Interfaz TCP/IP

Comunicación mediante clientes y servidores TCP/IP

El Protocolo de control de transmisión (TCP) es un protocolo de transporte superpuesto al Protocolo de Internet (IP) y es uno de los protocolos de red más utilizados. El soporte de Instrument Control Toolbox™ para la comunicación TCP/IP incluye la capacidad de crear clientes y servidores. La compatibilidad con clientes TCP/IP le permite utilizar la comunicación por socket de red para conectarse a hosts remotos desde MATLAB^® para leer y escribir datos binarios y ASCII. La compatibilidad con servidor TCP/IP le permite crear un socket de red para la comunicación entre MATLAB y un solo 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.
