This class enables communications via TCP interface. It creates a Winsock Server on Localhost (127.0.0.1 Port number: 5000), or a specified IP address and port number (not tested). It needs to be awaked by connections from an external process (Client). At present it can only send messages consist of double precision numbers (8 Bytes).

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.
