PID Programming Using RSLogix 500

PID Programming Using RSLogix 500This book teaches you how to effectively use the PID instruction in your ladder logic programming. Special focus is given to configuring the parameters for this useful instruction; as well as analog scaling, and the procedures used in tuning the control loop of an application process.Included are discussion and examples for some of the following topics:•The PID Control Algorithm and how it works.•Important PID Terminology & Definitions.•Programming & Setup of the RSLogix 500 PID instruction.•Understanding the Control Block Addressing.•Proper selection of the Operational Time Mode.•Setting an appropriate Loop Update Time interval.•Scaling for Process & Control Variables.•The Ziegler-Nichols Method of Tuning.The main objectives of this book are to provide a practical resource to those who may be new to the various methods used in process control applications.
