Chapter 13
Using Application Specific Instructions
13–20
To demonstrate the use of application specific instructions, this section
provides ladder rungs followed by the optimized instruction list of these
rungs. The rungs are part of the paper drilling machine application example
described in appendix E. You will begin a subroutine in file 4.
This portion of the subroutine tells the conveyor where to stop to allow a
hole to be drilled. The stop positions are different for each hole pattern
(3-hole, 5-hole, 7-hole), so separate sequencers are used to store and access
each of the three hole patterns.
Important: If you use a 16 I/O controller, only the 5 hole drill pattern can
be used.
