There is an address from plc program which is triggered by certain condition i.e. high or low value.

Are you using the SoundPlayer component or writing code?

Try using the attached modified version of the SoundPlayer.

Remove the current SoundPlayer component from the form, save and close the form, replace the stock version in the AdvancedHMIControls/Components folder with the modified one, rebuild the solution.

The modified version only has 2 triggers, PositiveChange and NegativeChange (AnyChange was removed) and a new LoopSound property.
The change of value will start/stop sound playback when the LoopSound property is set to True, otherwise it will play sound only once.

i found the easiest solution:

1. in the solution explorer, go to Controls>Components>SoundPlayer.vb
2. right click SoundPlayer.vb>view code
3. expand the Events and see the Private Sub PlaySound()
4. Change the player.Play() to player.PlayLooping()
5. Rebuild and Save the project.

How do you stop the sound playback?

that will be from the PLC program.
so at the moment i have a BarLevel indicator with high and low setting.
if above high and below low limit, the sound alarm will activate (program in the PLC).

did i miss out anything? please let me know.
