LadderTouchLite is application to learn Ladder Logic which is program language to control of machinery.
This app has two functions.You can learn the mechanism by executing some prepared samples.And you can check your understanding by questions.
Please watch the video on the support URL for detail.

differences from full version
edit mode isn't in.
less samples.

---------------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.


--------------another--------------
there is no function that connect to outer devices.
