Libraries:
Simulink Real-Time / IP

Description

The TCP Receive block receives data sent from a remote client device to a server application on a target computer.

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 — Allow data reception

integer

When Enable > 0, the block attempts to receive data sent to the remote device.

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.

Output

Data — Data that is received from the remote client

vector

The parameter Receive width determines the maximum size of the data vector.

Data Types: uint8

Length — Actual size of data vector

double

To test whether the number of data items exceeds the width of the data output port, use this value.

Parameters

Receive using — List of IP address and port pairs

x.x.x.x:y

This parameter is read-only.

The block receives the list of IP address and port pairs from the TCP configuration blocks in the model.

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

Programmatic Use

Block Parameter: socketAddPort

Receive width — Maximum expected length of data vector

1–65504

Maximum number of uint8 values that the block expects to receive from the client device.

Programmatic Use

Block Parameter: rcvWidth

Sample time — Sample time of block

-1 (default) | numeric

Enter the base sample time or a multiple of the base sample time. -1 means that the sample time is inherited.

Programmatic Use

Block Parameter: sampleTime
