Sick QR Scanner

Hey guys i have a question: 
Im trying to use the Sick Lector 611 and IRC5 with Profinet. I am able to create a communication between the 2, so that for example i can read the CTRL bit ready and trigger the scanner via ctrl bits. But im not able to read the return of the scanner. im using the 32byte input for that, but i dont get any response even if i try to read every bit of the 255.

this is what my robotstudio config looks like. 

is there any documentation that could help me?

I hope this is not a stupid question, since i am a beginner with the io engineering tool and profinet.
