A maximum of 32 PG/OP connections is supported by MPI. The transfer
via MPI takes place with the following proceeding:
• Connect your PC to the MPI jack of your CPU via a MPI programming
cable.
• Load your project in the SIMATIC Manager from Siemens.
• Choose in the menu Options > Set PG/PC interface.
• Select in the according list the "PC Adapter (MPI)"; if appropriate you
have to add it first, then click on [Properties].
• Set in the register MPI the transfer parameters of your MPI net and type
a valid address.
• Switch to the register Local connection.
• Set the COM port of the PCs and the transfer rate 38400Baud for the
MPI programming cable from VIPA.
• Via PLC > Load to module you may transfer your project via MPI to the
CPU and save it on a MMC via PLC > Copy RAM to ROM if one is
plugged.
As external storage medium a MMC is deployed.
The MMC (Memory Card) serves as external transfer medium for programs
and firmware for, among others, it provides the PC compatible FAT16 file
system. With an overall reset or PowerON the MMC is automatically read.
There may be stored several projects and sub-directories on a MMC
storage module. Please take care that your current project engineering is
stored in the root directory. For reading from the MMC the following file
names must be used:
• Read after overall reset:
S7PROG.WLD (S7 project file)
PROTECT.WLD (Extended Know-how protection)
• Read after PowerON:
AUTOLOAD.WLD (S7 project file)
When the MMC has been installed, the write command stores the content
of the battery buffered RAM as S7PROG.WLD at the MMC. The write
command is controlled by means of the Siemens hardware configurator via
PLC > Copy RAM to ROM. During the write process the "MCC"-LED of the
CPU is blinking. When the LED expires the write process is finished.
