Opc Da for .NET

This package allows you to use the OPC DA protocol in .Net applications.

NOTE: The OPC DA is only supported in Windows platforms.


You can install this package with command:

dotnet add package OpcDaNetCore


Find servers

You can find available servers by specifying the ip address:

var servers = await BrowseOpcDaServers.BrowseServersAsync("localhost");

Build a Service

You can build an OPC DA service using the selected server from previous method:

ServerHost host = servers.FirstOrDefault();
using var server = await new OpcDaFactory()

Or you can add server specifications manually:

using var server = await new OpcDaFactory()

You can browse nodes:

var browse = await server.BrowseNodeAsync(null);

foreach (var browseElement in browse)
    Console.WriteLine($"{browseElement.Name}; {browseElement.Id}; Has children: {browseElement.HasChildren}");

var node = browse.FirstOrDefault()?.Id;

browse = await server.BrowseNodeAsync(node);

foreach (var browseElement in browse)
    Console.WriteLine($"{browseElement.Name}; {browseElement.Id}; Has children: {browseElement.HasChildren}");

You can add items to a group. If the group does not exists, then will be created:

server.AddItems("Group 1", "Simulation Examples.Functions.Ramp2", "Simulation Examples.Functions.Ramp3");

You can remove items from a group:

server.RemoveItems("Group 1", "Simulation Examples.Functions.Ramp2", "Simulation Examples.Functions.Ramp3");

You can read all items in a group:

var read = server.Read("Group 1");

foreach (var readElement in read)
    Console.WriteLine($"{readElement.ItemName} - {readElement.Value}");

Or read specific items. In this method you can read any item available in the server, not just items from a specific group, but must specify a group:

var readAny = server.Read("Group 1", "Simulation Examples.Functions.Ramp1", "Simulation Examples.Functions.Sine1");

foreach (var readElement in readAny)
    Console.WriteLine($"{readElement.ItemName} - {readElement.Value}");

You can write into tags:

var valueToWrite1 = new ItemDataValue("Channel1.Device1.Tag2", 125);
var valueToWrite2 = new ItemDataValue("Channel1.Device1.Tag3", 126);
server.Write("Group 1",valueToWrite1, valueToWrite2);
