PLCcom.Opc.Ua.Sdk 9.1.1.2

PLCcom.Opc.Ua.Sdk: A .NET SDK for OPC UA Communication

The PLCcom.Opc.Ua.Sdk is a comprehensive .NET SDK designed to facilitate seamless communication with OPC UA (Open Platform Communications Unified Architecture) servers. This SDK provides a robust set of tools and functionalities to enable developers to build robust and efficient OPC UA applications.

What PLCcom.Opc.Ua.Sdk has to offer?

The PLCcom.Opc.Ua.Sdk is a highly optimized and modern component specially developed for .NET software developers to provide a convenient access to a client-side Opc Ua interface, e.g. To read or write data. Depending on the version, the libraries are 100% .Net files. The component can be directly linked as a reference, API calls are not necessary. It is easily to use the components in 32 or 64 bit environments as well as across platforms. The internal routines are optimized for high-performance access. With the PLCcom.Opc.Ua.Sdk, you can create applications that support the most common OPC specifications.

These includes: � DataAccess (most used) � Alarm and Conditions � Historical Data � Historical Events

Included in the software package are extensive code examples and tutorials, which illustrate the easy connection of an Opc Ua server via an OPC interface to your application and can also be used in your projects. For development support, test server and client applications are included in the delivery package.

Prerequisites

To create applications with the toolkit, advanced programming skills in a .Net programming language are advantageously required with C # or Visual Basic. The following system components are also required for the operation of the PLCcom.Opc.Ua.Sdk: � Microsoft .net Framework 4.7.2 or higher � Microsoft .net 5.0 or higher � Microsoft .net 6.0 or higher � Microsoft .net 7.0 or higher � Microsoft .net 8.0 or higher � A development environment that is compatible with .net Standard 2.1 (e.g. Xamarin)

To execute the included examples you need to have � Visual Studio 2019 or higher � A code editor compatible with .net framework

Getting started

To get started with the PLCcom.Opc.Ua.Sdk, follow these steps:

1.Install the NuGet package: Install the PLCcom.Opc.Ua.Sdk NuGet package into your project. You can find it in the NuGet package manager or by searching for "PLCcom.Opc.Ua.Sdk" in the NuGet package search. 2.Import the necessary namespaces: In your C# code, import the required namespaces from the PLCcom.Opc.Ua.Sdk package. For example:

using PLCcom.Opc.Ua;
using PLCcom.Opc.Ua.Client;
using PLCcom.Opc.Ua.Client.Sdk;

3. Enter your licence key

string LicenseUserName = "<Enter your UserName here>";
string LicenseSerial = "<Enter your Serial here>";

4. Get the Endpoint

EndpointDescriptionCollection Endpoints = UaClient.GetEndpoints(new Uri("opc.tcp://localhost:51210/UA/SampleServer"), 60000);

5. Create a a SessionConfiguration with the selected endpoint and application name

SessionConfiguration sessionConfiguration = SessionConfiguration.Build("applicationname",Endpoints[0]);

4. Create an OPC UA client: Instantiate an OpcUaClient object to connect to the OPC UA server. Provide the session configuration and your license details.

UaClient client = new UaClient(LicenseUserName, LicenseSerial, sessionConfiguration);

Usage

Reading data

//Read multiple Nodes within one call 

//first create a ReadValueIdCollection and fill this with ReadValueId objects
ReadValueIdCollection nodesToRead = new ReadValueIdCollection();
ReadValueId nodeToRead = new ReadValueId();
nodeToRead.NodeId = client.GetNodeIdByPath("Objects.Data.Static.Scalar.Int16Value");
nodeToRead.AttributeId = Attributes.Value;
nodesToRead.Add(nodeToRead);

nodeToRead = new ReadValueId();
nodeToRead.NodeId = client.GetNodeIdByPath("Objects.Data.Static.Scalar.Int32Value");
nodeToRead.AttributeId = Attributes.Value;
nodesToRead.Add(nodeToRead);

nodeToRead = new ReadValueId();
nodeToRead.NodeId = client.GetNodeIdByPath("Objects.Data.Static.Scalar.Int32Value");
nodeToRead.AttributeId = Attributes.Value;
nodesToRead.Add(nodeToRead);

//reading the nodes synchronous
DataValueCollection readresults = client.Read(nodesToRead);

Writing data

 //create a WriteValueCollection and fill this with WriteValue objects
WriteValueCollection nodesToWrite = new WriteValueCollection();
WriteValue writeValue = new WriteValue();
writeValue.NodeId = client.GetNodeIdByPath("Objects.Data.Static.Scalar.Int16Value");
writeValue.Value = new DataValue((Int16)(-16));
writeValue.AttributeId = Attributes.Value;
nodesToWrite.Add(writeValue);

writeValue = new WriteValue();
writeValue.NodeId = client.GetNodeIdByPath("Objects.Data.Static.Scalar.Int32Value");
writeValue.AttributeId = Attributes.Value;
writeValue.Value = new DataValue(-3232);
nodesToWrite.Add(writeValue);

writeValue = new WriteValue();
writeValue.NodeId = client.GetNodeIdByPath("Objects.Data.Static.Scalar.Int64Value");
writeValue.AttributeId = Attributes.Value;
writeValue.Value = new DataValue((Int64)(-64646464));
nodesToWrite.Add(writeValue);

//writing the nodes synchronous
StatusCodeCollection writeResults = client.Write(nodesToWrite);

Subscribing to data changes

//create a subscription instance 
Subscription subscription = new Subscription()
subscription.PublishingInterval = 1000;
subscription.PublishingEnabled = false;
subscription.DisplayName = "mySubsription";

//register subscription events
subscription.StateChanged += Subscription_StateChanged;
subscription.PublishStatusChanged += Subscription_PublishStatusChanged;

//add new subscription to client
client.AddSubscription(subscription);

Edit subscription parameters

//enable publishing mode of subscription and set PublishingInterval
subscription.PublishingInterval = 1000;
subscription.SetPublishingMode(true);
subscription.Modify();
