I think it is not allowed to combine commands / echo + netcat</p>
<p>stop the service by:<br/>
sudo /etc/init.d/codesyscontrol stop</p>
<p>start it manually by<br/>
cd /var/opt/codesys<br/>
sudo /opt/codesys/bin/codesyscontrol_armv6l_raspberry.bin -d /etc/CODESYSControl.cfg</p>
<p>Once again I would recommend to do this UDP sending stuff by netbase services library like in the link in the upper post.</p>

Can You test again program netcat to for example send some UDP packet, it will be for shure that it was executed properly or not.<br/>
When I try command ```</p>
<p>"echo message <code>date +%s</code> | nc -u -w 0 192.168.1.1 2000"</p>
<p>``` UDP packet is not sended, probably netcat with this parameter is not executed.<br/>
Can You explain how to run this debug mode from previous post?</p>
<p>In CODESYSControl_User.cfg I have:<br/>
<span>[SysProcess]</span><br/>
Command=AllowAll</p></div>SysProcess.SysProcess.Execute.Command how to start linux program2020-02-27T16:01:43.032000Z2020-02-27T16:01:43.032000Zeschwellingerhttps://forge.codesys.com/u/eschwellinger/https://forge.codesys.comced2180203496f4d2b317c96212c157c802d260c<div class="markdown_content"><p>Hi,<br/>
not sure what exactly you want to archive but I would recommend to send or receive UDP frames<br/>
that way:<br/>

<p>How do you get this debug info?</p>
<p>Can You try command ><strong>Zitat:</strong><br/>
"echo message <code>date +%s</code> | nc -u -w 0 192.168.1.1 2000"</p>
<p>This should send UDP message "message <code>date +%s</code>" to 192.168.1.1 on port 2000. <br/>
In Your test program netcat was executed, but I cant send UDP message.<br/>
If somethisg is not clear feel free to ask.</p></div>SysProcess.SysProcess.Execute.Command how to start linux program2020-02-27T16:01:40.063000Z2020-02-27T16:01:40.063000Zeschwellingerhttps://forge.codesys.com/u/eschwellinger/https://forge.codesys.comf0013315286893e29fb55df43c6d0eac72a8f891<div class="markdown_content"><p>Hi,<br/>
hm.. looks like a bug,<br/>
I see if I add the command to /etc/CODESYSControl_User.cfg:</p>
<p><span>[SysProcess]</span><br/>
Command.0=shutdown<br/>
Command.1=netcat</p>
<p>and start the runtime manually ( to have more debug info), we see that netcat is executed, anyway somehow the result is not delivered to the SysProcessCommand2 in the IEC code.<br/>
Seems a to be a bug. <br/>
Please add a bugreport with your application attached to the store -> my question -> bugreport</p>

Simple command like ```</p>

then nothing happen. Even when I create script with netcat command and I will run this script from codesys its not working. When I run this script from shell its working properly.<br/>
This is some codesys limitation or I am doing something wrong?<br/>
Somebody try to start any linux program from codesys?</p></div>
