Hey,

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??

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?

Thanks for your answers :)

The 30 minutes are counted from the start of the runtime with the application using EtherCAT master, so just reboot ;-)
Source: I did a trial back in 2019 for a licensed device which did not have EtherCAT license.

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.

Do I have possibilities to change or adjust settings in the configuration file for the Ethernet communication?

Hi, did you solve this thing with license? I have similar issue with modbus tcp slave... I installed license for library but same again.

Hi, unfortunately not.
But I think the problem was my Ethernet driver because I was running the runtime on a custom hardware with custom Linux Kernel.
