Winforms Development

Whether you are using VB.NET, C#, Visual Basic, C++, Delphi or any of the other countless development languages, the OPC Web Client has you covered.

You can create rich Winform OPC Client applications with the following capabilities:

• Browsing
• Computers on the network
• OPC Servers available on a local/remote computer
• OPC Items (Tags) within a local/remote OPC Server.
• Retrieve the properties of the OPC Server and OPC Items.
• Subscriptions
• Subscribe and unsubscribe to one or multiple items (Tags)
• Control active status of each tag
• Reads
• one or multiple items
• synchronously or asynchronously from the OPC Servers Cache or from the Device
• Writes
• to one or multiple items
• synchronously or asynchronously to the OPC Servers Cache or Device

Multithreaded applications can benefit from using the OPC Web Client in multiple threads to assure maximum data throughput.

Which components can I use?

• .NET (VB.NET, C#) = OPCData.NET and/or OPC Web Service
• Visual Basic = OPCData.NET
• Delphi = OPCData.NET and/or OPC Web Service
• C++ = OPCData.NET and/or OPC Web Service

NOTE: If you plan on using a different development environment than what is listed above, it is still very likely that you can use the OPCData.NET components.

Be sure to contact us if you have any questions.

How do I deploy what I have made?

Depending on which component you use (OPCData.NET or OPC Web Service) will determine how you deploy your application. The OPC Web Service would be installed on a centralized server computer. If using the OPCData.NET components, then you will need to deploy them along with your application.

Where can I download example source-code?

We have a lot of example downloads and code-snippets available here.
