IO752: PROFINET Device I/O Module

Configurable PROFINET Device I/O module, with Simulink® driver blocks

The IO752 I/O module is a PROFINET module to connect real-time target machines to external devices.

The IO752 handles the complete data exchange between the connected PROFINET Controller and the real-time application. The data exchange is processed via a dual-port memory. The module acts as one PROFINET Device exclusively. 

This I/O module is ideal for rapid control prototyping of devices in industrial automation plants such as motor controllers, sensors, I/O stations, and robots. Furthermmore, the IO752 can be used to perform hardware-in-the-loop (HIL) simulations for PLC testing, virtual commissioning, and factory acceptance tests using MATLAB® and Simulink®.

The IO752 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.
