What's new in OPC Studio 2024.2

See also: Versions; Previous version: What's new in OPC Studio 2024.1

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.

Technology

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

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.

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.

OPC UA PubSub

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

Component Refactorings

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

OPC UA

• 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.

User Interface

OPC UA Administration and PKI

• 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).

Windows Forms Dialogs

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

Tools and Online Services

OpcCmd Utility

OPC UA Client-Server

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

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+.

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.
