## What is PLC Simulator, PLC Trainer?

This app is designed to help anyone that is new to PLCs and wants to learn the basics of "How a PLC works" and PLAY with a simple simulator to experiment with some simple programming. The app consist of three main sections, "How a PLC works", "PLC Block Diagram" and the PLC Simulator. The PLC Simulator allows the beginner to learn simple programming skills with 3 timers, 2 counters, 6 compare instructions, 2 Binary outputs and 3 RES outputs.  The user interface is very friendly.  For first time users, there is an information icon that shows just how easy this app is to program. 

The NEW SAVE feature allows a user to start a program and come back to it at a later time.

This app also helps people better understand the exam-off instruction -[/]-, the "Seal-In" or "Latching" logic, such as a motor start/stop circuit and much more.

Enjoy the fast growing world of PLCs.  

My daughter found it very useful for her Mechatronics class.

Try it, you will like it.

### 5/5 — Great app

*2026-08-10, version 4.4*

Thank you for putting out a nice app for PLC newbies. It’s great to see someone spend the time to plan out, design, and build this sim to let anyone have it for free and no ads! That first review from 7 years ago was just some retired PLC tech that never reached their goals in this world.  I would love to know how to make apps and do some free sims on electronics and programming myself. Thank you again for the sim!

### 5/5 — Exactly what it says on the tin

*2025-11-05, version 4.4*

I downloaded this to play around with because I needed a simple example to show people how ladder works, now I recommend it to anyone who is interested in PLCs. Great little app, thanks for building and sharing it!

### 5/5 — Great intro to PLC world

*2025-10-05, version 4.4*

Some basic info to explain what we are looking at and a  really nice SIM section to do few (9) basic assignments. Solutions are provided for comparison. Great way to get introduced to ladder logic. Would like to see a section that explains how the particular components work. Thank you for making this!!!

### 5/5 — Helps my students

*2025-06-08, version 4.4*

I been using this app to help my students understand better when their at home .

### 4/5 — Great for PLC beginners

*2024-03-08, version 4.1*

Very nice app for beginners. The UI can be more interactive but the contents are great.

### 3/5 — Not useful for what I need

*2024-01-14, version 4.1*

I was looking for something I could use for a class that is compatible with my MacBook but this app is flawed. It doesn't really do what I need it to do first off, which is whatever. Secondly, its really glitchy and totally goes cold after a little bit and I can't tell what i'm doing wrong. I gave it a couple stars because I do like the witnessing piece, when you click the cross...what a cool way to reach people to let them know about the savior of us all and that we are forgiven and loved.

### 5/5 — PLC trainer sun

*2023-05-13, version 3.1*

Make it for Google play store also Godbless

### 5/5 — Practica para empezar

*2022-12-13, version 3.1*

Buena aplicación, para empezar si no tienes conocimientos previos y quieres empezar a asimilar conceptos.

### 1/5 — This isn’t an app

*2022-08-31, version 3.1*

This “app” is basically just 3 pages with information on them.

### 5/5 — Excelente

*2022-01-23, version 3.1*

Me encanto unos de los mejores simuladores súper bien expiada 👍🏻y un solo detalle muy pequeño que tenga traducido español
