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

    Yes, you may learn an activity by hearing others talk about it, or by watching others do it. But, your learning will be at its best if you yourself perform it. This would not only make you understand the underlying process, but also would help you practice and perfect the process. In the field of programming logic, this means writing many small programs or subroutines, and test the functionality by utilizing some simulator software. This is exactly what this e-book aims at, in the context of programming a 4-floor elevator using a Siemens Simatic Step7-300 & Logo PLCs. Assuming that you have a little background with PLCs, this book teaches you step-by-step on how to program the PLC to control all the mechanisms associated with an elevator. In general, what are the elevator features/components/modules that need to be programmed/controlled/managed? The basic requirements are to manage the UP/DOWN movement of the elevator-car, OPENING/CLOSING of the elevator-car, displaying the current position of the elevator-car or in which direction it moves, generating an alarm under abnormal conditions, etc. Also, the movement of the car or its doors should be smooth and at the required pace, and the parking of the car should occur at the specified levels. All these features and more can be achieved by programming the PLC appropriately, and wiring the PLC output with the respective output devices. In order to control or manage these output devices, what are the inputs that the PLC requires? 7 mechanical limit switches to detect the exact location of the car, 10 push-buttons to detect which keypad number is pushed to direct the elevator-car to that particular floor, 4 limit switches to control the sliding car door when it is closed or opened, and 4 limit switches to turn on an alarm when any of the floor doors is open accidentally. Hence control ladder logic program has to control a total of 25 mechanical limit switches in harmony! PLUS 24 output port terminals to control two DC motors, hoist and car door, 9 LED indicators to display which push-button key is depressed, 3 outputs to display the floor number where the car is parked at, 2 flickering LEDs to show direction of the car, 2 LED indicators to control car's inside lighting and alarm, and finally 1trigger signal output to activate the announcing system when the car reaches the destination floor.
Total of 21 outputs! With the help of relevant schematic/wiring diagrams, the book explains in detail how all these input and outputs can be controlled by the PLC to achieve the desired functional specifications. By becoming familiar with the solutions for implementing this project, the reader will acquire the knowledge, experience, and confidence to handle the PLC projects of even more complexities.

Topics covered in the text are:

Chapter 1: Presentation of the 4 floor Elevator with LOGO! software Comfort V. 7.0, Binary-coded decimal, Cabin display and Keypad hardware , Cabin sliding door dc motor controller schematic, Cabin lift dc motor controller , Project description, List of Equipment ,Main power supply circuit , Control hardware circuit, List of input / output and flags ,LOGO! Software Program.
Chapter 2: voltage divider circuit, installing an elevator floor announcing, The schematic of all other hardware used in this project is given: keyboard pad, DC motor controller .etc. if you wish, you can even build your own elevator hardware similar to ours or even tailor it to the one with more features you like. You can learn to master your programming knowledge just by simulating yours and checking out its performance and comparing it against my solution. This way you can improve your programming knowledge! And if you stuck at any step, you can check out my solution against yours and use the explanation to understand the reasoning behind.
Chapter 3: Connecting an HMI & AC motor drive to the PLC, and Explanation of the solution program.
Chapter 4: What is a "Human Machine Interface (HMI)" device? ,How to setup and connect a PanelMaster LCD (HMI) to the PLC ,A practical example of controlling a 3phase motor with a PLC, Developing our first control program for the HMI device ,Developing an "HMI" screen program for the elevator project.
Chapter 5: Variable frequency drivers (VFD), A little back ground on 3 phase motors and AC motor drivers, Relation between synchronous & rotor speed and the slip, Setting parameters of a typical AC motor driver. Questions and answers related to this project.

Please be informed that:
1- I shall email the content of the CD ROM (related to your purchase) to your inbox upon your request for immediate use after your payment is cleared.
2- All control software developed for this project is given when you purchase this item. You can upload the software to your PLC simulator and view the performance of the control software and LEARN. You can also build a simple hardware as shown in the video clip, and test the functionality of the control software in practice!
