MPI Addressing
You Have a CPU as of Order Number and
Version:
6ES7316-1AG00-0AB0, version 01
and STEP 7 V4.02 or later
The CPU accepts the MPI addresses configured by
you in STEP 7 for the relevant CP/FM in an S7300
or
automatically determines the MPI address of the
CP/FM in an S7-300 on the pattern
MPI addr. CPU; MPI addr.+1 MPI addr.+2 etc.

MPI with 19.2 Kbps
With STEP 7 as of V4.02 you can set a transmission rate for the MPI of 19.2 Kbps.
The CPUs support 19.2 Kbps as of the following order numbers:
6ES7312-5AC01-0AB0, version 01
6ES7313-1AD02-0AB0, version 01
