Input ports

Name	Width	Description
MessagesToSend	<NumberOfMessagesToSend>	A vector of values received from client.

Output ports

Name	Width	Description
MessagesReceived	<NumberOfMessagesToReceive>	A vector of values to be sent to client.

Configuration parameters

Name	Width	Description
ServerIPAddress	1	The server IP address.
ServerPortNumber	1	The server port number.
NumberOfMessagesToSend	1	The number of double values to send.
NumberOfMessagesToReceive	1	The number of double values to receive.
SetInitialMessagesToReceive	1	If enabled the initial value of MessagesReceived can be set by a configuration parameter. If not it is zero by default.
InitialMessagesToReceive	<NumberOfMessagesToReceive>	The initial value of MessagesReceived.
ShowTCPResultOnScreen	1	Log the activity of the TCP server to file and console.
ReceiveInMultipleRounds	1	This enables the possibility to receive the output vector of size NumberOfMessagesToReceive through several UDP packets.
CommunicationInterval	1	The interval between reading and writing messages.
CommunicationStartingTime	1	The startup time for reading and writing messages.
