Creating a Program

Arbitrary Controller Used in this Guide

In the following procedures, we have assumed that the controller you are

configuring in your program is a modular demo unit including the following

components:

• Rack 1746–A4, 4–slot rack

• Processor 1747–L511 in slot 0

• Input module 1746–IA4 in slot 1

• Input module 1746–IA8 in slot 2

• Output module 1746–OA8 in slot 3

The ladder program shown on page 3–11 contains I/O addresses that are

consistent with the configuration indicated above. If you are using some

other controller configuration, keep in mind that these addresses may not be

valid for your controller.

A program is always created offline. In creating the program, you will:

• Clear the memory of the HHT.

• Name the program and configure the controller.

• Enter a ladder program.

• Save the program in the HHT.

The abbreviated function keys that you will be encountering, both in this

Guide and on the HHT display, are explained in appendix C.
