cRIO 9082 - Cannot connect through NI MAX/LV

[JZaulich]

Hello all,

I'm currently writing my bachelor's thesis on dynamics and testing of vibrations.

As a part of the project I'm designing a experimental platform used to excite certain mechanical components.

As we need several sensors (PZT, accelerometers, DC motors etc.), we're using a cRIO 9082.

However, when i want to connect to the cRIO i cannot see it in NI MAX, i.e. i can't configure it. I can only see it in the NI Browser (see attached picture).

I'm connected directly to the cRIO through a crossover cable and the IPv4 is set to automatically assign the IP adress.

Any ideas of how i connect properly to the cRIO 9082.

I'm new to working with this kind of electronics, since i'm majoring in mechanical engineering - so please keep explanations as simple as possible 😉

If you need more details, please let me know.

Thanks in advance.

JZaulich.

Hi JZaulich.

According to your screenshot from NI Network Browser, your cRIO has been assigned 169.254.173.43 as IP-adress. If your RIO is connected directly to your computer, and you haven't assigned a static IP, that IP is what we expect to get assigned. It is called a Link Local adress; that means, if the controller cannot initiate a DHCP connection, it will connect to the network with a link-local IP address.

Normally you should be able to see your device in MAX, but it can be that you have a firewall blocking, or something similiar. Try to do the following:

1) Right click on 'Remote Systems' and select 'Create New'

2) Choose 'Remote Device (not on the local subnet), and click 'Next'

3) In the IP-adress, type the IP-adress you see in the network browser.

Hopefully, this will add your cRIO system to MAX.

Hey Alex,

Thank you very much for your reply.

I had to disable the Windows firewall as well as the AVG Firewall, which did the trick.

Apparently Windows doesn't allow this type of connection.

After disabling the firewall, i added the cRIO using the IP-adress and it seems to be working fine.

Thanks again.

Best regards,

Hi Jakob.

Great. I'm glad that helped.

Now you can continue working on the fun stuff 🙂
