15.2 Reading out/saving service data
Procedure using the SIMATIC memory card
Use the SIMATIC memory card to save the service data if communication with the CPU is not
possible over the Ethernet. In all other cases, save the service data using STEP 7.
The procedure using the SIMATIC memory card is more time-consuming than the other
options for saving the service data. You must also ensure before saving that there is sufficient
memory space on the SIMATIC memory card.
Proceed as follows for the R/H-CPU to save service data using the SIMATIC memory card:
1. Insert the SIMATIC memory card into the card reader of your PC/PG.
2. Open the job file S7_JOB.S7S in an editor.
3. Overwrite the entry PROGRAM with the STRING or character 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. Make sure that the SIMATIC memory card is not write-protected. Insert the SIMATIC memory
card into the card slot of the CPU.
For the R/H-CPU, you require one card ≥ 32 MB in each case.
5. Save the file under the existing file name.
Result: The CPU writes the service data file DUMP S7S to the SIMATIC memory card and
remains in STOP.
Service data transfer is complete when the STOP LED stops flashing and is lit continuously. If
service data transfer has been successful, only the STOP LED lights up.
In the event of errors in transfer, the STOP LED is lit continuously and the ERROR LED flashes.
The CPU also stores a text file with information on the error that occurred in the DUMP.S7S
folder.
