sbRIO (cRIO) reboots into safe mode (software error)

[wilburwu]

Hi there,

I've used the sbRIO-9612 for year on the project, recently it sometimes reboots into safe mode. In MAX I may find the status of the sbRIO is "Safe Mode with software error". Can anyone tell me, how can I find out where is the problem. I have the error log as attachment.

Regards,

Wilbur

Hi,

I read again the log file. There're something that should help:

Here is the program for controlling the serial port on sbRIO.

(The missing subVI is used to build up the frame for communication. The wait until 3ms was added according to specification of the component, which the serial controls.)

Can it be a software mistake for the controlling of the RS232 serial interface?

Hello,

please follow the instructions in the manual “Getting Started with CompactRIO and LabVIEW” to reinstall the software on your NI sbRIO-9612.
It’s explained in detail in the chapter “Installing Software on and Configuring the Controller” on page 6

Hi,

here is how I did to solve the problem:

I replaced all the timed loops in sbRIO with the while loops (time interval inclusive)

And that's it! It looks like the timed loop cause the problem in some unknown way. The same thing I've also seen on the FPGA. 

My LabVIEW is 8.6 and NI RIO is 3.1.

Hi, Wilburwn

I have a PXI RT target, and I also use timed loop for determining application. I recieved the same error as you.Do you have any other method for repairing this problem except removing all timed loop? Because I really need the timed-loop.

Best regards,

I had this issue. I found out my problem was I installed lots of software on the cRio and was running out of memory. Once I installed only what I needed, everything worked just fine.
