LabVIEW Implementation of VXI-11 Discovery Protocol

[PPLLC]

Has anyone implemented the VXI-11 discovery protocol using LabVIEW? I know I can use MAX to detect LXI instruments, but I like my code to be able to perform inventory functions independent of MAX. Is there a way to call the discovery routine within MAX from LabVIEW?

Chris,

VISA 4.4.1 supports automatic detection of LXI devices that support the mDNS technologies.  If you have this version of VISA installed, you should be able to use the "VISA Find Resources" node in LabVIEW to find LXI devices.

I tried using TCPIP?*INSTR as my search string, but it doesn't find anything that I haven't defined as a VISA TCPIP resource in MAX.

Hello Chris,

If the device is not registered in MAX, then it will not show up using this method. However, if you know the IP address of the instrument, then you can add it manually. There is no way to have MAX scan for instruments programmatically. Here is a tutorial on LXI.

Thank you,
