16.2 Reading/saving service data
3. Switch the supply voltage on at the SIMATIC Drive Controller.
4. To start the saving process, release the FUNCT button as soon as the 7-segment display
flashes at least once (approx. 1 to 2 seconds after POWER ON).
The save process only begins after about 45 seconds and is indicated by a yellow flashing
RUN/STOP LED. The ERROR and MAINT LEDs are off. As the save process progresses, the 7-
segment display shows "d" (DUMP) and the ACT LED flickers. After completion of the
saving process, the 7-segment display shows "0".
Result: The CPU writes the service data to the folder DUMP.S7S on the SIMATIC Memory Card.
If an error occurs during saving:
• The RUN/STOP LED flashes yellow (for STOP) or green (for RUN) depending on the
previous operating state
• The ERROR LED flashes red
In the event of an error, the text file in the DUMP.S7S folder contains information about the
error that has occurred.
Note
Procedure using the SIMATIC Memory Card
Instead of using the FUNCT button, you can also initiate saving the service data using the job
file S7_JOB.S7S and the DUMP string.
To do so, use an editor to overwrite the PROGRAM entry with the DUMP string.
To ensure that the file size is exactly 4 bytes, do not use any spaces/line breaks/quotation
marks.
If you read out the service data (with the entry String DUMP), the SIMATIC Drive Controller
does not start.
You must change the entry back to PROGRAM once the function has been executed.
Procedure using the Web server
Requirement: Access to the Web server has been activated for the interface used.
Proceed as follows to read service data using the Web server:
1. Open a Web browser that is suitable for communication with the SIMATIC Drive Controller.
You can find additional information in the Web server
(https://support.industry.siemens.com/cs/ww/en/view/59193560) function manual.
2. Enter the following address in the address bar of the web browser:
https://<CPU IP address>/save_service_data, e.g. https://172.23.15.3/save_service_data
