The event level setting file contains incorrect or corrupted data. This error is detected at power-on or during a Controller reset, resulting in a major fault that stops the user program and Controller operation.
Click steps to track your progress.
Perform a Memory All Clear operation on the Controller and then re-transfer the event level setting file from Sysmac Studio.
If the error persists after re-transferring the event level settings, replace the CPU Unit.
