Internal version number: 5.81

Key changes:


Targeting

  • .NET 7 is no longer supported (Microsoft end of support May 14, 2024), but will likely work. .NET 6 and and .NET 8 continue to be supported.
  • Windows 11 version 21H2 is no longer supported (Microsoft end of support October 10, 2023), but will likely work.

Technology

  • OPC UA Client-Server parts are now based on OPC Foundation UA-.NETStandard 1.5.373.121.

Licensing

  • The LicenseInfo property on the main components now returns the dictionary alphabetically ordered.

Installation and Uninstallation

  • The Setup wizard for QuickOPC now offers a choice of "express installation" for Python development. When selected, only the setup components relevant for Python developers are installed.
  • The .NET examples group is split into sub-groups for C#, C++/CLI, F#, PowerShell and VB.NET.

Component Improvements

OPC UA

  • Added static method UANodeId.FromUABuiltInType, and an implicit conversion operator, for conversion from UABuiltInType to a UANodeId representing the datatype Id for the built-in type.
  • Added method UANodeId.ToUABuiltInType, and an explicit conversion operator, for conversion from UANodeId representing the data type Id to UABuiltInType that corresponds to the data type.
  • Added constructors to UADataValue and UAAttributeData that allow specifying just the value and source timestamp.

OPC UA Client-Server

  • Added static property ObjectsStrict to the UABrowseParametersClass, and modified the behavior of the Objects static property. The ObjectsStrict static property now returns browse parameters according to strict interpretation of the OPC UA specification, and browses only the HasComponent references. The Objects static property uses a loose interpretation (needed for some non-compliant servers), and browses any HierarchicalReferences.
  • Added a new overload of the IEasyUAClient.Browse extension method. The overload takes an endpoint descriptor, node descriptor, node classes, and reference type id as inputs.

OPC UA PubSub

  • The "tls" scheme can now be used in resource addresses, and is equivalent to "mqtts" or "ssl".

OPC UA Administration and PKI

  • On Windows, certificate directory store paths that are too long to work normally are automatically detected and transformed to Windows extended-length paths.

Component Refactorings

  • Renamed properties in NotifyingWidget: QueueCallbacks to QueueNotifications, CallbackQueueCapacity to NotificationQueueCapacity, and CallbackQueueIdleTimeToSleep to NotificationQueueIdleTimeToSleep.

OPC UA

  • Turned UACodeBits static class (with list of integer constants) to an enumeration. Added implicit conversion operator from UACodeBits enumeration to UAServiceResult.
  • Renamed classes (generally by adding the word "Client", in order to achieve the necessary distinction from classes used in server development); corresponding COM interfaces have been renamed in the same way:
    • EasyUAAdaptableParameters to EasyUAClientAdaptableParameters.
    • EasyUAEngineParameters to EasyUAClientEngineParameters.
    • EasyUAInstanceParameters to EasyUAClientInstanceParameters.
    • EasyUASharedParameters to EasyUAClientSharedParameters.
    • UAEnhancedSessionParameters to UAEnhancedClientSessionParameters.
    • UASmartEngineParameters to UASmartClientEngineParameters.
    • UASmartSessionParameters to UASmartClientSessionParameters.

OPC UA Administration and PKI

  • The default application URI template string has changed. It now uses canonicalized host name, and "http" scheme instead or "uri". For more information, see OPC UA Application URI Derivation.

User Interface

OPC UA Administration and PKI

  • On the "Application certificate" tab in the "Administer OPC UA Application" dialog, the program now detects a mismatch between the application URI configured in the application manifest, and the application URI in the certificate (Subject URL Name). A warning is issued when the mismatch is detected, and an automatic fix (regenerating the self-signed certificate) is offered.
  • In the methods that invoke the "Administer OPC UA Application" dialog, you can now programmatically control whether the Pull Certificate Management features are allowed in the dialog (the Pull Certificate Management is typically used with OPC UA clients, but not with OPC UA servers).
  • The "Administer OPC UA Application" now allows the user to specify Host names that go into the application instance certificate (used with applications that are Servers).
  • The property grid on the "Application certificate" tab of the "Administer OPC UA Application" dialog now also has a dedicated row for the the Domain Component element of the certificate Subject Name.

Windows Forms Dialogs

  • Added LooseReferenceTypes property to the UADataDialog class. When true (the default), it causes the dialog to browse following very wide set of reference types, in order to cope with non-compliant servers.

Development Productivity

Visual Studio Integration

  • The Visual Studio extension (VSIX) has been renamed from "QuickOPC" to "OPC Studio".

Configuration and Instrumentation

OPC UA

  • There are now three separate event log sources: "OPCLabs-UAClientEngine" for events coming from the OPC UA client part of QuickOPC, "OPCLabs-UAPubSubEngine" for events comings from OPC UA PubSub part, and "OPCLabs-UAServerEngine" for event coming from the OPC UA server part of OPC Wizard (previously, single "OPCLabs-UAEngine" event source was used).

Tools and Online Services

Connectivity Explorer

  • Added two new endpoints under "Well-known" OPC UA Client-Server points: One for the standard OPC UA server endpoint on the local computer ("opc.tcp://localhost:4840"), and the other for default server endpoint of servers created with OPC Wizard ("opc.tcp://localhost:48040").

OpcCmd Utility

OPC UA Client

  • The uaClient collectSoftwareInfo command now also collects the new server capabilities introduced in OPC UA 1.05 (such as MaxSessions, MaxSubscriptions, etc.).

OPC UA Server

  • The uaServer start command starts an OPC UA server with pre-defined content (data variables without various behavior and data types under the standard Objects folder). By default, it opens its endpoint on "opc.tcp://localhost:48040/".

Examples

Platform: .NET

  • Wherever feasible, converted the C# and VB.NET example projects for Console and Windows Forms to the "SDK" (multi-target) format, allowing them to be built for and run on either .NET Framework 4.7.2+, or .NET 6+.
  • Split the example solutions to separate client development, subscriber development, and server development. Some common projects are shared between the solutions.
  • Renamed project folders, adopting a naming convention which clearly distinguishes between common, client, server, and subscriber examples (using "Common-", "Client-", "Server-", and "Subscriber-" prefix).

OPC UA Client-Server

  • Added C# example showing how to read the build information of the server.
  • Added C# example showing how to remove the own application certificate.

Documentation and Help

  • Significantly improved the reference documentation.
  • Removed integration with Visual Studio help system (Microsoft Help Viewer). Instead, links to the full Web-based reference documentation are provided from all IntelliSense topics.
