What is the exact difference between AuditEvent_OperatorAction and AuditEvent_ForcedChange?

We do have different Audit Event Class in Audit Trail. And I got to know when exactly the class AuditEvent_OperatorAction is used but not AuditEvent_ForcedChange. As per description, I forced one object (SignalReal) and gave value on "Man" parameter from faceplate, but in audit list it shows as AuditEvent_OperatorAction. I tried forcing from Control Builder for the same object and gave value to "Man" parameter and the result is same in Audit list. Could any one help me to understand the exact definition / purpose of AuditEvent_ForcedChange class.

Thanks in advance!!

Have you tried Forcing the RealIO or BoolIO Value from the hardware Editor or from the Application Program ?

Yes, I tried forcing of both RealIO and BoolIO value from Application Programs and as well from IO Editor, but still it comes under AuditEvent_OperatorAction.

An AuditEvent_OperatorAction is emitted for each time* an OPC write passes through System 800xA. Forcing an AC 800M signal is made via writing an OPC property.


*) Writes made from the 800xA Service account is exempted from audit.


I would expect Control Builder M Professional to use direct MMS communication when online with a CPU and issuing a forcing (which should be like changing any property). Maybe the programmer of CBM elected AuditEvent_OperatorAction as category of audit to mimic OPC writes posted from the HMI.


I cannot tell what AuditEvent_ForcedChange is used for, System 800xA is large and there could be other meanings of "forcing".

Thanks for your response Mr.Stefan. I checked as per aravind12a6's reply and I could able to get "AuditEvent_ForcedChange" audit class by doing 'Break Lock' on the object. But not able to modify the messages (not able to add different actions) for individual Audit classes.

Goto Library Structure->System Messages->Default Alarm System Config and filter for "Class", you shall get to see for each audit class what events you get

Thanks. Can't we able to modify the messages (add/delete different actions) for individual audit classes on that?
