Key changes:



Component Improvements

OPC Alarms&Events

  • It is now possible to specify AEBrowseFilter.All in browse parameters passed to IEasyAEClient.BrowseNodes, which allows you to obtain both sources and areas in one call.

Component Refactorings

OPC Classic

  • Boxing of client-side OPC proxies/stubs is now also available in .NET Core (on Windows), not just in .NET Framework. This means that if your .NET Core application is using OPC Classic, it does not require "OPC Core Components" as a prerequisite.

OPC Alarms&Events

  • Added overloads with more combinations of parameters to IEasyAEClientExtension.SubscribeEvents, and toAEEventsSubscriptionArguments and AESubscriptionFilter constructors.

Tools and Online Services

OpcCmd Utility

  • Added aeClient command, providing access to OPC A&E functionality. Available subcommands are browseNodes, browseServers, getConditionState, subscribeEvents, queryEventCategories and querySourceConditions.
