Hello:

Enable commands at /etc/CODESYScontrol.... (do not remember right name), add to settings:

[SysProcess]
Command=AllowAll

OR more safety:

[SysProcess]
Command.0=aplay
Command.1=mplayer
...

In Codesys program add variable:

VAR
   cmdResult   :    RTS_IEC_result;               // Command Result
END_VAR

And use command for play the sound (for aplay command):

SysProcess***ExecuteCommand('aplay /theway/tomusic/sound.wav', ADR(cmdResult));    // Delete that "***", I have to add it because forum filtering it

Remember, that program will stop at command until the sound is played. Its better to make 2nd Task for sound playing with using some buffer or mark at GLOBAL VARIABLE.

IF soundState THEN SysProcess***ExecuteCommand('aplay /theway/tomusic/sound.wav', ADR(cmdResult)); soundState:= FALSE; END_IF     // Delete that "***", I have to add it because forum filtering it

Maybe you have to add library:
SysTypes Interfaces
SysProcess

Thank you! This worked fine.

Hello,

I am currently testing a video file with:

Video_1: STRING: = 'sudo omxplayer -o both /home/pi/media/test.mp4';

The file is also played via the "omxplayer".
Works perfect,
But how can I finish playing that prematurely?

In the terminal I press "q"

is that possible?

Thank you very much
mfg mike

Edit: I got it working. Now that I have an account I can see the screenshot mentioned above. Just an addition, I had to click on the "display advanced libraries" in the Add Library window.

I am interested in getting this code to work on my Raspberry Pi 3 using CODESYS V3.5 SP10 P2 +. I have SysTypes Interfaces (3.5.2.0) and SysProcess (3.5.7.0) installed. I'm very new to CODESYS and Raspberry Pi.

In declaring the variable cmdResult, there is an error "Identifier 'RTS_EIC_result' not defined". I also tried

cmdResult   : POINTER TO RTS_IEC_result;

but I get the same error.

Also, regarding the SysProcessExecuteCommand (minus the ) I have the same "Identifier not defined" error. Is there an "Import" that I'm missing?

Hello:

I also have the same error RTS_IEC_RESULT Module not found, does anyone knows how to solve this problem.

Thank you best regards

is there someone who can explain me how to play an audio file in Codesys through LD.
I have added a file (.WAV) with Filezilla, or it is also possible to add a audio file in Codesys by right-clicking on application and add file.
