Interfaccia TCP/IP
Il Transmission Control Protocol (TCP) è un protocollo di trasporto che si sovrappone all'Internet Protocol (IP) ed è uno dei protocolli di rete più utilizzati. Il supporto di Instrument Control Toolbox™ per la comunicazione TCP/IP include la possibilità di creare client e server. Il supporto client TCP/IP consente di utilizzare la comunicazione tramite socket di rete per connettersi a host remoti da MATLAB® per leggere e scrivere dati sia binari che ASCII. Il supporto del server TCP/IP consente di creare un socket di rete per la comunicazione tra MATLAB e un singolo client.
Utilizza tcpclient per creare un client TCP/IP che si connette a un server o a un hardware ed esegue operazioni di lettura e scrittura. Utilizza tcpserver per creare un server TCP/IP.

Comunicazione TCP/IP
- TCP/IP Communication Overview
Use network socket communication to connect to remote hosts from MATLAB for reading and writing data over TCP/IP. - TCP/IP and UDP Comparison
Compare the TCP/IP and UDP protocols to determine which to use.
Client TCP/IP
- Create TCP/IP Client and Configure Settings
Connect to remote hosts or hardware from MATLAB for reading and writing data over TCP/IP. - Write and Read Data over TCP/IP Interface
Write and read data to and from the remote host connected to thetcpclientobject. - Use Callbacks for TCP/IP Communication
Enhance TCP/IP communication by executing a callback function when a specified event occurs. - Transition Your Code to tcpclient Interface
Create TCP/IP client connections usingtcpclientinstead oftcpip.
Server TCP/IP
- Communicate Using TCP/IP Server Sockets
Communicate between a client and MATLAB, or between two instances of MATLAB. - Transition Your Code to tcpserver Interface
Create TCP/IP server connections usingtcpserverinstead oftcpip.
Applicazione TCP/IP Explorer

Communicate Binary and ASCII Data to an Echo Server Using TCP/IP
Set up an echo server and communicate with it using TCP/IP by creating a tcpclient object. Binary data and terminated string data are sent to the server and the server echoes the same data back to the client.
Communicate Between a TCP/IP Client and Server in MATLAB
Use the tcpserver and tcpclient functions to create a TCP/IP client and TCP/IP server in MATLAB® and then send data between them over the TCP/IP protocol. You can run this example three different ways:
Read Data from Arduino Using TCP/IP Communication
Enable callbacks to read sine wave data from an Arduino® Uno using the tcpserver interface. The Arduino is configured as a TCP/IP client and connects to the TCP/IP server created in MATLAB® using tcpserver.
Reading Inphase and Quadrature (IQ) Data from a Signal Analyzer over TCP/IP
Acquire IQ Data from a signal analyzer over a TCP/IP interface.
Communicate Between TCP/IP Client Receive Block and TCP/IP Server in MATLAB
Send data over TCP/IP using TCP/IP Client Receive block and TCP/IP server.
TCP/IP Client Block Communication with Arduino Server
Send data to Arduino server using TCP/IP Send and read it back using TCP/IP Receive.
