Introduction to Programming
The control performs machining operations by executing a series of
commands that make up a part program. These commands are interpreted
by the control which then directs axis motion, spindle rotation, tool
selection, and other CNC functions.
Part programs can be executed from the control’s memory or from a CNC
tape. Programs on tape can be executed directly from the tape, or can be
loaded into the control and executed from memory.
This chapter begins with an explanation of CNC tape format. The
remainder of the chapter deals with the contents of a part program. It
explains blocks, words, G-codes, M-codes, etc.
For information on how to enter and edit part programs through the
keyboard, refer to chapter 5. For information on how to edit part programs
off-line and download them to the control, refer to chapter 6. For more
information on how to enter a part program from a peripheral device, refer
to chapter 9.
This chapter covers:
part program tape format
program configuration
block skip
using subprograms
word formats, functions, and descriptions
This section describes the format that the control requires for inputting and
outputting part programs from or to a tape device.
The control accepts:
ASCII format (RS-358B)
EIA-244-B format
Important: In addition to the control’s normal tape format (described in
this section), the control is also equipped to read and execute standard
Allen-Bradley 7320 and 7360 CNC tapes. Refer to Appendix D of this
manual for details.
