How do I scan and detect the NI PCI devices present in the system like 4060 DMM and PCI 6511 etc?

Hi there,

I would like to scan the devices present in the system every time when the software starts.

This will help me to prompt user if a particular device is not present or is bearing a different device number than the one used in the software.

For this system I'm using PCI4060, PCI 6511 and DIO96. I am using LV7.0 and Win 2K & XP.

Thanks in advance for your help.

Hi,

you can make a scan of all the Daq devices by using the function: Get DAQ Device Information.vi that you find under the: Traditional Daq - calibration configuration palette.

See BD image attached. It scans for 16 devices and return a list of the found.

This seems to work only for Traditional Daq-compatible devices, no problem for PCI 6511 and DIO96.

I don't know if it works for the multimeter also; if not, you can make a basic call to the device at the beginning of the program and check for errors.

Hi Alberto,

Thanks for your solution. It was useful for acquiring info about DIO96 and DMM4060. It didn't work for 6511. I think the reason could be that the 6511 is configured as a DAQmx device.

Anyone knows how would I do the same for DAQmx device?

Thanx!

Hi again,

for a Daq-Mx device you can get the name by the Daq-Mx property that you can find under the Daq-Mx advanced - system setup. See BD image.

Actually it returns also the serial number, and this may be very interesting for hardware checking.

Hi Alberto,

That was really useful. Only thing is that when I put it into a loop, if the device is not present for a particular dev ID, it returned previous device name. This was able to solve by checking the error.

Thanks a lot for the solutions!

Hello,
Here is another way you could do it, without worrying about getting errors.
