Chapter 5
Programming Examples
Read this chapter to familiarize yourself with how to use the advanced features of
your module for:
•
PID control
•
User-defined scaling
For information on how to use the Allen-Bradley Advanced Programming
Software (APS) to create ladder programs, see the Getting Started Guide For
APS.
Section 5.1
PID Control
Your input module was designed to work directly with the SLC 5/02, 5/ 03, and
5/04 PID instruction—without an intermediate scaling operation. Use the input
channel data as the process variable in the PID instruction.
Example:
Suppose your input module is in slot 3, and you have a level sensor
with a 4–20 mA range connected to channel 0. The following figures show you
how to use it for PID control:
