Playing an Audio or Video message

You can have the real-time screen play an audio message when an I/O point meets certain con-

ditions. The audio message must be a Windows Wave (WAV) file, which can be created with

a sound card, microphone and the Windows Sound Recorder program located under Programs>

Accessories>Multimedia. The Wave file can be set to play when an I/O value is Equal (EQ), Not

Equal (NE), Less Than (LT), Less Than or Equal (LE), Greater Than (GT), or Greater Than

or Equal (GE). To use this feature, follow the steps below. Note that the components placed

on the palette for this feature will be invisible in Run mode.

file you want played. You can click the Play box to hear the message play once.
