Interfaz TCP/IP

Comunicación mediante clientes y servidores TCP/IP

El Protocolo de Control de Transmisión (TCP) es un protocolo de transporte que se ejecuta sobre el Protocolo de Internet (IP) y es uno de los protocolos de red más utilizados. La compatibilidad de Instrument Control Toolbox™ con la comunicación TCP/IP incluye la capacidad de crear clientes y servidores. La compatibilidad con clientes TCP/IP permite utilizar la comunicación mediante sockets de red para conectarse a hosts remotos desde MATLAB® para leer y escribir datos binarios y ASCII. La compatibilidad con servidores TCP/IP permite crear un socket de red para la comunicación entre MATLAB y un único cliente.

Utilice tcpclient para crear un cliente TCP/IP que se conecte a un servidor o hardware y realice operaciones de lectura y escritura. Utilice tcpserver para crear un servidor TCP/IP.
