(d) Precautions for writing files
(e) Precautions for deleting files
USING BUILT-IN
• Operation to overwrite an existing file cannot be performed. Either delete the
file using a file delete command (delete, mdelete) or rename the file using a
file name change command (rename) before writing the file.
• Files whose attribute is read-only or files which are locked by other devices/
functions cannot be written. If files are written, a write error occurs.
• File transfer (writing files) cannot be executed when a write-protected
memory card is used. If files are written, a write error occurs.
• When a file is written, a temporary file (FTP_I***.TMP) is created
automatically. The name of this file is changed to the name of written file upon
normal completion. However, if the power failure or reset of the CPU module
occurs during the file write, this temporary file may remain. If this occurs,
delete the temporary file.
• When file registers are used in the standard RAM or SRAM card, change the
CPU status to STOP first, and then write /delete files to/in these drives.
• When file registers used in the standard RAM or SRAM card are set as auto
refresh devices, do not write/delete files to/in these drives.
• If large-capacity files are written to the ATA card during RUN, a load on write
processing increases and a communication error may occur. Change the
CPU status to STOP to write large-capacity files.
• The timing for deleting files is to be arranged by the user considering the
overall system, including Built-in Ethernet port QCPU and GX Developer.
• Files whose attribute is read-only or files which are locked by other devices/
functions cannot be deleted. If files are deleted, a delete error occurs.
• Deleting files cannot be executed when a write-protected memory card is
used. If files are deleted, a delete error occurs.
