Continuum Controllers

Cause

The error is a time related error but may not indicate that there is a physical problem with the controllers Real Time Clock (RTC). This can be due to an issue occuring on startup of a controller where there may be requests for time from COV updates. If that request comes in prior to the RTC clock coming up, it can post this error. The COV code will post this error and then try again later. 

Resolution

If this error occurs after a restart of the controller then this is more than likely a benign error and can be ignored. However, if it occurs when the controller hasn’t just restarted then it could be an actual fault with the RTC chip and may need to be returned for repair.
