Live Binding is supported to OPC data points, i.e. identified values (items, nodes) that are changing over time. Live Binding is currently not available for other types of OPC data, such as OPC alarms, events or conditions.
Do not confuse the live binding model with live mapping, also provided by QuickOPC. The main differences between the two are that
Following resources will help you get started with Live Binding:
In runtime, all user interface features (such as controls, dialogs, and live binding; Windows Forms and WPF) and non-visual components are supported both under .NET Framework and .NET 6+. However, "designing" them (this includes tasks like dragging from the Toolbox, or configuring in Properties window) in Visual Studio is only possible in .NET Framework projects. In order to achieve visual design for .NET 6+ projects, the developer can make two project files over the same set of source files, one targeting .NET Framework and one targeting .NET 6+, and use the project that targets .NET Framework for visual design tasks. |
WPF design-time features are not available in QuickOPC version 2024.2. This affects the ability to use Visual Studio to configure Live Binding in WPF applications, and to configure properties of QuickOPC WPF controls. You can still use XAML editing to configure properties of QuickOPC WPF controls. QuickOPC version 2024.2 still fully supports WPF in run-time, i.e. the functionality of QuickOPC WPF controls in run-time is not affected, and also existing applications that use WPF Live Binding run correctly. We are evaluating the feasibility of supporting the WPF design-time features in a future version. |
