  1. What’s New In OPC Data.NET 5.1x? Renee Sikes Applications Engineer

  2. Introducing OPC A&E Custom Client Development Agenda – 45 Minutes • OPC to Visual Studio.NET Overview • OPCData.NET Overview • What’s new in version 5.11 • Live training • Set up TOP Server A&E Plug-in • Connecting to A&E server • Browsing for data in A&E server • Subscribing to A&E server • 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 32 and 64 bit .NET component • Visual Studio 2005, 2008, 2010 • Easy to use API • Abstracts much of the OPC work under the hood • Supports OPC DA and A&E • Includes UA COM wrapper • Multi-threaded, non-blocking design for high performance • Self-optimizing • OPC Self-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 • Thin-client web applications • Building your own web service or Windows Services Your OPC-DA or A&E Server Your OPC-DA or A&E Server

  8. OPCData.NET API • Two main assemblies • EasyOpcClassicNet.dll • Classes that hold common OPC information • Classes that work with OPC Data Access and OPC Alarms and Events • EasyOpcNetForms.dll • Classes that work with OPC-DA from Windows Forms applications (browsing dialogs) • SwtbExtenderReplacement.dll • Targeted for current users of SWTB Extender.NET

  9. OPCData.NET API • EasyDAClient is the main object that allows access to OPC DA servers • EasyAEClient is the main object that allows access to OPC A&E 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. What is OPC A&E? • A set of standardized interfaces used to pass alarm and event information • “alarm” and “event” used interchangeably • Designed to compliment existing OPC DA interfaces

  11. Parts of an A&E Server • Area- a logical grouping of plant equipment for which events and conditions are available • An organizational “folder” • Condition- a names state of the event server which of interest to the client • Single state • Multi-state: has mutually exclusive sub-conditions • Has a set of attributes that can be accessed to give more information to the client about the condition • Active, ActiveSubCondition, Enabled, Acked, LastAckTime, etc • Has a quality associated with it

  12. Parts of an A&E Server • Subcondition- part of a range of values which define a condition (ex. HighHighAlarm or LevelAlarm) • Has attributes associated with it including: name, definition, severity, description • Severity is spread over a range of 1 -1000, typically in an even and logical distribution

  13. Parts of an A&E server • Event- detectable occurrence in the event server • Condition-related: associated with conditions • Tracking-related: interaction of OPC client with an object in event server • Simple: any other than above • Event Categories- groupings of events support by an event server. • Includes events of one type of category (ex. Deviation alarms, level alarms, runtime error events, etc)

  14. Live Demo • Set up the TOP Server A&E Plug-in • VB.NET Client using Data.NET 5.11 • Connecting to A&E server • Browsing for data in A&E server • Subscribing to events in A&E server

  15. 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 • Multiple developer discounts available • 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
