Memory dump file
This file stores data that is collected through memory dump (collection result by memory dump). Data collected by one
execution is saved in one file. The memory dump file is saved in a binary format and stored under the "MEMDUMP" folder.
Save file name
The file name can be arbitrarily set within a range of 64 characters (extension and period included) together with an auto-
assigned number (00 to 99). Specify the save file name in the memory dump settings. (

*1 Between a specified file name (MEMDUMP) and an auto-assigned number (00), the single-byte underscore (_) is added.
When the memory dump function is registered, the debug folder (DEBUG (fixed)) and the memory dump folder (MEMDUMP
(fixed)) are created in the SD memory card. The memory dump file (result file) is stored in the memory dump folder. One folder
can contain a maximum of 100 files. If any file does not exist in creating a save file, the file with the number 00 is created. If
any file already exists in creating a save file, the behavior is as follows:
*2 If the corresponding file number is 99, a file with file number 00 is created.

assigning the number obtained by adding 1 to the number of the file where the creation date and time is
the latest.
For 100 (maximum) Deletes the file where the creation date and time is the oldest and creates a new file using the deleted number as it is.
