As the PDM is based on the Linux operating system, various and powerful file functions are available
to save and process data and parameters. Similar to a PC, files can be written to the different drives
(PCMCIA memory card or RAM or flash disk) and read from them. It is also possible to create and
read datasets in CSV format. This data can then be processed, e.g. in MS-Excel.
The file functions of the PDM can be widely used and combined in any way.
NOTE
The PDM360 is an embedded system which is comparable to a PC in many functions but does not
provide the same power reserves.

Therefore ensure the FBs are correctly and reasonably used!
Otherwise, negative effects on operation and system stability can occur.
