If you want to avoid using Advanced function blocks, you can use the SILO function block to save a Boolean variable to a text file and write your own external script for watching this file and playing the sound when the contents of the file change.
Both approaches can be used, it all depends on how much you value your time.

]]>I have prepared an example on playing sounds on the Raspberry Pi for you. There is a readme file attached. Using an external audio player is of course not the best way to go...
For this application you need the Advanced function blocks which are not included in the demo verison. This is the package you might be interested in: https://www.rexcontrols.com/product/rex … spberry-pi
