IO641: PROFIBUS DP Master I/O Module

Configurable PROFIBUS DP master I/O module with one port, with Simulink driver blocks

The IO641 I/O module is a PROFIBUS module to connect real-time target machines to external industrial devices. 

The IO641 handles the complete data exchange between the connected PROFIBUS DP Slaves and the real-time application. The data exchange is processed via a dual-port memory. The module acts as one PROFIBUS Master 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 IO641 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.

Key Features

  • Exchange data with up to 125 devices via the PROFIBUS DP protocol
