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    • How to install OPC DA library  
The OPC Server/Simulator : watch this video    • How to install Graybox OPC (DA) Simul...  
other OPC Client application for comparation : watch this video    • OPC Agent Expert : OPC DA & UA Client...  

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!
