I have to communicate a S7-400 ( with CP 443-1 ) and a WinCC Station into a Industrial Ethernet ISO protocol. What is necessary to do into the PLC program? Is there FBs for that? Please, I aprecciate any hint about it because it is my first time in Siemens PLCs.

You can use the S7 protocol on the Industrial Ethernet. That way you would not have to *anything*. Just define tags from differnt memory area (ie I, Q, M, DB etc).

Otherwise, you can use the SEND/RECEIVE blocks. The detailed information about this could be found from the NCM manuals (IE).
Hope this helps.
