<div class="markdown_content"><p>Hi guys,</p> <p>I just started to use python script in codesys! My question is: is it possible to run a script in codesys and it executes the code as long as plc is running? <br/> For example, reading an string of integer value real-time.<br/> Thanks for your help in advance!</p></div>

<div class="markdown_content"><p>Hi guys,<br/> I followed all the instructions in this thread about executing external python scripts from Codesys. I was successful in running a blink LED script. However, I am unable to run a script containing just a simple <em>print('Hello World')</em>. Any ideas?</p></div>

<div class="markdown_content"><p>Hi guys, I've followed all your instructions but I can't visualize anything on my Adafruit dipsplay (ILI9341 driver).<br/> My python script is copied correctly from <strong>/var/opt/codesys/PlcLogic/Applicarion</strong> to <strong>/var/opt/codesys</strong> so I don't know what I'm doing wrong. Advices?</p> <p>P.S. obviously if I load my program from Python idle in my RPi, it works properly.</p> <p>EDIT: resolved. I tried to change "python" to "python3" in the code and it works!</p></div>

<div class="markdown_content"><p>Hi all,</p> <p>I would like to use this feature in Codesys (script lang) to transfer variable values between the PLC and a python script.</p> <p>First, I am trying to execute a simple python script using codesys with a RPI 3 B+ as PLC. I followed the example posted for the unicorn hat as reference. However, I do not have the hardware to test it so I developed a simple code "print()" to verify the code is running. <br/> Below the steps I have followed:<br/> 1. Add my script as external file in my CODESYS program. </p> <ol> <li> <p>Manually copy to the RPI my python script to the directory /var/opt/codesys/. I have also included <br/> <strong><span><span>[SysProcess]</span></span>Command=AllowAll </strong><br/> in both files <br/> <strong>/etc/CODESYSControl.cfg:/etc/CODESYSControl_User.cfg:</strong></p> </li> <li> <p>Download the Codesys Program to the RPI and run the program from CODESYS.</p> </li> </ol> <p>Although I do not receive any error nor compilation or execution, I can not observe my code running. Is there any step I am missing or I should skip?</p> <p>Thanks in advance</p> <p><img alt="IMG: interpreter_py.PNG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=3890"/></p></div>

<div class="markdown_content"><p>Hello,<br/> I tried to use your examples to run my python script. But there is no /var/opt/codesys directory. I can find my PlcLogic/Application directory only directly in root directory. Where is a problem. Is it possible to set it somewhere in development system?</p></div>
