Structure of data management

Left-hand list box
6-4
The central elements of the data manager are presented in two boxes containing
NC files.
The left-hand list box contains the files belonging to a workpiece or another
directory on the hard disk. Only those files whose names comply with NCK
conventions are displayed in the left-hand list box. You select the workpiece or
directory in the combo box (single-line list box) displayed directly above the
left-hand list box. You can select the following directories in the combo box:
• Workpieces: Workpieces are directories where all the data required for the
production of a physical workpiece can be stored. When the workpiece is
created, the name of the workpiece (up to 8 characters are permitted) can be
freely assigned by the user. The names of workpieces stored on the hard
disk in directory C:\LOCAL are enclosed in square brackets [...].
Workpieces that are located in a directory other than C:\LOCAL display an
identifier after the square brackets that can be freely configured by the
machine-tool manufacturer. The identifier refers to a higher-level directory
(container for workpieces) that is either located on the local hard disk, the
diskette box or a remote computer.
Examples: [...]-network, [...]-flexos etc.
For workpieces that lie in a FlexOS directory, the workpiece names are
displayed together with their extension *.064.
The same higher-level directories (workpiece container) are displayed in
the DATA SELECTOR of the NCK as are displayed in the data
management display.
• MD user: This directory contains the manufacturer's machine data. The data
can be loaded into the NCK system memory during start-up.
• MD standard M/ MD standard T: These directories contain the standard
Siemens machine data for M and T controls.
• Cycles-user: This directory contains the cycles of the machine
manufacturer.
• Cycles-standard: This directory contains the turning and milling cycles
supplied by Siemens as standard with the control.
• Clipboard: The Clipboard is used to store files when data is input via the
serial interfaces. The files can be transferred from the Clipboard to the
desired directory. Section 6.2.6 "Data communication between the MMC
and peripheral devices" describes which of the individual data are stored.
