Port SERVICEACCESS - TCP-SERVER-SOCKET¶

TCP server network stack based on LwIP

Stimulation¶

This port has no stimulus capabilities.

Properties 🛈¶

Name	Default value	Type	Description
Network name		string	Name of the network as defined in SIL Kit Config yaml.
Controller name		string	Name of the controller as defined in SIL Kit Config yaml.
Receive buffer size	1000	int	Number of messages which can be recorded in the receive buffer (ring buffer)
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 and prevents reconnect

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 (e.g. ByteStream(“00:00”))

StartAccepting¶

Starts accepting TCP connections

Parameter

Name	Default value	Valid values	Type	Description
DevGw			string	String (Format: 192.168.0.1 / fd48:a7e0:36c1:42b6::1), Empty when the gateway is not needed
DevIp			string	Local IP address as a string (format: 192.168.0.1 / fd48:a7e0:36c1:42b6::1). It must be located in the same subnet as the IP address of the device under test, and must not be equal to the IP address of another participant or the IP address which the operating system assigned to the selected network interface.
DevSubnetMask	‘Default’		string	For IPv4 addresses a subnet mask or prefix length can be given (format: ‘255.255.255.0’ or ‘24’). ‘default’ uses the default subnet mask of the IP address’s (DevIp) network class. For IPv6 only a prefix length is accepted and the value ‘default’ is not supported.
EthSrcMac	‘Default’		string	String (format: 00:11:FF:1E:32:FF), leave ‘Default’ if the default MAC address should be used
ListenPort	30490		int	Port for incoming TCP connections
VlanCfi	0		int	Integer, is only used if VLAN is configured
VlanOption	‘no tagging’	[‘no tagging’, ‘single tagging’]	string	Used VLAN setting
VlanPcp	0		int	Integer, is only used if VLAN is configured
VlanVid	1		int	Integer, only used if VLAN tagging is enabled

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.
