cRIO interrupted during reimaging

[rsisk]

We were reimaging the cRIO device and our network cable came loose during the "Formatting CompactRIO device..." phase.

After restoring the network link, we can ping the DS (10.0.0.5), but cannot ping the cRIO (10.0.0.2).

On the cRIO the Status light is blinking orange and the power light is green.

Restarting the cRIO imaging tool says that No CompactRIO devices were found. Verify the network connection.

Looking for advice on how to proceed...

Thanks

What exactly does the blinking look like? The pattern can tell you what error the cRIO is encountering.

From the cRIO documentation:

Table 3. Status LED Indications
Number of Flashes Indication
1 The chassis is unconfigured. Use MAX to configure the chassis. Refer
to the Measurement & Automation Explorer Help for information about
configuring the chassis.
2 The chassis has detected an error in its software. This usually occurs
when an attempt to upgrade the software is interrupted. Reinstall
software on the chassis. Refer to the Measurement & Automation
Explorer Help for information about installing software on the chassis.
3 The chassis is in safe mode because the SAFE MODE DIP switch is in
the ON position. Refer to the Configuring DIP Switches section for
information about the Safe Mode DIP switch.
4 The software has crashed twice without rebooting or cycling power
between crashes. This usually occurs when the chassis runs out of
memory. Review your RT VI and check the memory usage. Modify
the VI as necessary to solve the memory usage issue.
Continuous flashing
or solid
The device may be configured for DHCP but unable to get an IP address
because of a problem with the DHCP server. Check the network
connection and try again. If the problem persists, contact National
Instruments.

One thing you could try is to set the IP RESET dip switch to on, and powercycling the cRIO. It should now have the IP 0.0.0.0

From the cRIO documentation:

Push the IP RESET switch to the ON position and reboot the chassis to
reset the IP address to 0.0.0.0. If the chassis is on your local subnet and
the IP RESET switch is in the ON position, the chassis appears in MAX
with IP address 0.0.0.0. You can configure a new IP address for the
chassis in MAX. Refer to the Resetting the Network Configuration of the
cRIO-FRC section for more information about resetting the IP address.
You also can push this switch to the ON position to unlock a chassis that
was previously locked in MAX.

After resetting the IP, try to ping the cRIO. If it responds, see if you can reimage it now.

The flash is continous.

We are trying the Reset IP suggestion...

After the IP Reset, I still get a continous blinking status light.

The ethernet port on the cRIO shows a green light on the 10V/100 side, and a solid orange light on the link side.

Both MAX and the Imaging Tool are unable to find the cRIO.

We are linked to the DS throught ETH2 all lights are green, which is linked to the cRIO through ETH1 with a green light on the DS and the lights on the cRIO described above.

Assuming you changed your team number while re-flashing, you should change your PC's ip address to 10.24.93.6, and then try to ping 10.24.93.2. But that probably won't matter now that you reset the IP address.

[rsisk]

Thanks Eric, just tried that and the request timed out.

[rsisk]

Anyone know if NI provides phone support on Saturdays? And if so, what is the number to call?

[rsisk]

After the IP Reset, the documentation says the IP address is reset to the factory default. I assume this is 10.0.0.2?

[rsisk]

OK, powered down the cRIO, powered it back up and now the orange link light on the cRIO ethernet port is blinking, so I am assuming we have communication taking place. That is a step in the right direction.

The Status light on the cRIO is still doing a slow continous blink.

Still wired from the computer to the DS to the cRIO. We temporarily tried using the crossover cable which also shows blinking orange link led.

a ping of 10.0.0.2 and a ping of 10.24.93.2 (with the computer ip set appropriately) are now returning Destination Host Unreachable

[EHaskins]

Try connecting the cRio and your PC to a router with DHCP enabled. Then check the router DHCP table and see if it got an IP address from DHCP. Its possible when it was reset it changed to DHCP configuration.

You could also connect your PC to the console serial port on the cRio. On about line 30 the IP address/subnet mask information will be displayed.

To do this you need to configure your cRio and PC as described in section 5.4.1 of the control system manual. If you're looking for another terminal client for Windows PuTTY is what I'm using.
