CPU memory reset
Performing a general reset of the C7-CPU 613 (clearing the memory
and reloading the user program from Flash memory) requires a
special operating mode key procedure:
1. Select STOP mode by pressing the DOWN key.
– The “S” key LED lights up
– The CPU status LED “STOP” is lit.
2. Select MRES mode by pressing the UP key and the DOWN key
at the same time. The “M” key LED lights up.
3. Hold the keys down until the “STOP” status LED lights up a
second time and until remains lit (this happens after 3 seconds).
4. Now release the keys.
5. Within three seconds, press both keys once again
simultaneously.
6. Release the keys when the “STOP” status LED flashes rapidly
(at 2 Hz).
When the CPU has finished the clear/reset operation, the “STOP”
status LED stops flashing and remains lit. The CPU is now reset
and in STOP mode.
You need to perform the steps described in the table above only if you want to
reset the memory of your C7-613, and without the C7-613 having requested a
memory reset (indicated by slow flashing of the “STOP” status LED). If the general
reset request comes from the C7-613, the process can be started by briefly
pressing both keys.
In specific situations you may need to reformat your MMC if the C7-613 requests a
second memory reset. For information, refer to the
S7 300 Automation System
CPU Data: CPU 31xC and CPU 31x
manual, chapter “Installation and
communication functions”, SIMATIC Micro Memory Card (MMC), “Formatting the
MMC after memory reset.”
When the group error LED SF of the C7-613 is lit, you need to analyse the data in
the diagnostic buffer of the C7-613 on your PG/PC. More information about the
entries in the diagnostic buffer is provided in the STEP 7 Online Help.
