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 end of the example, methods from the PLC Manager RSC service are called from an OPC UA client.

Head over to Github, and give it a try: https://github.com/PLCnext/CppExamples/tree/master/Examples/OpcPlcManager

This tutorial shows how to create a simple "Hello World" console application for a PLCnext Control device. The application is written in C# and targets .NET Core.

Note that this tutorial is intended for C# applications that run entirely outside the PLCnext Runtime. For C# applications that target the eCLR, please refer to the relevant section of the PLCnext Info Center.

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 what if, for some reason you don't want to write code? Maybe it's your first project, or maybe it's been a while? In this blog I'll show how to build a IOT Web application, without writing a single line of code!
