Course

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.

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.

Dear existing & future PLC software developers, I have published part 13 of my free PLC programming using TwinCAT 3 tutorial.

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!

When installing the TwinCAT development environment and runtime you get access the core functionality, but sometimes you might want to extend this with additional functionality as for example adding an SQL database connection. In this chapter we will investigate some TwinCAT functions that can be added.

I wanted to share with you a tiny celebration and some frequently asked questions, as I’ve recently reached 5000 subscribers on my YouTube channel. I didn’t even know whether there was 5000 people that work with TwinCAT 3 on planet Earth, let alone that would be interested in a TwinCAT 3 related YouTube channel!
