My computer recognizes my cRIO 9002 but not the analog input NI 9205

[xavgu]

Hi,

I'm working with a cRIO 9002 unit and a NI 9205 analog input. When I check if my computer recognizes de cRIO in the Measurement & Automation Explorer, everything is correct, I have the cRIO with all his software and ports.

But when I'm trying to use the DAQ-assistant in LabVIEW, I click "Acquiring data ->Analog input ->Voltage -> ..." and it says: "No supported devices found".

I've been looking trough the forum, I've installed all the new versions of software and drivers and I've tryed with real-time or with labView and nothing.

Do you know where is the problem?

Thanks!

Hi xavgu

You will not be able use the DAQ Assistant to acquire data from your cRIO. Trying to do so is like trying to flyfish with a bottle opener, i.e. totally different things.

To get data from the cRIO you first have to program the FPGA to read data from the module and then pass the data to the real time controller, which can either logg the data or in turn send it via TCP/IP to you Windows host. Sadly the 9002 cannot handle Scan Mode, which would have made it easier for you.

Hej Davidek,

Thanks for your answer! I've made a fool of myself!

I'm a begginer and I knew I was doing something wrong but I didn't know what! I will have a look to these getting started and try again with the correct steps!

Thanks again!

Hi Xavgu

If you don't dare to ask you will never get any answers and there is no such thing as a stupied question. So keep asking 🙂

OK!

Thank you for encourage me to continue working. I've managed to create a VI for the FPGA target and another one for the host, but I've a question.

I'm acquiring a signal that I want to use it later. Right now I'm storing the data in a .lvm file with my computer.

Do you now if I can store the data in the cRIO and then take this data in the computer?

I mean, the cRIO is mounted in a motorbike and it's quite difficult to ride the bike with the computer in your backpack!

Thanks again for your help!

Hi Xavgu

You can store data on the RT controler of the cRIO. You only have 64 MBs of storage space on your 9002 (later models have more storage), but if your file is smaller enough you can save it on the controller and then transfer it to your computer via FTP. The cRIO has a built in FTP server, just go to MAX, right-click the controller and select "File Transfer" or use a commercial FTP client. If you need more storage space there is a C-series module that allows you to use SD memory cards to save data to.
