2.1.2 Files which can be Created on a Data Server
In the initial status, the maximum number of files which can be
created on a memory card on a Data Server is 2047 and the maximum
file size is 512 MB. Each folder is counted as one file.
The maximum number of files and the maximum file size can be
changed using NC parameter No. 930.
For details, see Section 2.2, "RELATED NC PARAMETERS," in Part
III, "SETTING."
2.1.3 Text Files and Binary Files
You can store the following two types of files on a memory card on a
Data Server: text files and binary files.
For a text file, memory operation and edit operation as well as DNC
operation can be performed by selecting it as a main program.
For binary files, only DNC operation is available, but binary input
operation in the high-speed remote buffer A format is available.
If NC data other than an NC program is not handled as a binary file, it
may not be able to be input or output correctly. NC data punched and
stored on a memory card on a Data Server from the CNC is
automatically handled as a binary file. A file to be transferred from a
personal computer to a memory card on a Data Server must be
specified explicitly as a binary file.
More specifically, for GET operation on a Data Server operation
screen, you can use soft key [GET] or [BGET] to specify whether to
handle the file as a text file or a binary file.
When the Data Server is used as an FTP server, you can execute an
ASCII (text file) command or a BIN (binary file) command on your
personal computer (FTP client) to specify whether to handle the file as
a text file or a binary file.
NOTE
An NC program stored as a text file is converted to
an editable file format so that the file can be edited
on the CNC. For this reason, when a text file is
read from the host computer to the memory card
on the Data Server, then the file is transferred to
the host computer, binary compatibility can no
longer be maintained.
