Operator logging is a feature in VTS that logs any value changes made to output tags and their related equipment via tag drawing methods such as SetValue Button, SetValue Hotbox, Numeric Entry field, and Slider. Data recorded includes the operator's username, the name and description of the tag, the new value, and the workstation from which the change was made. Detailed information on the new operator logging feature can be found in "VTS Developer's Guide: 8: Default VTS and VTScada Pages: Alarm Page: List Options Buttons: Operator Control Action Logging ".
The OperatorLogging variable enables you to turn operator control action logging to the Alarms.log file on or off. By default, operator control action logging is turned on (OperatorLogging = 1).
If set to 0 (false), then control actions performed by operators are not logged to Alarms.log, and consequently cannot be displayed in the History list on the Alarm page.
If set to 1 (true), then control actions performed by operators are logged to Alarms.log, and can be viewed in the History list on the Alarm page.
Default: OperatorLogging = 1
Enables you to set the area for logged operator control actions so that operator control action entries in the History list can be conveniently sorted.
Default: OperatorLogArea = OperatorLog
Enables you to set the name to be displayed for all logged operator control action events (for example, the setting of a digital output tag via a SetValue button to 1).
Default: OperatorLogName = OperatorLog
