Developing an OPC Client Application with VB.Net

Hello,

I am actually working on my final year project as an electrical engineer and I need to develop an OPC Client Application with VB.Net as one of the tasks of my project.

The OPC Client Application has to be able to connect to DeltaV Operate as an OPC Server and then define groups and items so that I can manipulate them. 

Can you please help me develop such an application because I am not so familiar with OPC Standards and DeltaV Control System ?

I appreciate your efforts and your time. 
Thank you.

  Hi
  I think you should try www.matrikonopc.com . They maka a lot of OPC Servers. To my knowledge they also have OPC Development Toolkits for Servers and Clients. With these toolkits you can cocentrate on the Client Application and the OPC part will be done for you.
  there is another compagny doing similar things called softing.
  More info you can also find on the https://opcfoundation.org/products
  good luck Herby

  A number of years ago, I took a class offered by Emerson Educational Services called DeltaV OPC Client Development (7040 I believe). I don't think this course is offered any longer, but maybe by contacting Educational Services, you may get a different answer.
  
  If you look in Books on line for the article 'Barcode Tutorial', you will see a short tutorial for how to build a VB client (pre .NET) to talk to the OPC DA (Classic) server.

  I'm looking around for anything perhaps a little more up to date; I'll let you know what I find.

  I have contacted the educational services but they didn't propose a free course.
  
  I will take a look at the tutorial and let you know if I have any other difficulties.
  
  Appreciate your time and your help.

  Based on our discussion on LinkedIn, I'm going to assume it is due to licensing. Test connectivity using OPCWatchit; it will probably allow you to connect to the server but not add groups or items. I believe that is when OPCWatchit will generate an error (c004080c) .
