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 / Opera-

tor 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.

Parameter name and Value to which it 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 RCM unit through BACnet. RCM 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 till the value to which it is changed.

The string length of each instance of conguration change will be 50 Bytes in data

memory area of the controller.
