Beginner's Guide to PLC Programming

For a beginner who wants to learn PLC programming is strongly recommended to use a guide or tutorial. Beginner's guide to the PLC programming courses can be conducted at institutions of learning PLC programming, or you can be taught himself by reading a book or eBook PLC programming tutorials or you can also get access to an online course to let you see the PLC programming in action. You learn by watching.

Beginner's Guide to PLC Programming will learn things like the following:
• Define the most commonly used terms, such as rung, bit, input, output, etc.
• Learn relay ladder logic in simple, easy to understand terms
• Learn Machine Diagnostics and how to use them in your PLC program
• Learn the basic knowledge you need to be a top-notch PLC programmer
• Introduce to PLC control, and how it is used in plant automation

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. This PLC tutorial usually explains everything you need to know to get a solid understanding of PLCs.

To the beginner, some courses or online tutorial may be 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.

Sequence PLC Programming for Traffic Light PLC Program :

Step 1 :
a. If Switch ON/OFF = ON Then System Traffic Light is Active.
b. If Switch ON/OFF = OFF Then System Traffic Light is Inactive.


Step 2 :
a. IF Green color lights in Position A ( No.2) = ON then Red Color Lights in Position B,C, AND D = ON And Timer0 Activated.
b. IF Timer0 = ON then Green color lights in Position C ( No.6) = ON And Red Color Lights in Position A,B, AND D = ON And Timer1 Activated.
c. IF Timer1 = ON then Green color lights in Position D ( No.8) = ON And Red Color Lights in Position A,B, AND C = ON And Timer2 Activated.
d. IF Timer2 = ON then Green color lights in Position B ( No.4) = ON And Red Color Lights in Position A,C, AND D = ON And Timer3 Activated.
e. IF Timer3 = ON then Green color lights in Position A ( No.2) = ON And Red Color Lights in Position B,C, AND D = ON And Timer0 Activated.
f. Continuously to Step 2.b
g. Timer0,1,2,3 set to 2 minutes
