Create Simple OPC DA client as .NET DLL

17 Jan 2022 15:39 #10548 by support
thank you for your interest in our products.

You probably just need to reference OpcLabs.EasyOpcClassic.dll assembly. See:

and then instantiate like "var client = new EasyDAClient();" and use the API.

There are many examples in the C# and VB.NET solutions that come with product that are just simple console apps and are doing it in this way.

I hope this helps. Let me know if you need further help.

Best regards

I have used the sample .NET forms demo project EasyOpcNetDemo and it does what I want i.e. just basic read / write.
I will be using the OPC server name and tags from static variables, so no browsing etc.
The demo project declares easyDAClient1 on the form, so how do I declare without a form. I.e what references, using etc do I need to get started?
Is there another demo?
