800xA HMI 5.1 with AC450 Controllers - 800XA HMI False Alarm, Unable to Acknowledged



Alarm appeared in HMI mentioned CPU1 Defect. However after checking at Control Builder A, no alarm in the controller diagnostic page. Try to reset the alarm at HMI but not possible, the alarm still coming.
Alarm "33CRC30BA008_XM11" = CPU1 Defect
In AC450 = No Alarm
Plant Explorer = Got Alarm
OWS = Got Alarm
Alarm unable to clear after acknowledge.
Wondering why AC450 database doesn't has any alarm but in HMI appeared this alarm. Appreciate your kind assistant on this matter.

Are you running an early version of 5.1?
Please read about the known problem (800xAADM-OL-5101-005) affecting Repeat Fail Control and the DI object type in subsequent release notes, e.g. 2PAA114364-510. This problem has been corrected in 5.1 RevD and later versions.
