Programming Overview
This chapter explains how to use the MicroLogix 1000 HHP to program the
micro controller. Read this chapter for basic information about:
•
principles of machine control
•
understanding file organization
•
understanding how programs are stored and accessed
•
addressing data files
•
applying logic to your schematics
•
a model for developing your program
The controller consists of a built-in power supply, central processing unit
(CPU), inputs, which you wire to input devices (such as push buttons,
proximity sensors, limit switches), and outputs, which you wire to output
devices (such as motor starters, solid-state relays, and indicator lights).

You enter a logic program into the controller using the HHP. The logic
program is based on your electrical relay print diagrams. It contains
instructions that direct control of your application.
