QuickOPC

  • NuGet package: OpcLabs.QuickOPC
  • Python package: opclabs_quickopc

QuickOPC is a suite of OPC Client/Subscriber Development Components for .NET, COM and Python. These components are for OPC "Classic" (COM/DCOM-based), OPC XML-DA, and OPC Unified Architecture (including OPC UA PubSub) specifications.

QuickOPC is a commercially licensed product. Without a license key, it runs in a trial mode. The trial provides valid data to client or subscriber applications for 30 minutes; after that period, the component (your app) needs to be re-started, and so on. You must also comply with licensing terms for 3rd-party material redistributed with QuickOPC. For details, see the documentation.

Remember that NuGet or Python packages are primarily a tool for resolving build-time dependencies. The amount of functionality that you get through QuickOPC NuGet or Python packages is smaller than what QuickOPC can actually do for you. If you want a full coverage of the features, you would be better off downloading the Setup program from OPC Labs Web site. Further below you will find a list of differences between the two distribution forms.

QuickOPC requires .NET Framework 4.7.2, .NET Core 3.1 or .NET 6.0 as a minimum. Under .NET Core and .NET 6.0+, it is supported on Linux, macOS and Microsoft Windows. QuickOPC can also be easily used from Python.

PLEASE DO NOT USE PRE-RELEASE PACKAGES UNLESS INSTRUCTED TO DO SO.

Knowledge Base link - Tool Downloads

  • Various tools, such as Connectivity Explorer, Launcher, OPC UA Demo Publisher, OpcCmd Utility, UA Configuration Tool.
  • License Manager (GUI or console-based) utility.

How to start

If you do not mind reading the documentation: Getting Started. Or, the whole User's Guide.

Otherwise, just instantiate one of the following objects (depending on the OPC specification), and explore its methods:

  • OpcLabs.EasyOpc.DataAccess.EasyDAClient (for OPC DA, OPC XML-DA)
  • OpcLabs.EasyOpc.AlarmsAndEvents.EasyAEClient (for OPC A&E)
  • OpcLabs.EasyOpc.UA.EasyUAClient (for OPC Unified Architecture)
  • OpcLabs.EasyOpc.UA.PubSub.EasyUASubscriber (for OPC UA PubSub)

Example code

C#:

using OpcLabs.EasyOpc.UA;
...

var client = new EasyUAClient();
object value = client.ReadValue(
    "opc.tcp://opcua.demo-this.com:51210/UA/SampleServer",
    "nsu=http://test.org/UA/Data/ ;i=10853");

Python:

import opclabs_quickopc
from OpcLabs.EasyOpc.UA import *

client = EasyUAClient()
value = IEasyUAClientExtension.ReadValue(client,
                                         UAEndpointDescriptor('opc.tcp://opcua.demo-this.com:51210/UA/SampleServer'),
                                         UANodeDescriptor('nsu=http://test.org/UA/Data/ ;i=10853'))

Examples on GitHub

Using the example packages (NuGet)

In order to run the code from console-based example packages, you need to call it from your project. The examples are organized by the OPC specification, and each example is a static method that you can directly invoke. For easier exploration, there are also methods that provide the user with a menu of methods to choose from.

For OPC Alarms&Events examples, call method: DocExamples.AlarmsAndEvents.AEExamplesMenu.Main1

For OPC Data Access examples, call method: DocExamples.DataAccess.DAExamplesMenu.Main1

For OPC XML-DA examples, call method: DocExamples.DataAccess.Xml.XmlExamplesMenu.Main1

For OPC Unified Architecture examples, call method: UADocExamples.UAExamplesMenu.Main1

For OPC UA PubSub examples, call method: UADocExamples.PubSub.PubSubExamplesMenu.Main1

Alternatively, you can call just a single selected example, e.g. for reading an OPC UA node, call the UADocExamples._EasyUAClient.Read.Main1 method.
