*Connected via spur lines for commisioning/maintenance only
(with default MPI address).
** connected to the MPI subnet later (with default MPI address).
*** the CP also has a PROFIBUS address in addition to the MPI address ( address 7 here).
**** In the case of the CPU 318-2 DP, the FMs/CPs do not have their own MPI address. In the case
of the S7 300 CPUs, (without CPU 318-2 DP) you can also allocate MPI addresses as you wish.
