Hello everybody

I am quite new on this, I am working on a project which include a sentron pac 4200 and a PLC S7-1200. So what i know is that in order to have info from sentron pac i need to use a FB which is MB_CLIENT. My concern is, how can i obtain the info from this block?

Physically i connected the sentron pac to the PLC through profinet.

In my main OB1 i have the FB MB_CLIENT and the correspondent data block. 

Now i need the info. 

Somebody have an idea how can i make it?

Thanks in advance.
