In an earlier blog post, you learned how to pass data between an OPC UA client and a PLCnext Engineer Function Block instance, using OPC UA methods. In this example, OPC UA methods are implemented in an ACF component written in C++, rather than in a PLCnext Engineer function block. At the… Read More
The PLCnext controllers supports multiple ways of connecting to a cloud service. You could use IEC Function blocks from the IOT library, build your own .NET application, write a python script or compile a connector in GoLang. If you want to write code, you have a lot of options. But… Read More
Most automation engineers are aware that OPC UA clients can exchange data with PLCs via OPC UA tags. But did you know that OPC UA clients can also use methods to pass input data to, and receive output data from, Function Block instances in a PLC? If you would like to know… Read More
A standard in IT for years, it has not yet made much of an impact in industry. Often such technologies are seen astoo complex and unnecessary. The question that arises is, do they bring us advantages? A vision for PLCnext using the example of Kubernetes. Kubernetes Kubernete is an orchestrator… Read More
Challenge For a faster development we want to create ARM based containers for the AXCF2152 or AXCF1152 on x86 hardware. For this purpose, a virtual machine based on Debian or Ubuntu is used, which runs on our normal PC. We need a emulator To run ARM binary code on an x86 system we… Read More
Systems quickly become very large when you ship it complete. This includes the build and often the build and test environment. Even if the extraction of the files to be shipped is not a problem, it is time consuming. Containers offer the possibility to do this automatically. Here you have… Read More
This little demo project shows how to easily use a PLCnext controller as a smart home device in the open-source home automation software Home Assistant via the REST API and Modbus TCP. With the PLCnext controller you can use the Axioline components in your automation to add easily more powerful Outputs then the GPIO Pins of the Raspberry Pi, temperature sensors like Pt100 and bus systems like DALI. All you need is a working Home… Read More
By now everyone has heard about Machine Learning and how it will change everything. But very few have an idea how to start to change everything. I hope that when you try the steps in this blog, or even read about it will help you understand how to get started… Read More
