Rung 4:6

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.
