  1. Connecting Runtime-Free to Any OPC-DA Server with VS.NET Got a snazzy graphic mike – remove this and put it here! Your Host Today: Win Worrall Application Engineer and Developer

  2. Connecting Visual Studio.NET to OPC Data Access Servers Agenda – 45 Minutes • OPC to Visual Studio.NET Overview • OPCData.NET Overview • Live training • Basic OPC functions • Reading, Writing, Subscribing • Browsing via code and dialog • Windows application • Web application • Discussion, Questions & Answers

  3. Using Visual Studio as an OPC Client • When you configure an HMI, you configure an OPC client connection to the OPC Server. • In VS.NET you need an OPC client plug-in tool • Good Design and Planning Still Required • Systems are only as good as weakest link Visual Basic to 1 OPC Server to 1-N Devices

  4. Client ToolPlug-In Putting it to Work Server Application

  5. OPC Client Plug-In Tools • Two Types – Free & Commercial • Free Wrapper Objects • Available from OPC Foundation • Requires understanding of key OPC interfaces and working with handles & collections • Community support only – no phone or email support • Commercial Software Tools • Variety of types & languages available • Details of OPC implementation abstracted for user • User focuses on “read this”, “write that” • Phone, email support usually included • OPC Certified solutions are available

  6. OPCData.NET • 100% managed, native .NET component • Targeted to Microsoft .NET Framework 2.0 • Works with VS 2005 and higher. • Easy to use API • Abstracts much of the OPC work under the hood • Multi-threaded, non-blocking design for high performance • Self-optimizing • OPC Certified • OPCData-COM available for ActiveX users

  7. Your application with OPCData.NET Typical Usage • Can be used from within any tool based on the Microsoft .NET Framework • Thick-client .NET applications • Windows Forms or Windows Services • Thin-client web applications • Building your own web service Your OPC-DA Server Your OPC-DA Server

  8. OPCData.NET API • Three main assemblies • EasyOpcCommonNet.dll • Classes that hold common OPC information • EasyOpcDANet.dll • Classes that work with OPC Data Access • EasyOpcDANetForms.dll • Classes that work with OPC-DA from Windows Forms applications (browsing dialogs)

  9. OPCData.NET API • EasyDAClient is the main object that allows access to OPC DA servers • Browsing via dialog or code • Allows simultaneous operations • multiple threads for improved efficiency • Error handling • OPC-related errors, COM/DCOM errors, errors returned from OPC server, errors detected by OPCData.NET library • Helper properties for increased control • Synchronous and asynchronous operations, timeout and hold periods, percent deadband

  10. Live Demo • Basic OPC functions • Reading and Multi Reads • Writing and Multi Writes • Subscribing • Browsing via code and dialog • Windows application (VB.NET) • Web application (C Sharp)

  11. What Tools are Needed? • For all usage scenarios • No tag count limits • No limits on # of clients, # of servers • OPCData.NET Single PC Usage License (p/n 41283501) $595 • OPCData.NET Single Developer + Runtime Free License (p/n 41283502) $995 • OPCData.NET Additional Developers License (p/n 41283503) $395 • OPC Data Client (p/n 41283508) $1495 • OPCData.NET • OPCData-COM • Support contracts also available (20% of List Price) • Contact us for upgrade pricing from OPCWebClient 3.02
