Solid state equipment has operational characteristics differing from those of
electromechanical equipment. “Safety Guidelines for the Application,
Installation and Maintenance of Solid State Controls” (Publication SGI-1.1)
describes some important differences between solid state equipment and
hard–wired electromechanical devices. Because of this difference, and also
because of the wide variety of uses for solid state equipment, all persons
responsible for applying this equipment must satisfy themselves that each
intended application of this equipment is acceptable.
In no event will the Allen-Bradley Company be responsible or liable for
indirect or consequential damages resulting from the use or application of
this equipment.
The examples and diagrams in this manual are included solely for illustrative
purposes. Because of the many variables and requirements associated with
any particular installation, the Allen-Bradley Company cannot assume
responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by Allen-Bradley Company with respect to use
of information, circuits, equipment, or software described in this manual.

Preface
Read this preface to familiarize yourself with the rest of the manual. This
preface covers the following topics:
•who should use this manual
•the purpose of this manual
•conventions used in this manual
•Allen–Bradley support
Use this manual if you are responsible for designing, installing,
programming, or troubleshooting control systems that use Allen–Bradley
small logic controllers.
You should have a basic understanding of SLC 500 products. If you do not,
contact your local Allen–Bradley representative for information on available
training courses before using this product.
We recommend that you review The Getting Started Guide for HHT, catalog
number 1747–NM009 before using the Hand–Held Terminal (HHT).
This manual is a reference guide for technical personnel who use the
Hand–Held Terminal (HHT) to develop control applications. It describes
those procedures in which you may use an HHT to program an SLC 500
controller.
This manual:
•explains memory organization and instruction addressing
•covers status file functions and individual instructions
•gives you an overview of ladder programming
•explains the procedures you need to effectively use the HHT
