Among these connections, one is always reserved for PG and another for OP. The MPI makes it possible to set up a simple network with a maximum of 16 CPUs via "global data communication". \par\plain\f1\fs18 \'b7\plain\f0\fs18\tab MPI/PROFIBUS\~DP interface;\line The MPI can be converted to PROFIBUS\~DP and then used as a master. However, the integrated communication functions can then no longer be used\par\plain\f1\fs18 \'b7\plain\f0\fs18\tab PROFIBUS DP interface;\line The CPU\~318-2\~DP with PROFIBUS\~DP master/slave interface supports the implementation of distributed automation configurations with high speed and ease of handling. From the user's point of view, the distributed I/O is treated as central I/O (same configuring, addressing and programming).\line Mixed configuration: SIMATIC S5 with SIMATIC S7 as PROFIBUS master according to EN\~50170 \par\plain\f1\fs18 \'b7\plain\f0\fs18\tab Key-operated mode selector;\line Access privileges to user data can be restricted with the removable mode selector keyswitch\par\plain\f1\fs18 \'b7\plain\f0\fs18\tab Memory card;\line for expansion of the integrated load memory. Beside the programs, the information contained in the load memory includes the parameterization data of the S7-300 with CPU\~318-2\~DP and therefore requires about twice as much memory. The result is: \par\pard\fi-284\li568\tx284\tx568 -\tab Integrated load memory is not adequate for large programs so that a memory card is often required.\line RAM and FEPROM cards (FEPROM for storage in de-energized state as well) are available.\line\line\plain\f0\fs18\b Note for FEPROM memory cards:\plain\f0\fs18\line The memory cards may be subject to \plain\f0\fs18\cf3 usage restrictions\plain\f0\fs18  depending on the CPU version. \line For CPUs with Order No.: 6ES7\~318-\plain\f0\fs18\b 2AJ00\plain\f0\fs18 -... and all more recent versions, memory cards with Order Nos.: 6ES7\~951-\plain\f0\fs18\b 0\plain\f0\fs18 ... and 6ES7\~951-\plain\f0\fs18\b 1\plain\f0\fs18 ... can be used.\line For older versions, \plain\f0\fs18\b only\plain\f0\fs18  memory cards with Order No.: 6ES7\~951-\plain\f0\fs18\b 0\plain\f0\fs18 ... can be used.\line\par\pard\fi-284\li284\sb60\tx284\plain\f1\fs18 \'b7\plain\f0\fs18\tab Real-time clock;\line the date and time can be appended to diagnostic messages of the CPU\par\pard\par }
