Disable Alarms
If an alarm does not appear to be operating as designed, or is determined to be unnecessary, an operator can disable it. A disabled alarms is ignored by the alarm system until it is returned to an enabled state (see Enable a Disabled Alarm).
Note: If the parameter [Alarm]DisplayDisable is set to 1, the system will continue to process state changes for alarms that are disabled. This means any state changes can continue to be displayed at runtime, for example, on the SOE and Disabled Alarms page. They will not display on the Active Alarms page.
If your project uses the StruxureWare or Tab Style templates (accessible via a starter project), you can disable alarms during runtime from the Active Alarms page.
In a standard project, you need to define a command that uses the AlarmDisable() function to disable alarms.
Note: You can also "shelve" an alarm, which will temporarily disable it for a specified period of time. In a Situational Awareness project, only shelving is supported. You are not able to permanently disable an alarm. See Shelve Alarms.
