(4) File writing
• An existing file cannot be overwritten.
Delete or rename an existing file with the file delete command (delete, mdelete) or the file rename command
(rename) before writing files.
• A read-only file or a file locked by the function except for FTP cannot be written. If attempted, a write error
occurs.
• A file cannot be transferred when the memory card or SD memory card used is protected. If attempted, a
write error occurs.
• A temporary file (FTP_I***.TMP) is automatically created at a file writing. The file is renamed the write target
file name when a writing is completed, however, the temporary file may remain if the CPU module is
powered off or reset during a file writing. In this case, delete the temporary file.
• Before writing or deleting data to the file register in the standard RAM, set the CPU module to STOP.
• When the file register in the standard RAM is set as an auto refresh device, do not perform any writing or
deletion to the corresponding drive.
• When writing a large file to a memory card or SD memory card, set the CPU module to STOP. If writing is
performed in RUN state, a communication error may occur.
(5) File deletion
• The timing for deleting files must be determined by the user, considering the overall system including the
CPU module and programming tool.
• When a memory card or SD memory card is protected, no files can be deleted. An error occurs if a file is
deleted.
