Libraries:
Simulink Real-Time / IP

Description

The TCP Receive block receives data sent from a remote client device to a server application on a Speedgoat^® 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
