Receiving Error - 66450

[bill_schieber]

Hello. I revised a LabVIEW project in 2012 to acquire data and control valves from C Series Modules using the cRIO-9082 real-time hardware. I am receiving error -66450  "The NI scan engine cannot perform the requested operation while in fault mode. Clear all major faults and try again." I went into the project Scan Engine and changed the period from default of 10 ms to 25 ms and it appeared to help but I still get the error every once in a while. I don't want to increase the scan engine period any higher then necessary. Could someone offer a suggestion why I am getting this error and how to fix this problem?

Thanks, Bill

Hi Bill,

Interesting issue. Just to ask, is all the dip switches at the cRIO switched off? Were you using some other program, like softmotion, with it? Did it work before using the same hardware configuration?

Thanks

Yes, all dip switched set to Off and I am not using any other software .Thanks, Bill

Hi Bill,

Do you have any other similiar cRIO setups which you can try on? What happens if you try to restart your cRIO and build a simple cRIO RT project? Let's put aside the code which you have revised. Else, maybe you can try to reformat your cRIO and restart it from scratch and see how it goes. 

Warmest regards,
