New Alarm Function
The New Alarm function will add a new alarm to the Historian archive. It will take the inputs shown in the following table.
| Input | Description |
|---|---|
| Source | Specifies the source for the alarm. |
| Condition | Specifies the alarm's condition. |
| Tag Name | Specifies the tag name for the alarm. Note: If you want the new alarm to be associated with the tag passed in, ensure you have first added the tag to Historian. |
| Timestamp | Specifies a timestamp for the alarm. |
| SubCondition | Specifies a sub-condition for the alarm. |
| Event Category | Specifies an event category for the alarm. |
| Message | Specifies a message for the alarm. |
| Severity | Specifies a severity for the alarm. |
Note: If the archive already contains an Open alarm for this tag/condition, its quality will be set to BAD before the new alarm is added. To avoid this, return the existing alarm to normal through the Return to Normal method before adding a new alarm.
