The package 'Beckhoff.TwinCAT.Ads' contains a client implementation for the ADS Communication protocol used by .NET Core and .NET Full Framework. It includes everything to develop own .NET applications (e.g. HMI, Datalogger) to communicate with TwinCAT devices (e.g. PLC, NC or IO-devices).
The Root object is the TwinCAT.Ads.AdsClient to communicate to all variants of local and remote ADS servers and devices or the AdsSession object.
The 7.X series of this package now supports TwinCAT 2.11 and upwards locally.
Because the Beckhoff.TwinCAT.Ads Version 6.X uses internal interfaces that are available only from TwinCAT 4024.10 on, an appropriate version must be installed locally. The package doesn't work with older installations. An alternativ approach for some use cases is to use the 'Beckhoff.TwinCAT.Ads.AdsRouterConsole' / 'Beckhoff.TwinCAT.TcpIpRouter' packages to establish your own router.
There are options to run AdsClient/AdsServer instances without having a full TwinCAT system installed on the host system.
For more information please have a look at: Beckhoff GitHub RouterSamples Beckhoff GitHub DockerSamples

[^1]: Requirement on the Host system. No version limitation in remote system communication. [^2]: Microsoft support for .NET6/.NET7 has ended. Therefore it is recommended to update .NET Applications to Version 8.
Migrating to the latest .NET Microsoft .NET support lifecycle
The following code instantiates an AdsClient object, connects to a target device (here the local System Service) and reads the ADS state asynchronously.
using System;
using System.Threading.Tasks;
using System.Threading;
using TwinCAT.Ads;
namespace AdsAsyncTest
{
class Program
{
static async Task Main(string[] args)
{
AdsClient myClient = new AdsClient();
try
{
// Connect to local TwinCAT System Service
myClient.Connect(AmsNetId.Local, 10000);
ResultReadDeviceState result = await myClient.ReadStateAsync(CancellationToken.None);
Console.WriteLine("State: " + result.State.AdsState);
Console.WriteLine("Press key to exit...");
Console.ReadKey();
}
catch (Exception e)
{
Console.WriteLine(e.Message.ToString());
}
finally
{
myClient.Dispose();
}
}
}
}
Please be aware, that the AdsRouteConsole doesn't provide the AmsPort 10000, due to the missing TwinCAT System Service. Therefore the AmsNetId of the connection must be changed to a registered remote system.
The actual version of the documentation is available in the Beckhoff Infosys. Beckhoff Information System
There are a few breaking changes in the new version to enable asynchronous programming, reducing the memory footprint and enhancement of the performance.
More details can be read in the documentation under: HowTo Samples --> Upgrading existing ADS Application code (Version 4.X --> 5.X)

### 7.0.165
Change: TwinCAT.TypeSystem.IEnumValue.Primitive renamed to IEnumValue.Value to represent the Primitive value of the enum member (old property remains marked as obsolete).
Change: TwinCAT.TypeSystem.IEnumValue.ManagedBaseType renamed to IEnumValue.BaseType to represent the managed base type of the enum member (old property remains marked as obsolete).
Fix: Error "Object must implement IConvertible" on symbolic reading of PLC Enum types via IValueSymbol.ReadValue().
### 7.0.156
Enh: Removing inefficient lock from AdsClient.IsConnected property (changing to volatile field), synchronization of Connect/Disconnect methods by SlimSemaphore instead of lock, #286141
### 7.0.152

### 7.0.86
Enh: Several new AdsClient, AdsConnection overloads that take the instancePath string as parameter to Access 'ValueByName'
Enh: Better performance with AdsClient.Disconnect / AdsClient.Dispose methods, #270737
### 7.0.79
Fix: AdsClient doesn't remove the Variable Handle from HandleCache when calling TryDeleteDeviceNotification, DeleteDeviceNotificationAsync, #269484
### 7.0.74
Fix: Race condition in SymbolCache and HandleCache accessing handles from seperate Threads, [#76](https://github.com/Beckhoff/TF6000_ADS_DOTNET_V5_Samples/issues/76)
### 7.0.60
Fix: Use Encoding.Unicode for marshalling RpcInvoke return values of type WSTRING.
Fix: WString marshalling of DynamicSymbol.TrySetMemberValue
### 7.0.36
Breaking Change: Removes .NET6 as Dependency (out-of-support)
### 7.0.25
Fix: Cannot access symbol that is an alias type to a jagged array, fixes #197676, #171438
### 7.0.10
Fix: Fixes to write ReferenceTypes via IValueSymbol.WriteValue() or IValueSymbol.WriteValueAsync(), #256269
### 7.0
Enh: Using ValueAccessMode.IntancePath for IValueSymbol.ReadValue() / IValueSymbol.WriteValue() instead of 3 roundtrips via ADS handles.
Enh: Supports **locally** installed TwinCAT 2 (via PInvoke channel)
Fallback usage of 'TcAmsServer.dll' internally enables function on systems that don't have TCP Loopback port open (e.g TC2 and systems with TCP Loopback disabled), #230847
Enh: Supports internal communication via UnixSockets, TCP/IP Loopback and PInvoke
Enh: TargetFramework dependencies changed to net8.0, net6.0, netstandard2.0
