FNC 300 – FLCRT / File create
•check
Outline
The FLCRT instruction creates a file inside the CompactFlash
TM
card mounted in the FX
3U
-CF-ADP. When executed
after creation of a new file, the FLCRT instruction checks the association with the file ID, and evaluates it.

Explanation of function and operation
1. 16-bit operation (FLCRT)
• When the file ID is "K0"
When
is "K0", the FLCRT instruction creates a FIFO file.
When the PLC creates two or more files for FIFO file, and executes FIFO (first in, first out) in units of files.
The PLC keeps the latest file, and deletes older files so that the total capacity of FIFO files and other files does not
exceed the specified capacity.
The PLC keeps the latest file, and deletes older files so that the total capacity of FIFO files and other files does not
exceed the specified capacity.
• When the file ID is "K1" to "K63"
When
is "K1" to "K63", the FLCRT instruction creates a file having the specified file name.
Sequence programs use the file ID for specifying a file. Accordingly, each file name saved in the CompactFlash
TM
card is associated with the file ID, and controlled by the file ID table.
If a file having the specified file name already exists and is registered in the file ID table, the PLC finishes the
FLCRT instruction without executing any processing.
If a file having the specified name already exists but is not registered in the file ID table, the PLC only registers the
existing file to the file ID table.
If a file having the specified file name already exists and is registered in the file ID table, the PLC finishes the
FLCRT instruction without executing any processing.
If a file having the specified name already exists but is not registered in the file ID table, the PLC only registers the
existing file to the file ID table.
