4.3 Parameter Transfer between PLC and NC
NC $
$$
$ PLC (16-bit registers)
They are loaded by the NC transferring through them the desired (target) values to the PLC.
Put in brackets are the data formats of the register contents.
RH000 speed programmed to address "S"
RH001 tool number programmed to address "T" or tool pot number.
RH002 programmed spindle command programmed to M3, M4, M5 or M19.
RH003 programmed coolant codes M8 or M9.
RH004 programmed range codes M11, ..., M18.
RH014 NUMERIC ENTRY (2-byte hexa).
RH015 START/STOP (21H=START, 20H=STOP) (2-byte hexa).
RH016 SOFTKEY (0-7=soft keys, 2FH=pager) (2-byte hexa).
RH017 JOG keys (2-byte hexa).
RH040 actual spindle speed measured from the spindle encoder.
PLC $
$$
$ NC (16-bit registers)
The values issued by the PLC (and updated) have to be written in those registers. They are
received and displayed by the NC.
RH050 effective speed issued for the spindle.
RH051actual tool number or tool pot number.
RH052 actual spindle code (M3, M4, M5, M19).
RH053 the current coolant code (M8, M9).
RH054 current state of the range selector (M11, ..., M18).
