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?

​
Watch the Full Video First

Before reading further, I recommend watching the complete walkthrough:
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.
OpenPLC Walkthrough
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.

​
Interested in Trying Simumatik?

We are officially offering Simumatik educational licenses. If you:
  • Want to use it in your school
  • Build a training lab
  • Practice PLC programming in simulation
  • Teach automation remotely
