IO752-32: I/O Module for PROFINET

32-Node Simulator I/O Module for PROFINET

The IO752-32 is a PROFINET device module that empowers users to simulate large-scale industrial installations, infrastructure and maritime vehicles; for example, production plants, ships, wind farms, solar parks, power grids, tunnels and train networks.

The module physically emulates a high number of real-time capable PROFINET devices that communicate with the remote PROFINET controller as in a real industrial plant. Each device is represented by an independent network transceiver, ensuring short response times.

The IO752-32 is ideal for hardware-in-the-loop (HIL) simulations using MATLAB® and Simulink®. It allows manufacturers of industrial systems and equipment to test plant controllers and realize virtual commissioning with digital twins: manufacturers can implement the plant behavior, operation modes and states in Simulink, add IO752-32 driver blocks to exchange data with the plant controller and use Simulink Test™ for error-injection, automated testing and test reporting.

* MTBF values shown are based on calculation according to MIL-HDBK-217F and MIL-HDBK-217F Notice 2. Environment GB 20 °C. The MTBF calculation is based on component FIT rates provided by the component suppliers. If FIT rates are not available, MIL-HDBK-217F and MIL-HDBK-217F Notice 2 formulas are used for the FIT rate calculation.
** Custom firmware is available supporting more sub-modules and application relations
