TCP/IP-Schnittstelle
Das Transmission Control Protocol (TCP) ist ein Transportprotokoll, das auf dem Internet Protocol (IP) aufsetzt und zu den am häufigsten verwendeten Netzwerkprotokollen zählt. Die Unterstützung von Instrument Control Toolbox™ für die TCP/IP-Kommunikation umfasst die Möglichkeit, Clients und Server zu erstellen. Die TCP/IP-Client-Unterstützung ermöglicht es Ihnen, über Netzwerk-Socket-Kommunikation von MATLAB® aus eine Verbindung zu entfernten Hosts herzustellen, um sowohl Binär- als auch ASCII-Daten zu lesen und zu schreiben. Die TCP/IP-Serverunterstützung ermöglicht es Ihnen, einen Netzwerk-Socket für die Kommunikation zwischen MATLAB und einem einzelnen Client zu erstellen.
Verwenden Sie tcpclient, um einen TCP/IP-Client zu erstellen, der eine Verbindung zu einem Server oder einer Hardware herstellt und Lese- und Schreibvorgänge durchführt. Verwenden Sie tcpserver, um einen TCP/IP-Server zu erstellen.

TCP/IP-Kommunikation
- 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.
TCP/IP-Client
- 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.
TCP/IP-Server
- 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.
TCP/IP Explorer-App

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.
