Parameter data record 1990

During operation of the TM NPU, (internal) module states are written to a ring buffer in the
RAM. You can call up this information about the internal state of the TM NPU for analysis, e.g.
in case of an error.
The data is written to the SIMATIC Memory Card and can be forwarded to Technical Support.
Functionality
If no service data is present on the SIMATIC Memory Card yet, the "/servicedata" folder with
the "servicedata.dummy" file (2 MB) is created automatically. The "servicedata.dummy" file is
overwritten when the service data is requested for the first time.
To request the data, write the parameter data record 1990 to the TM NPU.
The requested information is stored in a file in the "/servicedata" folder.
The file is named according to the following schema: servicedata_$counter(0...3
char)_$user(0...29 characters).bin.
Example: servicedata_0001_usertriggered.bin, servicedata_0002_usertriggered.bin.
Existing data is retained.
NOTE
If a communication error occurs, this function is no longer available.
