Dear existing & future PLC software developers, I have published the last part of my free PLC programming using TwinCAT 3 tutorial.
So we’ve come to an end. For the last two years all my weekends, holidays, summer/winter vacations and basically every free-moment I’ve had, went into the creation of the free “PLC programming using TwinCAT 3” course on YouTube. It’s been the biggest hobby-project I’ve ever commited myself to, and I together with my wife would like to finish by saying a few words.
Dear existing & future PLC software developers, I have published part 17b of my free PLC programming using TwinCAT 3 tutorial.
TDD is the practice of writing tests before writing the implementation code. Writing software using the practice of TDD is something that has been around in the traditional software development industry for a while, but only recently has gained attention in industrial automation. In this series of videos, we will look at the theory of TDD, and then see how it’s done in practice. In this episode, we will implement the code that we wrote tests for in episode 17a.

Dear existing & future PLC software developers, I have published part 16 of my free PLC programming using TwinCAT 3 tutorial.
Ever wondered what challenges you face if you want to develop PLC software for the worlds largest optical telescope? In this episode we are going to talk about the TwinCAT automation interface, which you can use if you want to automate the configuration, development and deployment process of your PLC software.
Simply stated: automate the automation!
Dear existing & future PLC software developers, I have published part 15 of my free PLC programming using TwinCAT 3 tutorial.
The Automation Device Specification (ADS) is Beckhoffs middleware to communicate with Beckhoff PLCs. It’s used for all kinds of use cases, as software deployment, reading/writing of variables and for internal communication of software modules. In this part we’ll go through the theory and also write some C# software to communicate with a PLC. We’ll also do a simple C++ program running under Linux that talks to the PLC!
The final part of the XPlanar series is out now! In this third and last part we will finish the TwinCAT 3 project we started and finally run the whole project in simulated mode.
Part 2 of the XPlanar series is out now! In this second part we will create a new TwinCAT 3 project and get introduced to the XPlanar configurator. We will also start writing the software for XPlanar.
Together with Isaac Spear from Beckhoff Automation USA I’ve created a series of three videos where we will look into XPlanar, which is Beckhoff’s planar motor system, which combines the advantages of conventional transport technologies with magnetic levitation. In this first part we will get an introduction to the system and the theory behind it. In the later videos we will do some practice.
Dear existing & future PLC software developers, I have published part 14 of my free PLC programming using TwinCAT 3 tutorial.
After working for a few months and years, you’ll will be in a situation where you have to manage several PLCs and machines, and they will all be running different versions of TwinCAT. But we’ve so far only installed one version of TwinCAT on our development machine. What if we want to work with a machine that runs an older or newer version of TwinCAT? This part will go through how this is done.

Proper version control is traditionally not done in the world of automation, which is a big shame. The question should not be whether version control should be used or not. The question should instead be what version control system should be used. In this part we will get an introduction to version control in general, and Git in particular. We will start with an introduction to some basic concepts of version control and then show you how you can put your automation projects under version control using Git, using free and open-source tools that are traditionally used in the software industry. You’ll learn how to do proper 100% free and Git-based version control using TwinCAT 3! Let’s start demanding more from our automation vendors and demand that the tooling for version control should be included by default, and get out of the dark ages!
