Odd Notification Pipeline Behavior

I have set up a simple alarm on a tag to send an email notification when the tag value is zero. I have an active delay of 5 seconds.

  • The notification test email through the Gateway works properly.
  • The alarm triggers properly when the tag is set to 0.
  • The pipeline is selected for the active pipeline in the alarm settings.

Despite this, the alarm rolling to "Active" will not send the email. I believe it is not triggering the pipeline at all as I have added a logger script in the pipeline and do not see any of the logs in the logger.

How are you testing? Are you directly writing a value to the tag, or are you opening the tag editor to supply a new value?

So it turns out that the "Notify Initial Events" selection in the Gateway settings under Alarming -> General fixed this issue.
