(2) List of transferable files
Table7.7 lists the transferable files using the file transfer function.
: Transferable : Not transferable
* 1 : A file for reading/writing data by a sequence program using the following instructions:
• SP.FREAD (Batch-reads data from the specified file in the memory card.)
• SP.FWRITE (Batch-writes data to the specified file in the memory card.)
For details on the SP.FREAD/SP.FWRITE instructions, refer to the following manual.
QCPU (Q mode)/QnACPU Programming Manual (Common Instructions)
* 2 : Writing files to the program memory is enabled only when the CPU module is in the STOP status.
* 3 : Write destination is the program cache memory. The user should back up files using the "pm-
write" command as required. ( (5) in this section)
* 4 : The number of files written using the File transfer function (FTP) is up to the number described
below.
[The maximum number of files can be stored in the corresponding drive -1]
