IO750: EtherCAT Subordinate Device I/O Module

Configurable EtherCAT Subordinate Device I/O Module and Simulink® Driver Blocks

The IO750 I/O module is an EtherCAT module to connect real-time target machines to external devices.

The IO750 handles the complete data exchange between the connected EtherCAT main device and the real-time application. The data exchange is processed via a dual-port memory. The module acts as one EtherCAT subordinate device exclusively.

This I/O module is ideal for closed-loop controls and hardware-in-the-loop simulations using MATLAB® and Simulink®.The IO750 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

  • 2x 10BASE-T/100BASE-TX isolated, auto-crossover function Ethernet connectors enable easy network integration
  • Supports distributed clocks and synchronization of the real-time application
  • DMA enables fast data exchange on PCI bus
  • Acyclic communication
