Dear all,

I´d like to establish a communication between an S7-400H and a standard CPU (like f.i. S7-300).

I´ve checked in the attached documentation;

- S7_400H_Red.pdf (chapter 9.5)

- s7300_s7400.pdf (chapter 29)

But i still need some info about how to program the blocks, and where.

I know (or at least i think) that i´ve got to create S7 connections in NetPro cause we´re not allowed to create S7-fault tolerant connection... But what else do we need to configure in terms of blocks to make this work?

Thanks a lot in advance for your support.

Best Regards - Mit freundlichem Gruß
