Setup I/O Link

Hi

I got an I/O Link between two robots already hooked up but I need to somehow set up the connection. On both robots I can see that there is a Type A connection when I go to [I/O] and then to [I/O Link] (see attachment). There I can not make any settings.

I see that it is on Rack 1 and in Slot 0.

So I guessed by myself that I just needed to assign now the Digital Outputs to the right Rack and Slot and it should work, but unfortunately it is not. I got a list with all rack assignments (also see attachment). There I see The Model A I/O Link should be assigned to Rack 0 and not 1 like mine. But I can not find a menu or a manual in how to change this.

I also tried to just assign the DO to the Rack 1 and Slot 0. Also this without any success.

Can anyone give me a hint how i make the settings?

Thanks!

The robots are connected as slaves to the PLC with Profibus. But I do not have access to the PLC and so i guess I can not send data trough this communication method.
I recently connected all the robots with Ethernet to access them remotely. So the connection over Ethernet would be there, but the Ethernet//IP communication is not installed on the robots. So I can not use this either.

Do you use I/O Link to connect to the PLC or what is the normal useage of I/O Link? What exactly is Model A and Model B I/O?

I'm new to this field, sorry for so many basic questions.
