11 Performing a Backup Operation
Precautions
Notes related to transferring in general
(1) Depending on the type of file, some data cannot be transferred during automatic operation. Do not transfer during
automatic operation.
(2) When the capacity of the transfer destination is reached during file transfer, only the data transferred up to that point
is registered as a file, and an error will occur.
(3) During input to the NC memory or comparison, if the file format size on the NC memory side differs from the other
side file format size (when the maximum number of registrations differs between the NC memory and the other side),
processing is carried out matched to the smaller size.
(Example 1) If a format size of 200 files is input for a format size of 1000 NC files, 200 files are registered.
(Example 2) If 1000 files are input to the NC that formatted for 200 files, the files up to the 200th file can be registered
and an error message appears. (The remaining files are not registered.)
(4) Do not perform any file operation on the transfer source and destination files during the file transfer. The file may be
damaged with the file operation.
Notes when transferring machining program files
(1) The transfer speed is slower if there are many registrations.
(2) The size of one block of the machining program should be 250 characters or less.
(3) The characters that can be used for the file name and directory path are 1-byte number, 1-byte capital alphabetical
letters, and 1-byte symbols recognized by the system.
Note that the following characters cannot be used.
|, /, :, "," (comma), *, ?, ", <, >, a to z (small letters), space
Up to 32 characters are allowed for the file name to create in or transfer to NC memory.
(4) If the file whose name includes lower case alphabet is transferred to NC memory, the lower case letter will be con-
verted into the capital letter.
(5) When the MTB macro and fixed cycle program are input to NC memory, change the program type with the parameter
"#1166 fixpro". Also, set in the Input/Output screen as follows:
Device: Memory, Directory: Program
(6) With machining program created before the MELDAS500 Series, "EOB" is registered as "LF". However, "EOB" will
be converted to "CR LF", and the number of characters will increase in this Series. Thus, when all of the machining
programs output from an MELDAS500 Series or earlier NC, having the same specifications as the maximum memory
capacity, are stored in this Series, the memory capacity may be exceeded.
(7) If the file to be transferred (input) is running or in "program restarting" mode, the operation message "Executing auto-
matic operation" or "Program restarting" is displayed, and the file will not be transferred (input).
(8) When the parameter "#8936 Delete leading 0" is set to "1", the file consisting only of numerical figures will be trans-
ferred with the "0" at the head deleted. For details, refer to "4.8.6 Leading Zero".
(9) When the multi-part system program management is valid (#1285 ext21/bit0 =1) and "#1285 ext21/bit2" (Multi-part
system program generation and operation) is set to "1", the file transfer to the device [Memory] from the other device
is executed with the machining programs in only displayed part system. In other cases, the machining programs are
transfered across all part systems in batch.
(10) When the multi-part system program management is valid (#1285 ext21/bit0 =1) and "#1286 ext22/bit5" (Selection
of multi-part system program input/output method) is set to "1", the file transfer from the device [Memory] to the other
device is executed with the machining programs in only displayed part system. In other cases, the machining pro-
grams are transfered across all part systems in batch.
(11) The transfer range from the external device to NC memory will change depending on the value set in the parameter
"#19006 EOR Disable".
<When the parameter "#19006 EOR disable" is set to "0">
The head line will not be transferred.
Up to "%" in the second line onward will be transferred, and data after "%" will not be transferred.
If there is no "%", all data will be transferred.
<When the parameter "#19006 EOR disable" is set to "1">
All file contents will be transferred.
