Hello Hakan,
the Modbus wizard is only applicable for ModbusTCP communication via PN-CPUs.

When you like to run ModbusTCP via a CP you need a connection in NetPro and the according library.

Would it not be with CP443-1?

Or with WinCC v6.2, will you? 
Free Modbus TCP OPC Server you know? ( I can do this job with the demo program at the moment. 1 week time left)

So how do I do? 
I will read/write data on "Modbus TCP Gateway I/O" and "Energy Analyzer" 
Just want to send and receive only a few data

I connect both devices with Modbus address via TCP/IP on "Modbus Poll" (see the pictures)
I want to do with the PLC or the WinCC v6.2

Thank you very much for your help

Hello Hakan,
you can find information of the ModbusTCP library here.

I'm afraid, I'm not experienced with WinCC.
