UriFormatException

OpcServerBase(OpcServerType, Uri)

C#

protected OpcServerBase(OpcServerType type, Uri address)

Parameters

type OpcServerType

address Uri

Exceptions

The address format / scheme can not be used as a server address.

public event EventHandler Started

Starting

C#

public event EventHandler Starting

StateChanged

Occurs when ever the State property has been changed to a different value.

public event EventHandler<OpcServerStateChangedEventArgs> StateChanged

Stopped

C#

public event EventHandler Stopped

Stopping

C#

public event EventHandler Stopping

Address

Gets or sets the (first) base address of the server.

C#

public Uri Address { get; set; }

Property Value

Uri

The first Uri used by the server to listen and response to OPC UA requests or a null reference (Nothing in Visual Basic) in case there is no base address defined.

Exceptions

The address format / scheme can not be used as a server address.

OpcApplicationConfiguration

The value is a null reference (Nothing in Visual Basic).

Addresses

Gets a read-only collection of Uri instances representing the base addresses used by the server.

C#

public ReadOnlyCollection<Uri> Addresses { get; }

Property Value

ReadOnlyCollection<Uri>

A ReadOnlyCollection´1 of Uri instances used by the server to listen and response to OPC UA requests.

Remarks

To manage the different base addresses used use the RegisterAddress(String)/RegisterAddress(Uri) method to add an additional base address or use the UnregisterAddress(String)/ UnregisterAddress(Uri) method to remove a base address.

Binding

Gets the OpcServerBinding instance used to maintain the different binding options used by the server application.

C#

public OpcServerBinding Binding { get; }

Property Value

OpcServerBinding

An instance of the OpcServerBinding class used by the OpcServer to setup and maintain the different binding options.

Configuration

Gets or sets an instance of the OpcApplicationConfiguration class which is used as a low-level representation of the code/file based server application configuration.

C#

[CLSCompliant(false)]
public override OpcApplicationConfiguration Configuration { get; set; }

Property Value

An instance of the OpcApplicationConfiguration class configured with the server specific setup to use. An assignment of a null reference (Nothing in Visual Basic) will lead to the creation of a new instance of the OpcApplicationConfiguration class with all defaults typically used by server applications.

Remarks

A file based OpcApplicationConfiguration needs to be loaded manually either using a specific config-section in its App.config (see LoadServerConfig(String)) or using a custom file using LoadServerConfigFile(String). A low-level code based server configuration can be directly performed using an instance of the OpcApplicationConfiguration like the instance provided by this property. In case there is a different instance applied to this property the property will ensure that the Address property will represent the first base address configured in the base addresses of the passed configuration instance.

Name

C#

public string Name { get; set; }

Property Value

String

Namespaces

Gets a read-only collection of namespaces used by the server.

C#

public override OpcReadOnlyNamespaceCollection Namespaces { get; }

Property Value

OpcReadOnlyNamespaceCollection

An instance of the OpcReadOnlyNamespaceCollection class with OpcNamespace items for each 'NamespaceUri' used by the server to organize the nodes in its address space.

Remarks

The items in the OpcReadOnlyNamespaceCollection provided are created during the startup of the server.

State

Gets a value that indicates the current state of the server.

C#

public OpcServerState State { get; }

Property Value

OpcServerState

One of the members defined by the OpcServerState enumeration. Which specifies the current state of the server.

CreateConfiguration()

C#

[CLSCompliant(false)]
protected virtual OpcApplicationConfiguration CreateConfiguration()

Returns

OpcApplicationConfiguration

CreateSecurity()

Creates a new instance of the OpcServerSecurity class.

C#

protected override sealed OpcServerSecurity CreateSecurity()

Returns

OpcServerSecurity

A new instance of theOpcServerSecurity class.

CreateTransport()

Creates a new instance of the OpcTransport class.

C#

protected override sealed OpcTransport CreateTransport()

Returns

OpcTransport

A new instance of theOpcTransport class.

DenyIfNotStarted()

Verifies whether the server is in started state.

C#

protected void DenyIfNotStarted()

Exceptions

The State is not equals Started.

Dispose(Boolean)

Releases the unmanaged resources used by the OpcServerBase and optionally releases the managed resources.

C#

protected override void Dispose(bool disposing)

Parameters

disposing Boolean

The value true to release both managed and unmanaged resources; otherwise the value false to release only unmanaged resources.

GetInfo()

C#

public OpcServerInfo GetInfo()

Returns

OpcServerInfo

GetInfoCore()

C#

protected virtual OpcServerInfo GetInfoCore()

Returns

OpcServerInfo

OnStarted(EventArgs)

C#

protected virtual void OnStarted(EventArgs e)

Parameters

e EventArgs

OnStarting(EventArgs)

C#

protected virtual void OnStarting(EventArgs e)

Parameters

e EventArgs

OnStateChanged(OpcServerStateChangedEventArgs)

RegisterAddress(String)

Registers the address specified as one of the base addresses used by the server.

C#

public void RegisterAddress(string address)

Parameters

address String

The uniform resource identifier which defines the communication schema, the host, the port and optionally the path to listen to.

Exceptions

The address is a null reference (Nothing in Visual Basic).

The address is an empty string or the address format / scheme can not be used as a server address.

FormatException

The address is not a valid URI format.

Remarks

In case there the address is already in use as a base address, it will not be added to the list of base addresses a second time. In case there the Address properties is a null reference (Nothing in Visual Basic), the address will be used.

RegisterAddress(Uri)

Registers the address specified as one of the base addresses used by the server.

C#

public void RegisterAddress(Uri address)

Parameters

address Uri

The Uri which defines the communication schema, the host, the port and optionally the path to listen to.

Exceptions

The address format / scheme can not be used as a server address.
