    Areas

    For plant organization:

    1. Alarms → Areas
    2. Create hierarchy:
    Plant/
  ??? Production/
  ?   ??? Line1/
  ?   ??? Line2/
  ??? Utilities/
      ??? Boilers/
      ??? Compressors/
    1. Assign alarms to areas

    Step 7: Test Alarms

    1. Start Runtime
    2. Open Alarms → Online
    3. Force tag values to trigger alarms
    4. Verify:
      • Alarm appears in list
      • Color coding correct
      • Sound plays
      • Email sent
    Step 8: Alarm

      • Summary Display

        Create operator display:

        1. Displays → New

        3. Configure:
          • Show: Active alarms
          • Columns: Time, Area, Message, Value
          • Filter: By area or priority
          • Allow: Acknowledge, silence

    For compliance:

    • Electronic signatures on acknowledgments
    • Audit trail cannot be disabled
    • User authentication required
    • Time synchronization enabled
    • Data integrity checksums

    Best Practices

    • Use consistent naming conventions
    • Set appropriate priorities (1-5)
    • Include clear messages
    • Test all alarm conditions
    • Document alarm philosophy
    • Regular alarm rationalization
