OPC Client Toolkit Made Right

QuickOPC can be characterized as an OPC toolkit. It has, however, some characteristics that make it different from other OPC SDKs on the market. Specifically, it does not expose the imprint of underlying OPC methods to its own API - it does not require you to deal with the low level stuff. And, it transforms the OPC communication into an API that appears to be connection-less; this allows your code be free of all setup, tear-down, and re-connection worries.

Communication beyond limits

QuickOPC is a radically new approach to access OPC data. It is an ideal tool to publish OPC data on the web or integrate OPC connectivity to custom applications involved in industrial automation or process control.

QuickOPC gives unbelievably short code to create OPC clients. In addition, using complex heuristic algorithms to optimize itself on the fly, QuickOPC toolbox provides the most efficient, fastest access to the OPC data.

OPC Labs has successfully tested QuickOPC at OPC Foundation Interoperability Workshops against a large set of OPC Servers from various vendors.

Why QuickOPC?

• It works in a wide range of programming languages and tools. C# and Visual Basic are the most obvious, but the list is very long.
• OPC Specifications: QuickOPC supports OPC Data Access 1.0, 2.0 and 3.0, OPC Alarms and Events 1.10 and earlier, OPC XML-DA 1.01, and OPC Unified Architecture (natively, or through UA COM Proxy - included).
• You can develop on Microsoft Windows in .NET, or with a use of COM-based tools. Read more about the platforms.
• You can pick from, or combine multiple development models. When developing user interfaces, you can replace or supplement the traditional imperative programming by a codeless Live Binding model. More advanced models such as Live Mapping, or Reactive Programming, are available as well.
• QuickOPC toolbox is suitable for a wide range of usage areas in process control and industrial automation. For example, developing HMIs, dynamic recipe loading, or customized data loggers, is straightforward.

Standalone Installer

This is what you get when you directly download the software from the Web site, or obtain it on a distribution media such as flash disk. The installation can then be started by running the setup program and following the on-screen instructions. The setup program presents a wizard-like series of steps, and offers "express" installation choices that allow the installation with just a few clicks, as well as "custom" installations with variety of individually selectable components.

The installation program requires that you have administrative privileges to the system. The installation package file is code-signed, increasing security, improving trust, and providing better download experience from the Web.

The Setup program has command-line switches that allow it to be run silently, and included in your own automated installation programs.

The product includes an uninstall utility and registers itself as an installed application in Windows. It can therefore be removed easily from Control Panel. Alternatively, you can also use the Uninstall icon located in the product’s group in the Start menu.

NuGet packages

NuGet (www.nuget.org) is a free and open-source package manager designed for the Microsoft development platform. The goal of NuGet is to make the process of incorporating third party libraries into your solutions as simple as possible. In addition to a standalone installer, QuickOPC, OPC Wizard and Rapid Toolkit for Sparkplug are provided in form of NuGet packages. Using NuGet allows you to simplify the management of libraries and their dependencies, with better control over library versioning and updates. You need to use a NuGet client (such as the one that comes with Visual Studio) in order to access the NuGet packages.

The NuGet client tools provide the ability to produce and consume packages. Our NuGet packages are hosted in the NuGet Gallery (https://www.nuget.org/packages). The NuGet Gallery is the central package repository used by all package authors and consumers.

When you use NuGet to install a package, it copies the library files to your solution and automatically updates your project (add references, change config files, etc.). If you remove a package from your project, NuGet reverses whatever changes it made so that no clutter is left.

Note that NuGet is primarily a tool for resolving build-time dependencies. The amount of functionality that you get through NuGet packages is smaller than what Connectivity Software can actually do for you. If you want a full coverage of the features, including all associated tools, you would be better off downloading the Setup program. Further below you will find a list of differences between the two distribution forms.

List of available NuGet packages

• OpcLabs.QuickOpc: OPC client and subscriber components for all environments and project types.
• OpcLabs.QuickOpc.Forms: Components that are specific for Windows Forms (can be partially used from WPF as well).
• OpcLabs.QuickOpc.Mqtt, OpcLabs.QuickOpc.MqttNet: MQTT communication packages (for OPC UA PubSub).
• OpcLabs.QuickOpc.Pcap: Ethernet communication package (for OPC UA PubSub).
• OpcLabs.OpcWizard. For rapid OPC UA server development.
• OpcLabs.EasySparkplug: Rapid Toolkit for Sparkplug - for host application and edge node development.

Example-only packages: For C# OpcLabs.OpcStudio.Sample.CS, for VB.NET OpcLabs.OpcStudio.Sample.VB.

What is included in the NuGet packages

• QuickOPC: Runtime assemblies for all OPC specifications and programming models.
• QuickOPC: OPC browsing dialogs and browsing controls for Windows Forms.
• OPC Wizard and Rapid Toolkit for Sparkplug: Runtime assemblies.
• IntelliSense support (XML comments).

Python packages

The Python Package Index (PyPI) is a repository of software for the Python programming language. QuickOPC Python packages are hosted on pypi.org.

Note that Python packages are primarily a tool for resolving dependencies. The amount of functionality that you get through QuickOPC Python packages is smaller than what QuickOPC can actually do for you. If you want a full coverage of the features, you should also install the full product using the the Setup program. Further below you will find a list of differences between the two distribution forms.
