I'm looking a way to connect MP to S7-400H via Profibus-DP.
On the official site http://support.automation.siemens.com/W ... n/22584322
it is stated that there are two ways:
with two RS-485 repeaters
(one of them has no power concerning with which CPU is master)

and software solution (ChangeConnection function with different MPI adress for CPU1 and CPU2)

Who knows other ways? Maybe with non-Siemens terminals?
Thanks!
