Glossary
NC
Numerical Control component of the → CNC that executes the → part programs and coordinates
the movements of the machine tool.
Network
A network is the connection of multiple S7-300 and other end devices, e.g. a programming
device via a → connecting cable. A data exchange takes place over the network between the
connected devices.
NRK
Numeric robotic kernel (operating system of → NCK)
NURBS
The motion control and path interpolation that occurs within the control is performed based on
NURBS (Non Uniform Rational B-Splines). This provides a uniform procedure for all internal
interpolations.
OEM
The scope for implementing individual solutions (OEM applications) has been provided for
machine manufacturers, who wish to create their own user interface or integrate technology-
specific functions in the control.
Offset memory
Data range in the control, in which the tool offset data is stored.
Oriented spindle stop
Stops the workpiece spindle in a specified angular position, e.g. in order to perform additional
machining at a particular location.
Overall reset
In the event of an overall reset, the following memories of the → CPU are deleted:
● → Working memory
● Read/write area of → load memory
● → System memory
● → Backup memory
