GlossaryExtended Functions1110 Function Manual, 09/2009, 6FC5397-1BP20-0BA0MessagesAll messages programmed in the part program and → alarms detected by the system aredisplayed on the operator panel in plain text with date and time and the correspondingsymbol for the cancel criterion. Alarms and messages are displayed separately.Metric measuring systemStandardized system of units: For length, e.g. mm (millimeters), m (meters).MirroringMirroring reverses the signs of the coordinate values of a contour, with respect to an axis. Itis possible to mirror with respect to more than one axis at a time.Mode groupAxes and spindles that are technologically related can be combined into one mode group.Axes/spindles of a BAG can be controlled by one or more → channels. The same → modetype is always assigned to the channels of the mode group.Mode of operationAn operating concept on a SINUMERIK control. The following modes are defined: → Jog,→ MDA, → Automatic.NCNumerical Control: Numerical control (NC) includes all components of machine tool control:→ NCK, → PLC, HMI, → COM.NoteA more correct term for SINUMERIK 840D controls would be: Computerized NumericalControlNCKNumerical Control Kernel: Component of NC that executes the → part programs andbasically coordinates the motion operations for the machine tool.NetworkA network is the connection of multiple S7-300 and other end devices, e.g. a programmingdevice via a → connecting cable. A data exchange takes place over the network between theconnected devices.
