Finding out the IP Address of a sbRIO

[ajinkya007]

Hello Friends,

I have a problem finding out the IP-Address of a sbRIO-9627. I have forgotten the IP-Address which I configured months ago. Now I want to connect with the sbRIO, but I can't. Is there any way to find out the configured IP-Address ?

Thanks in advance. 🙂

Hmmm, besides consulting a document that contains the assigned static IP address?  I can't think of any.  Well, besides manually trying every possible address.  I'm not familiar with sbRIO.  Is there a button you can press to reset it to a default value?

Very good suggestion, from the sbRIO-9627 manual:

Hi Jens,

thanks for your suggestion. I already tried with the Reset button. Although I am able to change the mode (observed the LEDs blinking), the IP-Address doesn't seem to reset. I still can't detect the sbRIO in NI-MAX.

PS: IP-address setting on my PC is in Automatic mode.

Did you perform the restart twice (first ->safe mode; second from safe mode -> safe mode and reset network).

Next suggestion: log the console output

Hi,

what you could do is connect it to a router/switch (e.g. Fritzbox or similar) and look into the configuration page of the switch and see what is  attached to the switch and whch IPadress it has.

If MAX can't find it, that suggests that MAX cannot "see" it.

How do you connect with your sbRIO?  You need an Ethernet Cable connecting the RIO with an Ethernet Port on your computer, either directly (single cable, possibly a "cross-over" cable, unless the sbRIO is clever enough to figure out whether to switch the lines around or not) or by plugging the sbRIO into the same network as the Computer.

When I've used such devices, I've always used a dedicated TCP/IP port on my PC that is not plugged into the local network.  I usually use an inexpensive Ethernet Switch to handle the crossover issues for me, and plug one cable from PC to Switch, and another cable from Switch to RIO.  I also use "non-routable" IPs for these lines, either the 169.x.x.x, the 192.168.x., or the 10.x.x.x addresses.

There is a routine called "Find Systems" on the System Configuration Palette that should find your device, provided it is on the same sub-net as your PC's Ethernet port.  Find it and write a little test routine, giving it one of the addresses in the sub-net you think you might have used.  See if that helps you find your "lost sbRIO".

Adding to what the other posters have said, I have an alternative troubleshooting step.

I had similar problems on a company network once, where resetting the sbRIO IP address did not help. Turns out, some sbRIOs reset their IP address to 0.0.0.0, which was already assigned for us and/or the firewall didn't like (can't remember). You can check the IP address by enabling console out and using PuTTY. See the sbRIO user manual for instructions - you'll have to restart the device to get it to show the IP. From there, hopefully you can work out if you have a firewall issue by trying to ping it etc.

What you don't want to see:

To solve that one, we had to connect the sbRIO to a computer that was not on the company network/firewall so we could find it in MAX and change the sbRIO IP to something different.
