Watchdog timout errors on NI-7356 (-70035 NIMC_watchdogTimoutError)

[WouterVleugels]

Hi,

I have a test setup based on a NI-7356 controller. It controls 6-axis, performs contouring and high speed capture.

I have two types of watchdog errors:

1. The computer has to be cold started twice before the controller works. The first startup results in a watchdog timeout error making it unusable without a new cold start.

2. Random watchdog errors (-70035 NIMC_watchdogTimoutError) occur when running the program. They usually occur on completion of a simple move or while intermediately halting a move. This can happen with or without high speed capture/contouring. These errors require a reset of the controller (no power cycling).

I already reduced the number of calls to the controller (e.g. checking for motion complete every 50ms or more, updating contour buffers every 200ms, reading high speed capture buffers every 200ms) so it doesn't get flooded.

Any ideas why this is happening? How can I solve this?

Kind regards,

Wouter

The second problem seems to be solved for now. There seems to be a (driver?) issue when clearing multiple high speed capture buffers in quick succession causing random watchdog timeout errors. By adding time delays before and after the clear buffers command, the program seems to be more stable. A dirty solution though... .

No solution for the first problem yet ... .

Hello Wouter,

Which OS are you using?

Do you have the possibility to test it on another PC? (with different OS)

Can you post the following 2 reports?

Hello Thierry,

I'm using Win7. I do not have the possibility to test on another system/OS.

I've attached the requested reports. Thank you for taking the time to look into this.

Best regards,

Wouter

Hello Wouter,

Do you have the possibility to test it in a different PCI-slot?

Can you specify the exact error you get? (eg. screenshot)

Is this error -70035 and do you see a red exclamation mark next to it?

Would it be a possibility to do a driver (and corresponding firmware) update?

Hi Thierry,

I tried a different PCI slot but it didn't solve the problem.

Drivers and firmware are the most recent ones.

I've attached a screenshot of the (startup) error.

Best regards,

Hello Wouter, 

Then it's either related to the card (HW side or software configuration) or to the pc itself.

One thing we for sure need to check is if the shutdown feature is disabled of your card (check http://www.ni.com/pdf/manuals/371060b.pdf )
