Error 6 occured at Write File+(string)

[colsen]

Running a standard compact field point setup with voltage inputs and current output modules.
Our application requires that the system go for days at a time running a data acquisition (200ms)/data log (30sec) loop. After approx 7 days of running straight we get the error below that reoccurs after hitting 'continue':

Error 6 occured at Write File+(string):
Write File
Possible reasons:
Labview Genereic I/O error.
NI-488: I/O operation aborted

We can get rid of the error by rebooting machine and restarting labview. Then it will run again for approx 7 days before having the same error appear.

Any thoughts would be appreciated.
Thanks

Hi,

I think that it would be very helpful if you could post your code.

Thanks,

I'm having the same error code and it screwed up our testing. The system has been running fine for the last 3 months and the error code came up recently. It is recording 5 files in a circular fashion. Each file has 1000000 bytes limit. The error happened so randomly. Sometimes the file is only 100KB, sometimes 300KB and yet sometimes 900KB. When the error occurs, the system effectly froze for a little bit (the software is running at 125Hz rate, so does the file operation. I'll try to write the file in big chunks instead of every loop and see what happens).

We'are using cFP 2010 with 2 pwm output, and 1 current input.

We have investigated this issue further and are now convinced it is a Windows OS issue related to the installation of Norton Anti-virus v7 or 8. This was confirmed by noting system event errors logged on Windows at the same time as the Labview errors occured.

Our application is running on a compact fieldPoint and does not communicate with the desktop, in fact it is in the car. The car is driven around about 16 hours a day and everyday for the past 3 months and will be in the next 3-6 months.

Hi,

Often times these strange issues can be resolved by formatting the compact flash of the controller. There is a KnowledgeBase that describes how to do this. Go ahead and follow the steps, and let me know if you are unable to get the issue resolved. The Knowledge Base can be found here:

I hope this helps, and have a Great Day!

George, thanks for your suggestion. Can NI come out with a rock solid compact fieldpoint system?

Hi,

They are very rock solid...:) They just need some upkeep as with any other system. Think about how often you defrag your hard drive, or even re-image it. Same idea.

Have a Great Day!

Yes, a lot of things need to be cleaned up once in a while. I had expected the RT to be more solid than it is.

Well, the RT system has options to boot into safe mode and maybe other modes as well. How about implementing a defrag mode? I defrag my computer without the need to reinstall everything.
