There is a quotation which was originally stated by Confucius, I would like to present it here as a very practical statement on how the human mind approaches the learning process:
I hear, and I forget. I see, and I remember. I do, and I understand --- Confucius
All this means is the best way to understand anything is to get your hands on it and actually experiment with it. In computer programming this means writing many small programs and using some kind of simulator software to test programs' functionality. The book provides both fundamental and cutting-edge coverage on PLCs. It explains most basic to intermediate and advance instructions through
many worked-out examples and explanations of the solutions.
Many companies have developed software for programming PLCs. For purposes of illustrating and practicing how the software works, we have selected S5w software created by IBH Softec for programming Simatic S5family of programmable controllers. This software is a Demo Version (Freeware), therefore you may copy it from web yourself and use it to simulate your programs. The
software is a Microsoft Windows base and is very user friendly.
Using software to simulate small programs, makes the learning process very interesting and fun!!.
We have also included many Tutorial circuits and programs for Siemens S5 family of PLCs program and exercises completely worked out with solutions therefore, you may just type each in and run it via a simulator to understand the concept of each subject even better
