Memory extension with MCC
With the SC CPU there is the possibility to extend the work memory of your
CPU.
For this, a MCC memory extension card is available from VIPA. The MCC
is a specially prepared MMC (
M
ulti
m
edia
C
ard). By plugging the MCC into
the MCC slot and then an overall reset the according memory expansion is
released. There may only one memory expansion be activated at the time.
On the MCC there is the file
memory.key
. This file may not be altered or
deleted. You may use the MCC also as "normal" MMC for storing your
project.
To extend the memory, plug the MCC into the card slot at the CPU labeled
with "MCC" and execute an overall reset.

Overall reset
MCC
memory is extended for the MCC memory
configuration (diagnostic entry 0xE400)
If the memory expansion on the MCC exceeds the maximum extendable
memory range of the CPU, the maximum possible memory of the CPU is
automatically used.
You may determine the recent memory extension via the Siemens
SIMATIC Manager at
Module Information
- "Memory".
Attention!
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 48h. The MCC can not be exchanged with a MCC of the same
memory configuration.
When the MCC memory configuration has been taken over you may find
the diagnosis entry 0xE400 in the diagnostic buffer of the CPU.
After pulling the MCC the entry 0xE401 appears in the diagnostic buffer,
the SF-LED is on and after 72h the CPU switches to STOP. A reboot is
only possible after plugging-in the MCC again or after an overall reset.
After re-plugging the MCC, the SF-LED extinguishes and 0xE400 is
entered into the diagnostic buffer.
You may reset the memory configuration of your CPU to the initial status at
any time by executing an overall reset without MCC.
