Test and service functions
14.2 Reading/saving service data
Result: The CPU writes the service data to the DUMP.S7S directory 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
In function selection mode, a short button press < 3 seconds selects the next function
(currently only function "1" is available). The last function is "E", If you press the button for at
least 3 seconds, the function selection module is exited. The function selection mode is also
exited if no key is pressed for 10 seconds.
Reading service data during SIMATIC Drive Controller startup
1. Switch the supply voltage off at the SIMATIC Drive Controller.
2. Press and hold down the FUNCT button.
3. Switch the supply voltage on at the SIMATIC Drive Controller.
4. When the RUN/STOP LED flashes yellow and the ERROR and MAINT LEDs go out,
release the FUNCT button (after about 45 seconds). The save process begins. While the
function is active, 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 DUMP.S7S directory on the SIMATIC
Memory Card. If an error occurs during saving, the RUN/STOP LED lights up yellow and 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.
