Previous: What’s New in QuickOPC.NET 5.04
Key changes: OPC Alarms and Events
- Added support for OPC-A&E specification (Alarms and Events Custom Interface Standard Version 1.10). This specification is covered by an entirely new object hierarchy with its starting point at EasyAEClient class.
- Added new SwtbExtenderReplacement assembly. You can drop classes from this assembly into your application to replace the Software Toolbox Extender (http://www.opcextender.net) component.
- New OpcAlarmsAndEvents10 property in ServerCategories object.
- Added EasyDAClient.MultipleItemsChanged event. This event is capable of passing multiple item changes in one notification, improving the performance.
- Explicit item subscriptions now honor the requested update rate precisely (without attempting to merge the neighboring rates into “buckets”). This behavior can be controlled by new EasyDATopicParameters.ExactManualGroupMatch property.
- Minor members renaming took place to better capture the meaning (e.g. EasyDAClientParameters.TopicRequestQueueSize is now RequestQueueSize, and similarly EasyDAClientParameters.TopicResponseQueueSize became simply ResponseQueueSize).
- Some numeric error codes have changed (and have been added) to accommodate OPC Alarms and Events.
- To facilitate the addition of OPC Alarms and Events support, some physical elements (such as assemblies and applications) have been renamed: EasyOpcDANet assembly becomes EasyOpcClassicNet, EasyOpcDANetForms assembly becomes EasyOpcNetForms, and EasyOpcDANetDemo application becomes EasyOpcNetDemo. Note that no logical elements (such as namespaces or classes) have been renamed for this reason.
- Associated QuickOPC.NET Bonus Pack 5.10 has been created. A new project (CSharpDocExamples1) contains examples illustrating use of individual members from the reference documentation.
