File 4, Rung 6
Signals the main program (file 2) to initiate a drilling sequence. The
high–speed counter has already stopped the conveyor at the correct
position using its high preset output pattern data (clear O:0/0). This
occurred within microseconds of the high preset being reached (just prior
to entering this high–speed counter interrupt subroutine). The drill
sequence subroutine resets the drill sequence start bit and sets the
conveyor drive bit (O:0/0) upon completion of the drilling sequence.
