Setra Systems SRCM - Event Log

34
Event Log
The SRCM can be enabled with an audit trail of changes made to the congurations/
modes of the system by Supervisor and Operator. When the Supervisor / Operator
changes any conguration through the menu, the action is captured and stored in a
string covering the User prole Screen name where the parameter is changed. There
will be 5 such instances stored in non-volatile memory of the unit. Any power failure
in the unit will lose the data and it will be the responsibility of BMS system to log
these strings after polling from the SRCM unit through BACnet. The SRCM unit
will store these strings as different instances of Character String Object.
The value to which the parameter is changed will not be logged for parameters like
User Dened Condition Banner text, Room Label, Message Text, etc., which needs
more memory. Other parameters whose variables are enumerated, real and integer
will be logged until the value is changed.
The string length of each instance of conguration change will be 50 Bytes in the
data memory area of the controller.
