FactoryTalk VS ME Application - Audit

[bicc]

Hi all,

Trying to debug some audit trail code for a customer.
Basically i am trying to understand how the audit trail is set up.
It is a panel view plus HMI and i am using FactoryTalkView Studio ME.
The vendor who developed the application is clearing the audit log using this a expression;
(AlarmStatusCode == 200) AND ({Conn)HMI.Touch.AuditMemoryErrorWarning} OR {(Conn)HMI.Touch.AuditMemoryErrorCritical})AuditStatus

I am unable to see where the vendor is setting the AlarmStatusCode to 200 in the HMI. Its not being set in the PLC.
Has anyone any knowledge of the above ?

Thanks
