On this week I have a project make PLC program(ladder program) to implement in arduino UNO,
please share to me reference,etc..for supporting my project.
Thank's
Google 'Arduino ladder'. Google is your friend.
I need official program(ladder) from Arduino ?
Hi, what experience have you with programming, Arduino.
Who is this project for? School, University, Tech, College?
What information have you been given, that is the official description of your project assignment.

Did you follow the advice in Reply #1?
What happened?

Hi,Tom & Robin2
my department in manufacturing corporation have a project to building automation machine using arduino microcontroller , the programing must using ladder diagram(PLC Program).
yesterday I follow advice in reply#1,
but, my boss request to me the programing must matching with maker of arduino/program must official from arduino.
can you help me?

When you find a program that suits you, Tell them I told you OFFICIALLY that you can use it.
Hi, I think you had better investigate how OPEN systems like Arduino works, there is no official Arduino Company that everybody obeys.
The arduino is designed to encourage open ideas from programmers and developers, so apart from the physical form, the microcontroller and bootloader, the rest is up to everybody as to how they use it.
If your company is after a system that has strict rules as to how their product is used, and will endorse your application that you want to embedded in that product.
You need to go to controller manufacturers.

The only official Arduino ladder is kept at their Italian headquarters and is used when changing a light bulb.

It was also used (briefly) to upgrade the Forum software,

And I have a picture of it...
Why is it that programming must be done in ladder logic? Custormer requirements? Maintanability?
There are several paths you can go. It seems that there are programs that cross compile ladder logic into c or assembler. The other path is using you plc's programming software and translate the generated instruction list into a number of macros for LD, LDI, AND, ANI etc

AMEN !

A step (ladder) too far.
OK,Thank's for all coments..
and now start to learning (convert C++ to ladder)..
