Wincc direct to pac3200 profi net

Hi all,

We are running wincc prof v14 and would like to read from pac3200 energy meters directly i.e no plc in between. We have the profinet connection set between the 2 in the project, pac3200 set as io device and the io device controller set as pc's IE controller IE_general_1.

How do we access the reads and display them like you would a normal tag? for instance real power is the pac3200's input word 20-24 how do i "link" that to a screen object? I dont seem to be able to reference the address in either a direct tag setting, tag table or connections? 

I am guessing its something really simple but i cant figure it out!

Thanks,

Harry
