NOTE: This post is about TwinCAT build 4026 installed using the TwinCAT Package Manger. If you want to use usermode runtime on 4024, see my older blog post: Running TwinCAT 3 projects locally with Usermode Runtime.

I finally decided to migrate to TwinCAT 4026 on my own Thinkpad. I have very bad experience from day job about this process.

In 2015, I bought a cheap Chinese Android / Windows tablet Onda v820w. It had Windows 8.1 and Android 4 installed (Dual-OS). I thought that it could be useful at university (really wasn’t) and it didn’t cost much (~99 euros).

I have my own ESP8266-based solution that handles for example

I have always disliked the feature of the TwinCAT 3 that you need to run it in your development PC kernel level, just like on a real PLC hardware. Other systems, such as TwinCAT 2, Codesys 2 and Codesys 3, run the PLC software in separate soft-PLC application on Windows.

I have been working with TwinCAT 3 communication using Javascript, Typescript and C#.

I have been using IEC 61131-3 function block FB_init methods quite a lot for different library blocks. They allow almost constructor-like initialization possibilities for function blocks. For example it’s quite useful to pass buffer size to a block using FB_init and then initialize a dynamic array using __NEW operator.

Jo jonkin aikaa on nurkissa lojunut vanhoja VHS-kotivideoita odottaen siirtämistä digitaaliseen muotoon. Nauhat eivät meinaa kestää aikaa ja lisäksi VHS-laitteet alkavat olla jo vähän harvinaisempia. Onneksi nauhuri löytyi vielä nurkista.

I have been using Nodemailer for a few personal and commercial projects to send email from Node.js

TwinCAT has its own system logger running in ADS port 100. It logs different system messages for displaying in Visual Studio, Windows event list or in a MessageBox popup.

Hankin Burrel S12 HD+SMS III -riistakameran mökille valvontakamerakäyttöön. Kyseistä mallia oli kehuttu kohtalaisen paljon, joten ajattelin sen hoitavan homman mallikkaasti. Saas nähdä…

Due to recent development of codesys-client Node.js library, I had a need to simplify process to crete network variable list (NVL) declaration files (.GVL).

Ostettiin tuossa mökin keittiöpäivityksen yhteydessä IKEAn upotettava kaasuliesi kaasupullolla käytettäväksi.

TwinCAT local AmsNetId can be changed using Router->Change AmsNetId from tray icon menu.

In one project I have been working with ifm CR0452 R360/BasicDisplay XL HMI screen. It’s quite nice small, and not too costly, HMI for mobile machines and it can be programmed using CODESYS 2.

I have been working on an ESP8266 project lately. The idea is to create a system that reads temperature/other sensors and then sends the data using MQTT or REST. The system is fully configurable with a web browser. I’m not too good with C++ so.. not too easy :D

Haven’t developed with PHP for a while but now I got a need to do some updates to an older project. The project is based on PHP, MYSQL and HTML (+ jquery) and it also uses TCPDF library for generating PDF files.

Added possibility to add comments to posts using GitHub issues and quite cool https://utteranc.es/

This is the first post in my Github page. Let’s see how it goes.
