MP377 WITH CPU412-3H CONTROLLERS

Hello every1!

My configuration goes like thisan MP377 with CPU412-3H controllers.For connecting an MP377 directly to the H Controllers via software solution ,we need to connect both the H systems to MPI connection.But since CPU412-3H has only port with an option of configuring it either as MPI/DP,for connecting the I/O cards through IM153 redundancy bundle,i have configured it as a DP port.Now how is it possible to connect MP377 to H Controllers.

Pls help......
Im worried since my projectis nearing to its final stages.....

Im confused only reading that link.Tell which case is applicable for my system configuration.I guess its case 4 Connecting an operator panel to the controller via two repeaters ,If im not wrong.
Pls find attached the system configuration.
What confuses me is in all the examples shown,the CPU has one MPI/DP port and another DP port.But in my case only one port which can be either as MPI or DP port.

Is it possible yo use a Y-Link instead of repeaters?

Hello!Thanks for ur reply.I was confused,now got an idea.I have another H station of similar configuration.In my project I have take some of the I/Os of one station to another station and indicate it on MP377.How is it possible on Ethernet.I was told in another tread to have parallel paths between H station and share the DBs.Let me know how????????

Regards

S7 connection, fault-tolerant,and ISO transport connection.I think s7 connections is more suitable for our project
