About

Hi!

My name is Jakob Sagatowski and I work as a software engineer at the European Southern Observatory. I’ve been working on various projects with embedded platforms for quite some time, and one day I discovered the world of PLC-programming, more specifically PLC-programming in TwinCAT. Unfortunately, with TwinCAT I’ve noticed that it can be quite tough to find information/examples for various problems in this development environment. As someone who is used to development in the standard embedded languages (C/C++/Ada), there is quite a road to walk when entering the world of TwinCAT and PLCs. Words as EtherCAT, TON, bExecute and Structured text are a few new users pretty quickly come across. Going from programming in Ada/C/C++ to 61131-3/ST had its differences! Still, with a PC-based PLC it was possible to do much of everything I was used to from other projects. As years are passing, experience grows so I thought it would be a good idea to create a blog about TwinCAT development. So now instead of just complaining of the lack of information on Internet regarding this, I’m sharing some of the tips & tricks regarding TwinCAT! Usually you work to solve a problem for some time, problem gets solved and then you acquired new knowledge. Thought this channel would be a good place to publish that knowledge. Despite the name AllTwinCAT, I’m also publishing other things I find interesting on this blog. I guess the name AlmostAllTwinCAT or MostlyTwinCAT just wouldn’t sound as catchy!

New posts will be published here anytime in my (decreasingly amount of) spare time. I’m not in any way affiliated with Beckhoff, nor do they in any way sponsor me. I just happen to work and spend a lot of time with their products. Fact is, you don’t have to spend a single cent to learn TwinCAT as the development environment and (time-limited) runtime is free.

Enjoy!
