Description

LadderTouch is an app to learn the basics of ladder logic, which is a graphical programming language.
This app has three functions.
You can learn about that mechanism by executing some of the prepared samples.
You can check your understanding with questions.
In addition, you can create and execute your own ladder.
Ladder functions of the timer, counter, and logical inverse are provided.
The user interface is designed to be easy to operate. The lines are written by tracing the screen. You can set an element by tapping a cell at which you want to add it.

---------------ELEMENTS---------------
Input(yellow)
Up to 5 elements.
You can control the input signal by tapping the buttons at the bottom of the display.

Virtual output(red)
Up to 5 elements.

Internal memory(gray)
Up to 20 elements.
Virtual output(red) and internal memory(gray) are the same for logical behavior.
But the difference is in usage.
The virtual output is the last element in the ladder logic chain.
The Internal memory is for the processing element of the ladder logic chain.
These are an imitation of the actual ladder logic with the output devices.

Timer(blue)
Up to 5 elements.
The timer can be set from 0.1 seconds to 10.0 seconds. The setting unit is 0.1 second.
The timer works only 'on delay'. This app does not include 'off delay'.

On Delay.
---++++++++++ source
-------++++++ destination

Off Delay.
+++---------- source
++++++++----- destination

+ ON
- OFF
Time flows from left to right

Counter(green)
Up to 5 elements.
You can set from 1 to 50.
There is no counter reset element in this app. Many other ladder logic software has it.
The way to reset the counter is to stop running the ladder.

All elements can be inverse in the source area.
However, timers and counters cannot do it in the destination area.
It is difficult to understand the inverse logic of a timer and counter in the destination area.

---------------EDIT---------------
You can edit ladders only with the paid version.

How to write elements or lines
Select the pencil icon.
To add an element: Tap where you want to set the element and select the element.
To draw a line: Draw where you want to write a line.

How to delete elements or lines
Select the eraser icon.
Tap where you want to delete the element.

How to scroll
Select the scroll icon, then you can scroll.

How to remove useless spaces
Select the order icon.
Tap order icon to remove useless spaces.

Line color
Green with complete ladder logic.
Red with something wrong.

--------------Other--------------
There is no function that connects to outer devices.

What’s New

Version 2.1.0

The number of ladders that you can make has been increased from 20 to 30.
I have updated the introduction section of other apps as the number of apps has increased.

Awesome for prototyping!

I usually program AB Micro820s at work, but wanted something I could use to prototype small automation projects with while on flights, watching TV, etc. this app works great on my iPad and iPhone for that very purpose. I do wish it had 3 enhancements however. (1) Let me rename the notebooks, (2) Let me give the logical component addresses alias names, (3) I wish I could have some inputs that were momentary while others were held instead of all one way or the other. Thanks for creating his app!!!

Great for my wants and needs

I am not a PCL programmer. However I have done a fair number of projects where I used ladder logic as in motorcycle and car lighting up to plant control design of an industrial facility. I have wanted a computer based tool to allow me to design and test my logic. I found it!. This app allows design and tutoring in ladder logic. I am loving it - using it on my tablet and phone.

Great app, especially for my classes

I love using this app and playing around with it to learn more tricks with PLCs. I only wish that there was at least one more push button to allow for more possibilities.
