Notes:
1) You must read out register 7500 to register 7519 for a time to get the whole File Name .
Writing the path strings what you want to read in File Name register, and there are the following strings and XXX represents
the file number:
WFR configuration file: COMTRADE/WXXX.cfg
WFR data file: COMTRADE/WXXX.dat
If the WFR File Name are WAVE/W001.cfg and WAVE/W001.dat, and their string codes are
0x57,0x41,0x56,0x45,0x2F,0x57,0x30,0x30,0x31,0x2E,0x63,0x66,0x67 and
0x57,0x41,0x56,0x45,0x2F,0x57,0x30,0x30,0x31,0x2E,0x64,0x61,0x74 respectively.
2) File Offset register defines the offset of the first byte in the data buffer of the current file, it will automatically adjust the
file offset when read the File Offset register and it also can adjust to the specific offset by writing a relative number to File
Offset register.
3) It means that the file transfer completed when the Valid Byte Count is 0 and File Offset is equivalent to the file size.
4) File Data Buffer 1 to File Data Buffer 244 can be up to transfer 244 bytes data every time. And you also need to read out
all data buffer for a time to get the whole data.
