Procedure using STEP 7
A description of how to save service data is available under the keyword "Save service data"
in STEP 7 online help.
Procedure using 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.
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.
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 card
slot of the CPU. Pay attention to the procedure described in Removing/inserting the
SIMATIC memory card on the CPU (Page 209).
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 transfer was successful, the STOP LED lights up. If
transfer was not successful, the STOP LED and the ERROR LED flash. In case of an error,
the CPU stores a text file with a note on the error that occurred in the DUMP.S7S folder.
