Map Network Drive.In Windows 8, click the Computer menu, then Map Network Drive.So, let’s say the cRIO’s IP address is 192.168.10.200 (and your PC is on a subnet with the cRIO):

Both Windows 7 and 8 have built-in WebDAV clients. If a WebDAV server is running on the cRIO, then you can connect directly in Windows as if it were a traditional network shared directory. You should see SSL Support and WebDAV Server listed, as in Figure 1.įigure 1: A properly-configured cRIO includes SSL Support and the WebDAV Server.Īs long as those are available, you’re already configured. Expand the cRIO, then Software, then NI CompactRIO. To confirm, open NI-MAX, and expand Remote Systems. For this post, I used an NI cRIO-9068.Īs mentioned above, the Linux cRIOs have WebDAV and SSL support enabled by default. This will be a brief post to point out those details. The first time I used it, I noticed a couple pitfalls that are worth documenting. This makes WebDAV an easy option to use right out of the box. There are many ways to do this, but newer Linux-based NI CompactRIOs come with WebDAV and SSL support enabled by default. When using a realtime system for data acquisition or control, there is often a need to transfer files between the real time device and a PC.
