Glossary
Messages
All messages programmed in the part program and → alarms detected by the system are
displayed on the operator panel in plain text with date and time and the corresponding
symbol for the cancel criterion. Alarms and messages are displayed separately.
Metric measuring system
Standardized system of units: For length, e.g. mm (millimeters), m (meters).
Mirroring
Mirroring reverses the signs of the coordinate values of a contour with respect to an axis. It is
possible to mirror with respect to more than one axis at a time.
Mode of operation
An operating concept on a SINUMERIK control. The following modes are defined: → Jog,
→ MDA, → Automatic.
NC
Numerical Control: Numerical control (NC) includes all components of machine tool control:
→ NCK, → PLC, HMI, → COM.
Note
A more correct term for the SINUMERIK 802D sl control would be: Computerized Numerical
Control
NCK
Numerical Control Kernel: Component of the NC that executes the → part programs and
basically coordinates the motion operations for the machine tool.
Network
Thanks to the integrated network adapter, the control system is network-capable. The
following connections are possible:
● Peer-to-Peer: Direct connection between control system and PC using a cross-over cable
● Twisted Pair: Incorporation of the control system into an existing local network using a
450
patch cable.
