11.2 Reading out/saving service data
Procedure via the SIMATIC memory card
If it is no longer possible for technical reasons to communicate with the CPU via Ethernet,
you can also read out the service data via the SIMATIC memory card. To do this, proceed as
follows:
1. Insert the SIMATIC memory card into the card reader of your PC / programming device.
2. Open the job file S7_JOB.S7S in an editor.
3. Overwrite the entry PROGRAM with the string DUMP in the editor.
(Do not use any spaces/line breaks/quotation marks to ensure that the file size is exactly
4 bytes)
4. Save the file under the existing file name.
5. Make sure that the SIMATIC Memory Card is not write protected and insert it in the slot
on the CPU.
(for the CPU 1518-4 PN/DP, you need a card ≥ 2 GB and for the CPU 1511-1 PN,
CPU 1513-1 PN, CPU 1515-2 PN, and CPU 1516-3 PN/DP a card ≥ 32 MB)
Result: The CPU writes the service data file DUMP.S7S to the SIMATIC memory card and
remains in STOP mode.
The transfer of the service data has been completed as soon as the STOP LED stops
flashing and lights up continuously. If the transfer was successful, only the STOP LED lights
up. If the transfer was not successful, the STOP LED lights up and the ERROR LED flashes.
In case of an error, the CPU stores a text file with a note on the error that occurred in the
DUMP.S7S folder.
Use the SIMATIC memory card to read out the service data only if you are no longer able to
communicate with the CPU via Ethernet. In all other cases it is preferable to read out the
service data via the Web server or STEP 7.
