6.1 Details of functions
The user can perform the following procedures for CompactFlashTM cards using applied instructions for the
CF-ADP.
• Creating FIFO function files inside the CompactFlashTM card.
(Only one pattern is available for FIFO function files. Multiple FIFO function files are created automatically
with a predetermined file name. If the created FIFO function files exceed the allowable capacity, old files
are deleted. The FIFO function is executed in units of files.)
• Creating files inside the CompactFlashTM card.
(Up to 63 files can be created.)
• Deleting specified files stored in the CompactFlashTM card.
• Writing bit data, word data, double-word data, floating point data and character string data to a specified
file stored in the CompactFlashTM card.
Data can be written to the CompactFlashTM card using the following two methods:
- Data is directly written to the CompactFlashTM card without using the internal buffer. Up to 254 data
points can be written to one line.
- Data is collected in the internal buffer. When the internal buffer becomes full, data is written to the
CompactFlashTM card. Up to 254 data points can be written to one line.
• Forcibly writing data of a specified file stored in the internal buffer to the CompactFlashTM card.
• Reading the number from the final line in a specified file stored in the CompactFlashTM card.
