GlossarySpecial functions: AppendixFunction Manual, 11/2006, 6FC5397-2BP10-2BA0 21Coordinate systemSee → Machine coordinate system, → Workpiece coordinate systemCPUCentral processing unit, see → Memory-programmable controlC-SplineThe C-Spline is the most well-known and widely used spline. The transitions at theinterpolation points are continuous, both tangentially and in terms of curvature. 3rd orderpolynomials are used.Data Block1. Data unit of the → PLC that → HIGHSTEP programs can access.2. Data unit of the → NC: Data modules contain data definitions for global user data. Thesedata can be initialized directly when they are defined.Data wordTwo-byte data unit within a → data block.Diagnose1. Operating area of the control.2. The control has both a self-diagnostics program as well as test functions for servicingpurposes: status, alarm, and service displaysDimensions specification, metric and inchesPosition and pitch values can be programmed in inches in the machining program.Irrespective of the programmable dimensions (G70/G71), the controller is set to a basicsystem.DRFDifferential Resolver Function: NC function which generates an incremental work offset inAutomatic mode in conjunction with an electronic handwheel.DriveThe SINUMERIK 840D control system is digitally connected to the SIMODRIVE 611converter system over a high-speed digital parallel bus.
