2.13.3 G Functions
General
The G functions programmed in the part program, ASUB or synchronized actions are
channel specifically transferred from the NC to the PLC:
• G functions from channel 1: DB21
• G functions from channel 2: DB22
• etc.
The signal length is one PLC cycle.
POWER ON
After POWER ON, the value zero, i.e., active G groups undefined, is specified in the NC/PLC
interface for all G groups.
Part program-End or Abort
After part program end or abort, the last state of the G group is retained.
NC-START
After NC-START the values specified in the machine data:
MD22510 $NC_ GCODE_GROUPS_TO_PLC
specified 8 G-groups corresponding to the basic setting done via the machine data, as well
as the values programmed in the part program, are overwritten.
