To get familiar with writing C++ code in TwinCAT, I’m going to port a satellite tracking algorithm that can calculate the position of the international space station to TwinCAT, and let it run on t...

Let’s discover the world of C++ programming in TwinCAT. Normally a PLC is programmed in any of the 5 languages defined in IEC 61131-3. It is also an option to write code in C++ or Matlab in TwinCAT...

In the last part of this blog series, we use our linked list in basic application and test the performance of the extra overhead. All the code from this blog series can be found here. Part 1 - I...

In part 1, we talked about how to implement a general node that can be used as a link in a linked list. This part is going to be about the master node who controls the full list. Part 1 - Intro ...
