9.2.1 Operation details
• When X000 turns ON, the following file is created.
If a file whose file ID is "1" already exists in the CompactFlash
TM
card, file creation and data name writing
are aborted.
- File ID = 1
- File name = DWORD_01
- Data type = Decimal type (32 bit)
• When X001 turns ON, 10 data points of 32-bit decimal type stored in D400 to D419 are written additionally
to the internal buffer of the CF-ADP. When the number of times of additional writing to the internal buffer
reaches 10, later data will be written additionally to the file "DWORD_01" stored in the CompactFlash
TM
card.
• When X002 turns ON, 10 data points of 32-bit decimal type are read from the final line in the 32-bit decimal
type file "DWORD_01".
Data reading should be executed after data writing.
• When X003 turns ON, the 32-bit decimal type file "DWORD_01" is deleted.
