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.
