IO753: Modbus TCP Master protocol communication from Simulink

IO753: Modbus TCP Client I/O Module

Modbus TCP Client I/O module, with Simulink^® driver blocks

The IO753 I/O module is a Modbus TCP module to connect real-time target machines to external industrial devices such as motor controllers, sensors, I/O stations and robots.

The IO753 handles the complete data exchange between the connected Modbus TCP servers and the real-time application. The data exchange is processed via a dual-port memory. The module acts as one Modbus TCP client exclusively.

This I/O module is ideal for rapid control prototyping of industrial devices such as programmable logic controllers (PLC) and hardware-in-the-loop simulations using MATLAB^® and Simulink^® for testing industrial equipment such as motor controllers.

The IO753 I/O module is fully compatible with the Simulink^® Real-Time™ workflow. The extensive Simulink^® Real-Time™ driver blockset offers comprehensive functionality and firmware updates are easily available, as the Setup driver block downloads microcontroller firmware each time a target application is initialized.
