Port SERVICEACCESS - TCP-CLIENT-SOCKET 🛈¶

socket-based TCP client

Stimulation¶

This port has no stimulus capabilities.

Properties 🛈¶

Name	Default value	Valid values	Type	Description
Receive buffer size	1000		int	Number of messages which can be recorded in the receive buffer (ring buffer)
IP version	IPv4	[IPv4, IPv6]	string	Selection of the IP version used
Keep cyclic sending active	☐		bool	If the check mark is set, the cyclical sending of packets is only stopped at port stop or by the explicit call to ‘StopSendPacketCyclic’. Otherwise (default), the cyclic sending is already terminated at the end of the test.

Jobs 🛈¶

ClearReceiveBuffer¶

Clears the ecu.test high-level receive buffer. Low-level buffers in the driver are not cleared.

CloseConnection¶

Closes opened TCP connection

Connect¶

Establishes a TCP connection

Parameter

Name	Default value	Type	Description
SoKeepAlive	None	int	Keep Alive: None = ignore all keep-alive Parameters, 0 = keep-alive inactive, 1 = keep-alive active
TargetHost	‘192.168.0.1’	string	Hostname or IP for outgoing TCP connection
TargetPort	30490	int	Port for outgoing TCP connections
TcpKeepIdle	None	int	is the time in seconds without receiving data or confirmation packets for the connection until the first keep-alive packet will be transmitted. If None, this option will not be changed.
TcpKeepIntvl	None	int	The keep-alive interval is between two consecutive keep-alive repetitions if no confirmation of the previous keep-alive packet was received. If None, the option will not be changed.

ConnectionInfo¶

Provides IP address and port of connected network end point.

Return value

Name	Available if	Default value	Valid values	Type	Description
result				string	Tuple of IP address (str) and port (int) or NotPresent

ReceivePacket¶

Returns a packet from the receive buffer and removes it from there

Return value

Name	Available if	Default value	Valid values	Type	Description
result				string	Return value as ByteStream or NotPresent

ReceiveSomeIpMessage¶

Returns a packet from the receive buffer, interprets it and filters the MessageId if necessary. If MultipleResults are enabled, a list with more than one object might be returned. The packet will be removed from the receive buffer.

Parameter

Name	Default value	Valid values	Type	Description
InterpretAs	‘PacketSomeIp’	[‘PacketSomeIp’, ‘PacketSomeIpSd’]	string	Specifies which class a package is to be interpreted by. A packet is only returned if it could be successfully interpreted.
MessageId			object	MessageIds which have to match for passing (empty / int / list with ints)
MultipleResults	False	[False, True]	bool	Boolean, if enabled a list with result objects will be returned

Return value

Name	Available if	Default value	Valid values	Type	Description
result				string	Return value of specified type, list of it or NotPresent

SendPacket¶

Send data

Parameter

Name	Available if	Default value	Valid values	Type	Description
Data				string	String, payload as a ByteStream

StartSendPacketCyclic¶

Starts cyclic Transmission of a specified message

Parameter

Name	Default value	Type	Description
CycleTime	500	int	Cycle time [ms]
CyclicHandle		int	CyclicHandle can be defined manually. It must be an integer value greater than 0. Collision detection against already defined handles will not be performed.
Payload		object	Payload of the message to be sent cyclically. Either a byte stream can be specified directly or an object from a UserPyModule defined class. Further information on using the payload can be found in the help (Tool tracetronic: Ethernet).

Return value

Name	Available if	Default value	Valid values	Type	Description
CyclicHandle				int	Handle for targeted deactivation of cyclic transmission of that particular message.

StopSendPacketCyclic¶

Stops cyclic transmission

Parameter

Name	Available if	Default value	Valid values	Type	Description
CyclicHandle				int	Handle of a message to stop its cyclic transmission. If None is specified, cyclic transmission of all messages is stopped.
