Description
In industry, the PLC is the most important automation device because of its role as the brain in running industrial processes. This brain uses syntax to be able to perform tasks in an orderly, sequential manner.
The native language of the PLC is called “ladder logic”. Ladder logic is graphical, in that it can be laid out in a form that resembles a ladder with rails and rungs. Ladder logic diagrams were developed originally from relay-circuit diagrams that were used for electronic circuitry prior to the advent of PLCs.
PLC Ladder Simulator is a simulator for the Android operating system with input and output objects that simulate the I/O ports of a real PLC. You can use PLC Ladder Simulator to create ladder-logic diagrams using components from the standard set used in these diagrams.
PLC Ladder Simulator PRO features a unique option available in the world and it's the possibility to program an Arduino board with a ladder design using an Android phone. So actually what it does is that transforms an Arduino into a PLC (Programmable Logic Controller). The app writes a code into the Arduino by using a USB OTG cable, a Bluetooth module or an Ethernet shield.
The Arduino mode it's compatible with the Arduino UNO (atmega328), MEGA (atmega2560), NANO (atmega328), DUE, Pro Mini, M5Stack ESP32, MH-ET LIVE ESP32 DevKit, and NodeMCU V3 LUA ESP8266.
The Pro version features compared with the Free version are:
- Arduino Mega board is available in Arduino mode. - Arduino Nano board available in Arduino mode. - Export .PLC file for the PC PLC Loader tool. - ROL ladder function. - ROR ladder function. - SCL ladder function. - No restriction for counters. - No restriction for timers. - 10 save slots to keep more designs with slot name customization.
Tutorial on how to use the Arduino mode can be found at http://plcladdersimulator.weebly.com/pro-edition.html
IMPORTANT 1: No refunds will be made after past 72 hours after the purchase of the app if the reason is to have issues with the Arduino mode, for example having issues programming the Arduino board using the app, this due the user can download the free version of the app and test it to see if the Arduino board and the Android device of the user are compatible with the app.
IMPORTANT 2: Before you buy this version you can try the FREE version to ensure that your device is compatible. -> PLC Ladder Simulator: https://play.google.com/store/apps/details?id=com.casdata.plcladdersimulator
Recent changes: Fixed Bluetooth issue on devices with Android 12 and greater.

Good app.... But need some improvement. Please add pwm instructions for servo and stepper motor running. After that good app as comparison to other apps I used ever.

It's the best ladder simulator. I also downloaded ladder simulator 2 where I learned the basics of programming.

Sergio comes through. I had an issue with the app which rendered it totally useless. I emailed him, he fixed, now all seems to be good. Give the guy a chance to get things ironed out. This app has a lot of potential and Sergio seems to be dedicated to making it work for all of us..... Thanks bro 😎.... Much appreciated

Great app. Not too hard to use as long as you know about plc programming.
The guy who wrote this is very smart, and he is quick to answer questions. I
know I will be using this app a lot. Awesome !!

Dear sir, I did one plc program simulation in above software, and I tried to upload program in Arduino board but couldn't completed by me, so now I need your help how to download the program and how execute the program I wait you valuable reply

Makes it harder than it needs to I'm currently taking a PLC class, and I got this app to experiment with a few logic programs. After fighting it for nearly 30 minutes I've finally given up. This app makes placing, editing, and addressing everything nearly impossible.

Having big time trouble loading to the arduino. From usb and PC. I wish there was a slower version on YouTube. What do you get out of it to do video's superfast? I like the program, but it's no good if you can't use it.

I want my 2f in $ back it just freezes I have an octa core and 3gRam on my Droid running Marshmallow. Freezes. I want a REFUN......

I can't see what I insert I am adding switches.subrungs etc and nothing is appeare I just see a gray screen

The UI of tye app makes it unusable. It's a total pain to use. If you want to create even the simplest program it's painstaking. To do something complex would be a nightmare. Don't waste your time. There are free apps 10x better.
