OPC Modbus TCP Server XP

This is a simple application (commercial / not free) for reading OPC DA and Modbus TCP that can be published as a Modbus TCP Server. We designed this app for Windows XP 32-bit, so the GUI is not pretty enough, but it can run in Windows 10.

You can purchase this little application (with full sourcecode) by sending me  an email here:

Tutorial: OPC DA Client - C# WinForm

 Hello innovators!

Welcome to this tutorial on how to create an OPC DA client application. OPC (OLE for Process Control) is a widely-used industrial automation protocol that enables communication between various automation systems. In this tutorial, we will be creating a client application that can connect to an OPC DA server, read and write data.

Before we begin, you will need to have the following installed:

+ A development environment : Visual Studio 2022

+ The OPC DA Automation Wrapper Library : watch this video https://youtu.be/KNxQExjK_CQ

+ The OPC Server/Simulator : watch this video https://youtu.be/a0WNkViknoo

+ other OPC Client application for comparation : watch this video https://youtu.be/yaCpdWu4T-A

These are the steps:

00:00 - intro

00:08 - Create a New Project

08:32 - Add Reference

09:11 - Coding / Scripting

22:42 - Testing

24:33 - Compare with OPCAgentX

25:36 - Extra

That's it! With these steps, you can create a basic OPC DA client application that can read data from an OPC server and write it. From here, you can build on this foundation to create more complex and powerful client applications that can fully leverage the capabilities of the OPC protocol.

Thanks, and have a nice day!
