12.2 Reading out/saving service data
S7-1500R/H redundant system

System Manual, 10/2018, A5E41814787-AA
Procedure using the SIMATIC memory card
Use the SIMATIC memory card to read out the service data if communication with the CPU
is not over the Ethernet. In all other cases, read out the service data using STEP 7.
The procedure using the SIMATIC memory card is more time-consuming than the other
options for reading out the service data. You must also ensure before reading out that there
is sufficient memory space on the SIMATIC memory card.
Proceed as follows for the R/H-CPU to read 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 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. 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.
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 a note on the error that occurred in the
DUMP.S7S folder.
