A quick introduction to the course.
Before we start programming we need to know what a plc is, and what it does.
In this lesson we walk through how to download the software onto our computer and smartphone.
We discover our first plc program in this lesson, in the simulator an input brings on an output.
In this lesson we learn how to add rungs to our first program.
A scan cycle is how a plc checks the status of inputs, outputs and logic functions in its program. In this lesson we start to learn how scan cycles work.
We continue learning about plc scan cycles in this lesson, we discover what happens when an input goes true.
In this lesson we learn how to build a hold in program, one of the most commonly used rungs in ladder logic.
We learn how to assign tags in this lesson, tags can be used make programs easier to understand.
In this lesson we go through a full scan cycle of a hold in program, we see how the addresses are updated when the start and stop buttons are pressed.
If two coil functions point to the same address we learn which one overrides the other and why.
In this lesson we look at the rules we need to follow to complete the 2 stage motor programming challenge.
If you completed the programming challenge on your own - well done.
If not don't worry - we will look at the solution in this lesson.
learn how to toggle 2 outputs on and off with a flip switch.
Discover how level switches can control the amount of liquid in a tank.
Start building a one shot program.
Use our one shot program to see learn about 2 new functions.
Let's learn about binary code in this lesson.
An introduction to the files that the PLC uses to store the 1s and 0s from the inputs, outputs and functions in the program.
PLCs use a file (or sometimes more than one file) that stores single bits of information.
Build a program that sees when an orange juice bottle is filled and moved down the production line.
Reject the empty bottle in this lesson.
Let's look at the most common numbering data types used in PLC programming.
What is the hex button for?
Learn how to count stuff in this lesson!
Apply what we learnt in the previous lesson to our filling line program - count the orange juice bottles.
Learn how to add comments to the ladder.
Learn how to use the on delay timer in this lesson.
Learn how to use the off delay timer in this lesson.
In this lesson we look at the rules we need to follow to complete the timed motors programming challenge.
In this lesson we start building the program for the timed motors programming challenge.
Let's see if you completed the challenge and got the program working.
Learn how to adjust the timer preset in with push buttons.
Create a matrix that we will follow to program a set of traffic lights.
Add a recycling timer to our program.
Learn how we will bring on the first stage of our traffic light program.
Add the rest of the stages to the traffic light program.
Learn how to re-write the traffic light program using sequencing.
Finish the sequencing for our traffic light program.
NO EXPENSIVE HARDWARE NEEDED!
All you will need is a windows10 computer with a MINIMUM DISPLAY RESOLUTION OF 1920 x 1080 (Full HD) / or an android device.
In this course you will learn how to program PLCs with ladder logic by using the 'PLC ladder simulator 2' software application.
The software simulates the hardware inputs & outputs of a PLC which allows you to write and fully test your own PLC programs right there on your screen.
As well as learning all the functions available to you in the free version of the simulator, together we will construct and test real world PLC programs - everything that I do on my screen, you will do on your screen too!
In this course you will learn about:
Scan cycles
Creating tags
Functions
Counters
Timers
Bit shifters
Data types
Binary code
Sequencing
Digital inputs & outputs
Analog inputs & outputs
Scaling
Subroutines
And you will construct PLC programs to control stuff like:
Pump stages
Tank levels
Filling lines
Traffic lights
Room temperatures
The course starts off at a beginner level, we will firstly download the software and take a look at our very first PLC program, the early stages of the course will teach you about what ladder logic is and how it works in conjunction with PLC scan cycles.
After we have learnt the basics we will start to develop more complex programs. Each chapter will introduce new concepts and functions that we will use to make programs for things like tank levels and timed motor outputs.
Once we really start to get cooking we will build and simulate programs to control the traffic lights of an intersection and the temperature of chocolate in a tank. mmmmmmm!
By the end of the course your ladder logic knowledge will be solid and you will be able to write your own PLC programs from scratch.
So if you want to learn PLC programming without needing any special hardware then this is the course for you.
