Libraries:
Simulink Real-Time / IP

Description

The TCP Server block configures a TCP server.

Examples

Target to Development Computer Communication by Using TCP

Use TCP blocks to send data from the target computer to MATLAB running on the development computer.

• Open Model

Ports

Input

Enable — Connect block to remote Ethernet device

integer

If Enable is greater than zero, the block connects to the Ethernet device. Otherwise, the block does not connect to the Ethernet device.

Output

Status — Device returns a status of not connected or connected

0 | 1

The status value is one of:

• 0 — Not connected

• 1 — Connected

As a best practice, connect the Status output of a TCP configure block to the Enable input of the associated TCP Send and TCP Receive blocks.

Parameters

Use host-target connection — Use Ethernet connection between the development computer and target computers

'off' (default) | 'on'

Dependency

When you select this parameter, it deactivates the Server IP address parameter and excludes the ports 1 through 1023 and 5500 through 5560 from use by TCP.

Programmatic Use

Block Parameter: useHostTargetConn

Server IP address — IP address of the server device that is being configured

x.x.x.x

If you are using a dedicated Ethernet card, this value must match the IP address configured for the Ethernet card on the target computer.

Programmatic Use

Block Parameter: serverAddress

Server port — IP port of the server device that is being configured

1–65535

The combination of Server IP address and Server port must be unique.

Ports 1 through 1023 and 5500 through 5560 are reserved for Simulink Real-Time communications.

Programmatic Use

Block Parameter: serverPort
