Alarm screens

View Designer
 provides two default alarm screens. It also provides two alarm table graphic elements to create alarm screens for different size HMI devices:
  • Alarm Summary.
    The Alarm Summary is a list of alarms that are in
    interesting
    states or require attention, such as alarms that are In Alarm and Unacknowledged.
  • Alarm Manager.
    The Alarm Manager is a list of all alarms regardless of their state. Alarms listed in the Alarm Manager include all conditions for an alarm.
Alarms from controllers are continuously evaluated to determine whether they are:
  • In Alarm.
     Present conditions have caused the alarm to become active.
  • Normal.
    Present conditions have not caused the alarm to become active, so the alarm is inactive.
TIP:
Tips:
  • Operations on alarms may be limited. Alarm operation buttons may be disabled in
    View Designer
    . Disabled buttons have diagonal hash marks across them. When selecting a disabled button, an
    Error
    icon Icon: Runtime Error button appears on the button for 10 seconds. Selecting this icon opens an
    Error list
    with the message that the button is disabled. Disabled buttons do not perform the associated task.
  • If no language is defined in the controller, alarm tables show messages defined in the controller. If messages are not defined in the controller, the
    Message column
     in an alarm table appears blank without error.
  • If languages are defined in the controller and English-US is one of the defined languages, the message in the English-US language appears in the
    Message column
     of the alarm table. If no English-US string exists or if the English-US language is not one of the defined languages in the controller, the
    Message column
     appears blank without error.
  • For tag-based alarms, Alarm Manager and Alarm Summary display alarms marked as active and ready for evaluation. The 5380, 5480 and 5580 Logix families of controllers support tag-based alarms.
