10.2 Reading out/saving service data
CPU 1516pro-2 PN (6ES7516-2PN00-0AB0)
112 Operating Instructions, 09/2016, A5E35873416-AA
A description of how to save service data is available under the keyword "Saving service
data" in the STEP 7 online help.
Procedure via the SIMATIC memory card
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.
Before reading out the service data, you must ensure that there is sufficient memory space
on the SIMATIC memory card.
To read service data using the SIMATIC memory card, follow these steps:
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.
To ensure that the file size is exactly 4 bytes, do not use any spaces/line
breaks/quotation marks.
4. Save the file under the existing file name.
5. Ensure that the SIMATIC memory card is not write protected and insert it in the card slot
of the CPU. Follow the procedure in section Inserting/replacing SIMATIC memory card
(Page 73).
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.
