<div class="markdown_content"><p>Hi, unfortunately not. <br/> But I think the problem was my Ethernet driver because I was running the runtime on a custom hardware with custom Linux Kernel.</p></div>

<div class="markdown_content"><p>Hi, did you solve this thing with license? I have similar issue with modbus tcp slave... I installed license for library but same again.</p></div>

<div class="markdown_content"><p>Understood. Then I can be sure that the error is not in the license but somewhere in the operating system or the internal LAN settings.</p> <p>Do I have possibilities to change or adjust settings in the configuration file for the Ethernet communication?</p></div>

<div class="markdown_content"><p>The 30 minutes are counted from the start of the runtime with the application using EtherCAT master, so just reboot ;-)<br/> Source: I did a trial back in 2019 for a licensed device which did not have EtherCAT license.</p></div>

<div class="markdown_content"><p>Hey,</p> <p>I am using the CODESYS Control for Linux ARM SL Demo Version but I am not able to connect my Beckhoff EtherCAT-Slave to my PLC. The status in the development system says that the EtherCAT-master is running in Demo-Mode and the slave isn´t running but there is even no data on the bus so the master isn´t running??</p> <p>Is it possible that I can use the EtherCAT-Master-Demo-Version only once for 30 minutes and then it´s over or do I only need to restart the Runtime and I have another 30 Minutes for testing?</p> <p>Thanks for your answers :)</p></div>
