5.16 Slot for storage media
At the front of the CPU there is a slot for storage media. V
ia this slot
as external storage medium for applications and firmware you may
use a memory card (MMC respectively SD). You can cause the CPU
to load a project automatically respectively to execute a command file
by means of pre-defined file names.
Please note that the write protection function of SD
cards is not evaluated!
To the following times an access takes place on a storage medium:
n After overall reset
–
The CPU checks if there is a project S7PROG.WLD. If exists
the project is automatically loaded.
– The CPU checks if there is a project PROTECT.WLD with pro-
tected blocks. If exists the project is automatically loaded.
These blocks are stored in the CPU until the CPU is reset to
factory setting or an empty PROTECT.WLD is loaded
– The CPU checks if a MCC memory extension card is put. If
exists the memory extension is enabled, otherwise a memory
expansion, which was activated before, is de-activated.
n After PowerON
– The CPU checks if there is a project AUTOLOAD.WLD. If
exists an overall reset is established and the project is auto-
matically loaded.
– The CPU checks if there is a command file with
VIPA_CMD.MMC. If exists the command file is loaded and the
containing instructions are executed.
– After PowerON and CPU STOP the CPU checks if there is a
*.pkg file (firmware file). If exists this is indicated by blinking of
the LEDs and the firmware may be installed by an update
request.
n Once in STOP
– If a storage medium is put, which contains a command file
VIPA_CMD.MMC, the command file is loaded and the con-
taining instructions are executed.
