Interface TCP/IP
Le protocole de contrôle de transmission (TCP) est un protocole de transport superposé au protocole Internet (IP) et est l'un des protocoles réseau les plus utilisés. La prise en charge de Instrument Control Toolbox™ pour la communication TCP/IP inclut la possibilité de créer des clients et des serveurs. La prise en charge du client TCP/IP vous permet d'utiliser la communication par socket réseau pour vous connecter à des hôtes distants depuis MATLAB® pour lire et écrire des données binaires et ASCII. La prise en charge du serveur TCP/IP vous permet de créer un socket réseau pour la communication entre MATLAB et un seul client.
Utilisez tcpclient pour créer un client TCP/IP qui se connecte à un serveur ou à du matériel et effectue des opérations de lecture et d'écriture. Utilisez tcpserver pour créer un serveur TCP/IP.

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 protcol. 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.
