-> NC
The high-level language offers: -> user variables, -> predefined user
variables, -> system variables, -> indirect programming,
-> arithmetic and angular functions, -> relational and logic operations,
-> program jumps and branches,
-> program coordination (SINUMERIK 840D), -> macros.
Component of the NC control for the implementation and coordination
of communication.
Outline of a -> workpiece.
See -> machine coordinate system, -> workpiece coordinate system
Central Processor Unit, -> PLC
Protected subroutine for the execution of a repeated machining
procedure on the -> workpiece.
Using these special setting data the cycle parameter calculation can
be varied.
The available cycles are listed in menu "Cycle support" in the
"Program" operating area. Once the desired machining cycle has been
selected, the parameters required for assigning values are displayed
in plain text.
A data unit on the -> PLC which can be accessed by -> HIGHSTEP
programs.
A data unit on the -> NC: Data modules contain data definitions for
global user data. These data can be initialized directly when they are
defined.
PCIN is an auxiliary program for transmitting and receiving CNC user
data, e.g. part programs, tool offsets, etc. via the serial interface. The
PCIN program can run under MS-DOS on standard industrial PCs.
