PLC training and PLC tutorial that is easy to understand
Look around in any modern manufacturing facility and you will find PLCs, or Programmable Logic Controllers. You have seen all the names; Allen-Bradley®, Modicon®, Automation Direct®, Siemens® and so on. Large companies and small companies use these types of computers to automate and control their manufacturing processes.
Understanding how these PLCs work is very important to anyone who works with industrial equipment. PLC training and ladder logic training will help you in your current job or help get you the job you want. Browse CareerBuilder sometime and find all the companies looking for people who understand PLCs, PLC control and ladder logic.
Unfortunately, learning what makes a PLC tick and how to program one is usually expensive and is normally done on somebody else’s schedule.
If you understand how a PLC works, you can:
• create PLC programs and edit existing relay ladder logic
• make yourself worth more to your company
• communicate your ideas better to your co-workers
If you have always been a bit mystified by these “black boxes”, then this PLC training manual is for you.
This PLC tutorial explains everything you need to know to get a solid understanding of PLCs and provides the most cost-effective PLC training available today.
This ebook is a PLC tutorial that is more than an introduction to PLCs and PLC control. It contains real world examples that are a result of 16 years of PLC programming experience. It contains tips and routines you can start using immediately to write your own PLC program.
To the beginner, it is more valuable than the thick and complex books written by college professors. They cover functions and algorithms you may never use. After wading through one of these, you still might not know how to turn on a motor.
The “Beginner’s Guide to PLC Programming” makes learning ladder logic easy. And it is written in plain English.
“Beginner’s Guide to PLC Programming” will:
• define the most commonly used terms, such as rung, bit, input, output, etc.
• explain relay ladder logic in simple, easy to understand terms
• give you the “13 Marks of a Well Written PLC Program”
• explain Machine Diagnostics and how to use them in your PLC program
• save money and save time
• teach you the basic knowledge you need to be a top-notch PLC programmer
• introduce you to PLC control, and how it is used in plant automation
The ebook is the result of many years of experience in PLC programming, electrical design and engineering. It summarizes dozens of techniques that are needed to write a solid program.
It has easy to understand text with relay ladder logic routines that can be used again and again.
You learn how to use coils, contacts, internal bits, latches, timers, safety rungs, addressing, inputs, outputs . . . and more.
It doesn’t matter whose PLC you will be using; all graphical-based PLC programming uses Ladder Logic. Rockwell Automation (Allen-Bradley), Siemens, Modicon, or whoever, all use ladder logic. Until you understand ladder logic and the concepts of PLC control, you won’t be able to program these PLCs.
The good news is that ladder logic, and programmable logic control, is not that hard to understand. There are just a few essential concepts that you need grasp, and we will share those with you.
We know you are busy. This tutorial lets you learn when you have the time.
The ebook can be downloaded to your computer, and the tutorial can be viewed online at any time. You can learn at your own pace.
Sample Ladder Logic
With drawings and illustrations, you are guided through the steps of writing programs for PLCs and understanding PLC ladder logic. Here is a small excerpt from the book:
After the part has been moved into position, the PLC will instruct the machine to clamp the part in place. This is done by energizing OUTPUT11, which turns on solenoid SOL11. The solenoid moves the actuator, which holds the part. You will notice that the branch in the rung contains the logic to provide a manual method of holding the part for machine set-up and maintenance.
“The book was very easy to understand – now I am more able to know what the programmers are talking about.”
Tom Wilson, Mechanical Designer
“I would recommend this to anyone who wants to understand the basic concepts of programming PLC ladder logic.”
Ralph Dempsey, BSEE Electrical Engineer
