A pre-recorded message is required using .wav, .mid, .mp3, or other media format. You can record the message yourself or copy them from the Internet. A sound card and speaker is required on the SCADA node and Clients. Software to play the media file is also required on the SCADA Node and Clients (e.g. windows media, real player, etc.).
The media files should be copied to drive:\WebAccess\config\Node\project_node on the Project Node. They will be downloaded to the SCADA nodes and from SCADA nodes to Clients by WebAccess network service.
You can specify a separate Media file for each alarm.
The Media File is played only once when the Alarm occurs. It does not repeat if the Alarm remains unacknowledged.
Hint - Use a Global Script to play a Wave or MIDI or other MCI file to repeat Alarm Annunciation if Alarms remain Unacknowledged. See 12.10.20 Play a Wave File if UNACK Alarm (Global Script).
Alarms must be enabled for the Tag. A Media File must be specified for the Analog Tag Alarm Properties or Discrete Tag Alarm Properties.
