Programmable Logic Controllers:
Programming Methods
and Applications
by
John R. Hackworth
and
Frederick D. Hackworth, Jr.
Therefore, the goal of this text is to help the student develop a good general
working knowledge of programmable controllers with concentration on relay ladder logic
techniques and how the PLC is connected to external components in an operating
control system. In the course of this work, the student will be presented with real world
programming problems that can be solved on any available programmable controller or
PLC simulator. Later chapters in this text relate to more advanced subjects that are
more suitable for an advanced course in machine controls. The authors desire that
this text not only be used to learn programmable logic controllers, but also that this text
will become part of the student’s personal technical reference library.
Readers of this text should have a thorough understanding of fundamental ac
and dc circuits, electronic devices (including thyristors), a knowledge of basic logic
gates, flip flops, and Boolean algebra, and college algebra and trigonometry. Although
a knowledge of calculus will enhance the understanding of PID controls, it is not
required in order to learn how to properly tune a PID. |
