PlcDeviceConnection Members

Namespace: IPS7Lnk.Advanced
Assemblies: IPS7LnkNet.Advanced.dll, IPS7LnkNet.Advanced.dll
The PlcDeviceConnection type exposes the following members.

PlcDeviceConnection(IPlcDevice)

Initializes a new instance of the PlcDeviceConnection class using the specified device.

C#

protected PlcDeviceConnection(IPlcDevice device)


Parameters

The IPlcDevice associated with the new PlcDeviceConnection.


Exceptions

ArgumentNullException

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

DefaultTimeout

Represents the default timeout value that is used by the PlcDeviceConnection as initial value of all timeout properties.

C#

public static readonly int DefaultTimeout


Field Value
Int32

Closed

Occurs when a connection transitions into the closed state.

C#

public event EventHandler Closed

Closing

Occurs when a connection transitions into the closing state.

C#

public event EventHandler Closing

Connected

Occurs when a connection transitions into the connected state.

C#

public event EventHandler Connected

Connecting

Occurs when a connection transitions into the connecting state.

C#

public event EventHandler Connecting

Disconnected

Occurs when a connection transitions into the disconnected state.

C#

public event EventHandler Disconnected

Faulted

Occurs when a connection transitions into the faulted state.

C#

public event EventHandler Faulted

Opened

Occurs when a connection transitions into the opened state.

C#

public event EventHandler Opened

Opening

Occurs when a connection transitions into the opening state.

C#

public event EventHandler Opening

StateChanged

Occurs when a connection transitions into a different state.

C#

public event EventHandler<PlcDeviceConnectionStateChangedEventArgs> StateChanged

BreakDetectionTimeout

Gets or sets the time that is used to detect a connection break.

C#

public int BreakDetectionTimeout { get; set; }


Property Value

Int32

The time in milliseconds to detect a connection break.



Exceptions

ArgumentOutOfRangeException

The value specified is less than zero.



Remarks

The default value of this property is DefaultTimeout.

Channel

Gets the channel object used to communicate with the Device.

PlcDeviceConnectionChannel

The PlcDeviceConnectionChannel used by the connection to operate on the Device this connection belongs. The PlcDeviceConnectionChannel returned can be used by one or more connections.



Remarks

Only in case there the last connection using a channel gets closed, the channel gets finally released. The shared use of channel objects takes only place in case there the UsePool property is set to the value true before Open is called. Any call to Open before setting the UsePool property to the value true will not cache a channel instance for pooling. Subsequent calls to Open after setting the UsePool property to the value true will share the same channel (in case there the end point and device setup of the connections opening match together).
