<div class="markdown_content"><p>Hello, </p> <p>I am currently having issues on CODESYS Control for linux SL with DTH expiring. I have followed several tutorials of creating a proper RT linux. Then I further configured the linux based on this tutorial: <a href="https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_performance_optimization.html" rel="nofollow">https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_performance_optimization.html</a></p> <p>Currently I am getting DHT expires in the communication and I am trying to increase of the priority of the network task which manages the PROFINET network adapter. </p> <p>I am following this tutorial: <a href="https://content.helpme-codesys.com/en/CODESYS%20PROFINET/_pnio_trouble_connection_failure.html" rel="nofollow">https://content.helpme-codesys.com/en/CODESYS%20PROFINET/_pnio_trouble_connection_failure.html</a></p> <p>But the irq-set is not changing the priority. See the image bellow.... <br/> <img alt="irq-prio.png" src="../irq-prio.png"/></p></div>
