 Hello Manish,

have you already seen this:

Backplane bus in S7-300 and S7-400 - Entries ... - Siemens

backplane communication - Entries - Siemens Industry ...

S7-300 uses different than S7-400 (rack forms a backplane bus)

more details are there:

https://support.industry.siemens.com/tf/ww/en/posts/backplane-bus-in-s7-300-and-s7-400/51865/?page=0&pageSize=10

in short terms backplane bus is used for communication between CPU and modules

fitted to its rack (di, dq, ai, aq, comms modules, etc.)

hi MANISH,

there is one thing i didn´t read in the other Threads.

There are two types of K-Bus:

-the K-Bus is performed as "partyline", that means it is physically wired to the MPI-Interface. This structure you will find in CPU312 - 315-2DP

-the K-Bus is not performed as "partyline", that means K-Bus and MPI-Interface are disconnected. This structure you will find in CPU315-2PN/DP - 319-3PN/DP.

hope this helps,

regards,

Thank you all experts !
