MPI Addressing
You Have a CPU as of Order Number and
Version:
Your CPU version and order number is lower
than the following:
6ES7312-5AC01-0AB0, version 01
6ES7313-1AD02-0AB0, version 01
6ES7314-1AE03-0AB0, version 01
6ES7314-5AE02-0AB0, version 01
6ES7315-1AF02-0AB0, version 01
6ES7315-2AF02-0AB0, version 01
6ES7316-1AG00-0AB0, version 01 –
and STEP 7 V4.02 or later and STEP 7 < V4.02
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.
The CPU automatically establishes 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
6ES7314-1AE03-0AB0, version 01
