CertificateValidationCallback()

bool lib60870.CS104.ClientConnection.CertificateValidationCallback	(	object	sender,
		X509Certificate	cert,
		X509Chain	chain,
		SslPolicyErrors	sslPolicyErrors )

Callback method to handle certificate validation in SSL/TLS communication. It checks various conditions such as certificate chain validation, specific certificate validation, and SSL policy errors to determine whether the certificate is valid for the current connection.

Parameters

sender	The source of the event. This is typically the SSL/TLS connection.
cert	The certificate being validated.
chain	The certificate chain associated with the certificate.
sslPolicyErrors	The SSL policy errors that occurred during certificate validation.

Returns

Returns true if the certificate is considered valid based on the specified criteria; otherwise, returns false.

GetApplicationLayerParameters()

ApplicationLayerParameters lib60870.CS104.ClientConnection.GetApplicationLayerParameters

(

)

Gets the connection parameters.

Returns

The connection parameters used by the server.

Implements lib60870.CS101.IMasterConnection.

MasterConnection_hasUnconfirmedMessages()

bool lib60870.CS104.ClientConnection.MasterConnection_hasUnconfirmedMessages

(

)

Checks if there are any unconfirmed messages in the low-priority or high-priority queues.

Returns

true if there are unconfirmed messages in either the low-priority or high-priority queues; false if no unconfirmed messages are found.

SendACT_CON()

void lib60870.CS104.ClientConnection.SendACT_CON	(	ASDU	asdu,
		bool	negative )

Sends an Activation Confirmation (ACT_CON) ASDU with the specified negative flag.

Parameters

asdu	The ASDU to be sent as an Activation Confirmation (ACT_CON).
negative	A boolean flag indicating whether the Activation Confirmation is negative.

Implements lib60870.CS101.IMasterConnection.

SendACT_TERM()

void lib60870.CS104.ClientConnection.SendACT_TERM

(

ASDU

asdu

)

Sends an Activation Termination (ACT_TERM) ASDU with a negative flag set to false.

Parameters

asdu	The ASDU to be sent as an Activation Termination (ACT_TERM).

Implements lib60870.CS101.IMasterConnection.

void lib60870.CS104.ClientConnection.SendASDU

(

ASDU

asdu

)

Send a response ASDU over this connection.

Exceptions

Throws an exception if the connection is no longer active (e.g. because it has been closed by the other side).

Parameters

asdu	The ASDU to send

Property Documentation

IsActive

bool lib60870.CS104.ClientConnection.IsActive

getset

Gets or sets a value indicating whether this connection is active. The active connection is the only connection that is answering application layer requests and sends cyclic, and spontaneous messages.

true if this instance is active; otherwise, false.
