TwinCAT

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!

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.

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!

Dear existing & future PLC software developers, I have published part 8 of my free PLC programming using TwinCAT 3 tutorial.

As TwinCAT 3 conforms to the IEC61131-3 standard, there are certain things it has to be able to do. The Tc2_Standard library has many of the standard IEC functions such as timers and triggers, which we will look into in this part of the tutorial.

Dear existing & future PLC software developers, I have published part 7 of my free PLC programming using TwinCAT 3 tutorial.

In this part we will go back to basics of IEC 61131-3 and structured text and look into instructions. This will cover IF/ELSE, CASE-switches and FOR/WHILE-loops. We will utilize our knowledge to write a CSV (comma separate value) event logger by using a state machine.

Dear existing & future PLC software developers, I have published part 6b of my free PLC programming using TwinCAT 3 tutorial.

In this part we will continue our journey of the object oriented features of IEC 61131-3 and look into something called interfaces. Interfaces provide a layer of abstraction so that you can write code that is ignorant of unnecessary details. Interfaces aid you in designing more modular and robust software. With interfaces it’s possible to decouple direct dependencies between objects in your software.

I have reached 1000 subscribers on YouTube! I never thought I’d get anywhere close to this huge amount of subscribers, especially not this fast! Since I published the first episodes of the “PLC programming using TwinCAT 3 tutorial” in the beginning of March on YouTube, the channel has received over 30.000 views. It seems free PLC programming tutorials are appreciated. It’s time to celebrate and answer some questions that I’ve got from you viewers!
