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, as well as the appropriate symbol for the
delete criterion. Alarms and messages are displayed separately.
Standardized system of units: for lengths in millimeters (mm),
meters (m), etc.
Numerical Control: Numerical control (NC) includes all components of
machine tool control: → NCK, → PLC, → HMI COM.
Note: CNC (computerized numerical control) would be more
appropriate for the SINUMERIK 840D or FM-NC controls:
computerized numerical control.
Numerical Control Kernel: Component of the NC control, which
executes → part programs and essentially coordinates the
movements on the machine tool.
