The first aspect of the violations with which OpenSCADA works from the start and which is most demanded is the notification in various ways. Since the notification is part of the user interface, it is implemented in the visualization engine UI.VCAEngine and the visualizers UI.Vision, UI.WebVision. Currently, the notification mechanism about the violates implements following functions, that have not yet been partially implemented in UI.WebVision:

  • Notification:
    • Visual — blinking in an alarm color for the object, the signaling group and the general status.
    • Beep — issuing a continuous signal, usually on the system "buzzer", and regardless of the violation.
    • Sound — playing a sound file or the speech synthesis from a text, associated with the violation.
    • By expanded special ways and through special notification mechanisms.
  • Quietance of the violation notification:
    • Fully — by clicking on the colored flashing circle status of violations (the event "ws_alarmLev"), to the right bottom.
    • By the notification way — separately visual (the event "ws_alarmNtf0"), beep (the event "ws_alarmNtf1"), audio (the event "ws_alarmNtf2") and expanded (the event "ws_alarmNtf{N}"); by pressing the button with the corresponding image to the right of the bottom or under the view types buttons.
    • By the violation object — the visual presentation shape can be appended for the quietance command of the notification, directly by itself;
    • In turn, with listening — is characterized for the sound notifications, because each object of the violation can provide its own sound message or synthesis of speech.
