EtherCAT Master Beckhoff slave not found

Hello, dear forum,My name is Christoph, and I’m thinking about building a small CNC milling machine. I already have a CNC lathe with an Acorn from Centroid that works. Now I’d like to try out LinuxCNC. LinuxCNC is completely new territory for me, and I’m counting on your support. I’d like to implement the control system using EtherCAT. I have a Beckhoff EK1101 and a few input and output terminals. I’ve set up a virtual environment on my computer and followed all the steps in the YouTube video by talla83. Unfortunately, no slaves are being detected. Now I’m not sure how to proceed. Can you help me? Thank you very much in advance for your help. 

Wenn du dir die Videos von Talla angesehen hast, denke ich du kommst aus den deutschen Raum.

Zunächst, der Screenshot sagt nicht viel aus.
Schreib mal zusammen, welche Schritte du bisher unternommen hast.
Blinken eigentlich die grünen LED am Netzwerkkabel wenn du es angesteckt hast?
