How to Program a PLC (Programmable Logic Controller)
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®, Texas Instruments®, 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. It will help you in your current job or help get you the job you want.
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 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 more than an introduction to PLCs. 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 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
• give you the "13 Marks of a Well Written Program"
• explain Machine Diagnostics and how to use them
The ebook is the result of 16 years of experience in PLC programming and electrical design and engineering. It summarizes dozens of techniques that are needed to write a solid PLC 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.
With drawings and illustrations, you are guided through the steps of writing a PLC program. Here is a small excerpt from the tutorial:
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.
Here is more of what you will get:
It's best to start a program by evaluating any safety switches and setting a master bit. Then, you can use this bit throughout the program to turn off outputs immediately when the machine shuts down.
In this case, a latch is used to set an internal “System Running†bit. If the emergency stop is clear, and the machine guard is in place, and there is no system fault the operator may press the start button to set the latch. If the stop button is pushed or a previous conditions ceases to exist, the “System Running†latch will drop out.
Most of the time, the order of the bits in a rung doesn't matter in relay ladder logic. We could have rearranged any of the bits in this rung, though we would still have to put the latch around the Start pushbutton. The PLC wouldn't care and the output coil would still respond the same. However, to make the rung easier to read, I try to place bits from left to right in order of importance. If the E-Stop is not cleared, then nothing else should matter anyway. Having the safety guard in place is more important than a system fault. Now, if those requirements have been met, we can press the start button. And we don't care about the stop button until we have pushed the start button.
altIn addition to the ebook, you also get access to an online course to let you see ladder logic in action. You learn by watching.
The online tutorial runs for about an hour. You can pause the course, review the material and put extra time into particular sections as you wish. It is available 24 hours a day, 7 days a week.
You may also download the course to your computer so that you view the course when you are offline.
PLC training has never been more readily accessible. It's like having your own PLC tutor!

"The book was very easy to understand - now I am able to have an intelligent conversation with the programmers and know what they are talking about."
"I would recommend this to anyone who wants to understand the basic concepts of programming a PLC."
Neal Babcock has a degree in Electrical Engineering and has written and maintained a number of PLC programs used in the semiconductor, automotive, health care and aviation industries.
