SINUMERIK 880 (PJ)
NC mode
Interface module for MPC bus, inserted in the central
controller
Individual bit or data that can be evaluated or modified by
the PLC user program. Serves as a user interface to a
separate SINUMERIK 880 unit, e.g. an NC channel,
the operator panel or another PLC CPU. The interface
signals are located in data blocks or the I/Q/F areas.
The interpolator calculates the path points for machining
the workpiece until the destination point programmed in
the part program. The programmed preparatory functions
are taken into account. Each NC channel has its own
interpolator.

Bus in the central controller which links the individual
CPUs of the separate areas (NC, PLC, COM) to the
link RAM
Memory area used for communication between the NC,
COM and PLC areas. Located on a memory module on
the link bus which can be accessed by the CPUs of the
NC, COM and PLC areas (dualport or multiport RAM).
Bus in the central controller which links the individual
CPUs to the modules to which only the CPU concerned
has access
I/Os accessible via the local bus of the PLC; see
Section 1
See Computer Link documentation
PLC mechanism which influences the M signals in the
PLC according to the M functions contained in the part
program
Miscellaneous function for NC part programs. Some M
functions have fixed meanings, others can be freely
defined.
Signal in data blocks which is influenced by M
functions contained in the NC part program
Word (parameter) in the part program for a
miscellaneous function
