Hello Mike and Andreas,

at this location I could only find the ethercatctl-file.
However I think I found the right file now in 
/usr/src/etherlanmaster-code/tools. The file is named "ethercat" and I 
also found several .o-files with etherlab commands like "master". 
Executing it with sudo ./ethercat master worked and the output was 
(after starting with "systemctl start ethercat"):

and for "slaves":

0:0  PREOP  +  EK1100 EtherCAT-Koppler (2A E-Bus)
1  0:1  PREOP  +  EL1104 4K. Dig. Eingang 24V, 3ms, Sensorversorgung
2  0:2  PREOP  +  EL2004 4K. Dig. Ausgang 24V, 0.5A
3  0:3  PREOP  +  EL3062 2K.Ana. Eingang 0-10V


I tried my Simulink Model again but it still doesnt work.
I will attach a Screenshot of it.

I attached a cable from Input 2 of EL1104 (which is +24 V) to Output 1 
of EL2004. The LED of EL2004 Output should now be on since it recieves 
24V.

I used Slave Index 1 for the EL1104 and Index 2 for the EL2004 as it was 
shown in the Terminal.

Master is 0 and Vector Outputs enabled.

Also the Master State-Module doesnt show any outputs.



Regards
Henrik
