What's new in QuickOPC 2019.2
From OPC Labs Knowledge Base
See also: Versions; Previous version: What's new in QuickOPC 2019.1
Internal version number: 5.56
Key changes:
- OPC UA PubSub support
Technology
- For .NET Standard OPC UA, uses OPC Foundation's OPC UA .Net Standard Library 1.4.357.28.
Packaging
- For easier debugging, added NuGet symbol package for OpcLabs.QuickOpc, with PDB files for .NET Standard.
Installation and Uninstallation
- Simplified setup choices by merging together the installation components for individual tools.
Component Improvements
- OPC UA PubSub is now supported, initially with UADP message mapping and OPC UA UDP and OPC UA Ethernet transport protocol mappings.
Specialized Client Objects
- A new EasyUAPublishSubscribeClient component allows (read-only) access to OPC UA PubSub configurations, accessed either through an information model in an OPC server, or stored in a binary file.
COM
- Added missing methods: _EasyUAClient.BrowseEventSources, _EasyUAClient.BrowseNotifiers.
- Changed some arguments types (arrays, mainly) to be usable by broader set of COM tools. Most notable change (in C# syntax): 'out/ref object[]' changed to 'object'.
- Added property _ValueResult.RegularizedValue. Returns value in which arrays are always arrays of System.Object (transforms to VARIANT in COM). Regularized values are necessary for some COM tools, such as VBScript.
- Added method _UASimpleAttributeOperand.ToUAAttributeField (allows shorter code).
Component Refactorings
- Unexpected exceptions from UA SDK are now propagated (and not just logged as internal errors), making it easier to diagnose them.
Tools and Online Services
- The OPC Command-line Tool (OpcCmd) is now deployed during the installation, and a link to it (in interactive mode) added to the Start menu.
- The OPC-UA Demo Publisher (UADemoPublisher) is now deployed during the installation, and a link to it added to the Start menu.
