Issue Details

I have a cRIO chassis containing the Functional Safety Module NI-9350. When I am running a LabVIEW code, I receive the following error:
Error -65492 occurred at Shared Variable in>>>

Possible reason(s):

The operation failed because of CRC error. Check the module power supply and reinsert the module.

This error or warning occurred while reading the following Shared Variable:
\\RT<file:///\\RT> CompactRIO Target\Mod8\Var1

Why is this happening and how do I fix this?


This error occurs because the scan engine has been set to an unstable speed (faster than 1kHz). To fix this, right-click the chassis in the LabVIEW project and set the scan engine to be 1ms or slower.
