You may use the MCC also as "normal" MMC for storing your project.
n
If the memory expansion on the MCC exceeds the maximum extendible memory
range of the CPU, the maximum possible memory of the CPU is automatically used.
n
You may determine the recent memory extension and the remaining time after pulling
the MCC via the integrated web page.
Chap. 5.11 ‘Accessing the web server’
n
When the MCC memory configuration has been taken over you may find the diagnos-
tics entry 0xE400 in the diagnostics buffer of the CPU.
n
After pulling the MCC the entry 0xE401 appears in the diagnostics buffer, the SF-LED
is on and after 72 hours the CPU switches to STOP. A reboot is only possible after
plugging-in the MCC again or after an overall reset.
n
After re-plugging the MCC, the SF LED extinguishes and 0xE400 is entered into the
diagnostics buffer. You may reset the memory configuration of your CPU to the initial
status at any time by executing an overall reset without MCC.
CAUTION!
Please regard that the MCC must remain plugged when you’ve executed
the memory expansion at the CPU. Otherwise the CPU switches to
STOP after 72 hours. The MCC cannot be exchanged with a MCC of the
same memory configuration. The activation code is fixed to the MCC by
means of an unique serial number. Here the functionality as an external
memory card is not affected.
To the following times an access takes place on a storage medium:
After overall reset
n
The CPU checks if a MCC is plugged. If so, the according additional memory is
unlocked.
n
The CPU checks whether a project S7PROG.WLD exists. If so, it is automatically
loaded.
After PowerON
n
The CPU checks whether a project AUTOLOAD.WLD exists. If so, an overall reset is
executed and the project is automatically loaded.
n
The CPU checks whether a command file with the name VIPA_CMD.MMC exists. If
so the command file is loaded and the commands are executed.
n
After PowerON and CPU STOP the CPU checks if there is a *.pkg file (firmware file).
If so, this is shown by the CPU by blinking LEDs and the firmware may be installed by
an update request.
Chap. 5.14 ‘Firmware update’ page 65
Once in STOP state
n
If a memory card is plugged, which contains a command file VIPA_CMD.MMC, the
command file is loaded and the containing instructions are executed.
The FC/SFC 208 ... FC/SFC 215 and FC/SFC 195 allow you to include
the memory card access into your user application. More can be found in
the manual operation list (HB00_OPL_SP7) of your CPU.
