Direct Interface Communication in Simulink

Send and receive data in Simulink^® models

The Instrument Control Toolbox™ provides blocks for communicating with instruments and using the serial, TCP/IP, and UDP interfaces in Simulink. The blocks in the Instrument Control Toolbox Block Library and examples showing how to use them are listed below.

Blocks

Serial Configuration	Configure parameters for serial port
Serial Receive	Receive binary data over serial port
Serial Send	Send binary data over serial port
TCP/IP Receive	Receive data over TCP/IP network from specified remote machine
TCP/IP Send	Send data over TCP/IP network to specified remote machine
UDP Receive	Receive data over UDP network from specified remote machine
UDP Send	Send data over UDP network to specified remote machine
VISA	Communicate with VISA resources (Since R2023b)

Topics

Open Instrument Control Toolbox Block Library
Access the Instrument Control Toolbox block library in two ways.
Send and Receive Data over TCP/IP Network
Send data to an echo server using TCP/IP and read that data back into a model.
Enable Blocking Mode in Receive and Send Blocks
Make your simulation wait while the block receives or sends data.
Timing in Hardware Interface Models
Determine block execution frequency and relate to real-world time.
