Description

LadderTouch is application to learn the rudiments of Ladder Logic which is graphic program language.
This app has three functions.
You can learn the mechanism by executing some prepared samples.
You can check your understanding by questions.
In addition, an original circuit can be made and executed.
Ladder function of timer,counter, and logical inverse is provided.
UI is designed for easy operation.The line is written by tracing the screen. Tapping a cell at which you want to add element, the element selection screen is appeared.

---------------ELEMENTS---------------
input(yellow)
max 5 elements.
controll input signal by tapping button on bottom of display.

vertual output(red)
max 5 elements.

inner memory(gray)
max 20 elements.
vertual output(red) and inner memory(gray) are same at logical behavior.
but difference is in how to use.
vertual output is for last element of ladder logic chain.
inner memory is for process element of ladder logic chain.
this is imitation of real ladder logic that have output devices.

timer(blue)
max 5 elements.
set from 0.1sec to 10.0sec setting unit is 0.1sec.
timer is 'on delay' only.this app does not include 'off delay'.

This is on delay.
---++++++++++ sourse(rectangle)
-------++++++ destination(circle)

This is off delay.
+++---------- sourse
++++++++----- destination
+ON -OFF
time flows left to right

counter(green)
max 5 elements.
set form 1 to 50
there is NO counter reset element in my app.(many another ladder logic software have)
how to reset counter is to stop running Ladder.

all element can inverse on source area(rectangle elements area).
but on destination area(circle elements area),input,output and inner memory can inverse,
and timer and counter can't do,
becouse it is difficult to understand that timer and counter's inverse logic on destination area.

---------------EDIT---------------
paid version only.
write Ladder on 4(horizon) x 20(vertical) cell.

write element or line(pencil icon)
element:tap where you want set element and select element.
line:draw where you want write line.
