# OpenPLC Walkthrough

In this article, I’ll show you:

* What is OpenPLC really?
* Why virtual PLCs matter?
* How can you deploy it?
* Where does it fit in modern edge architectures?
* And how can you test it with a digital twin?

In this video, I demonstrate:

* Installing and running OpenPLC
* Programming a simple logic
* Deploying it on an edge environment
* Connecting it to a simulation

## What is OpenPLC?

**OpenPLC** is an open-source IEC 61131-3 PLC runtime.

It allows you to:

* Program in Ladder, Structured Text (ST), and FBD
* Run on Linux, Raspberry Pi, or industrial PCs
* Deploy inside Docker containers
* Communicate via Modbus, OPC UA, MQTT
* Integrate with edge and cloud systems

> In simple words: OpenPLC = A real PLC runtime running on standard hardware.

***

## Why Virtual PLCs Matter

Traditional PLC setup:

* PLC CPU, IO modules, Wiring, Power supply
* Hardware cost

Virtual PLC setup:

* Edge device with OpenPLC runtime
* Software-based IO
* Cloud Orchestration

This enables:

* Remote development and Safe testing
* Scalable training labs with Faster prototyping
* Lower cost entry into automation

> For educators and engineers, this is powerful.

***

## Where Can You Run OpenPLC?

OpenPLC is extremely flexible.

You can deploy it on:

* Raspberry Pi, Industrial PCs
* Docker containers
* Edge gateways
* Linux-based embedded systems

> This makes it ideal for IIoT prototyping, Remote labs, and educational institutions and Edge-to-cloud architectures

## Testing Your PLC Logic Without Real Hardware

Now comes the important question: How do you test PLC logic if you don’t have physical IO? You use a digital twin. And this is where **Simumatik** becomes extremely powerful.

## Simulate Machines with Simumatik

**Simumatik** is a browser-based industrial simulation platform. It allows you to:

* Build machine simulations
* Connect directly to OpenPLC
* Simulate sensors and actuators
* Teach automation safely
* Validate control logic in 3D environments

In this setup:

OpenPLC → Control Brain\
Simumatik → Virtual Machine

> Together you get a complete virtual automation lab.
