PLC programming
Posted: Sun Oct 30, 2016 5:02 pm
A programmable logic controller, PLC, or programmable controller is a digital computer used for automation of typically industrial electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many machines, in many industries.

There are famous controllers like Allen-Bradley from Rockwell Automation and SIMATIC STEP 7 from Siemens. The architecture is the same LADDER language, but slightly differences in addressing the bits for the input, output, Latching/Unlatching, and Set/Reset the coil etc.
I have attached a book , and a website where you can practice your programming skills online by simulating your LADDER.
Try to program this:
Suppose we have an AC motor, and we want to control it by using push buttons (Start, Stop), write a program that will be "downloaded" to the controller to control the motor.

Note:
- Start-button is a Normally Open button
- Stop-button is a Normally Closed button
