Eight-port IO-Link master reference design

TIDA-010234

Design files

Overview

This reference design implements an IO-Link master with fast and deterministic timing with eight ports. Each port can be operated with independent bit rate and cycle timing. This design can be used to build a remote IO gateway to connect to OPC UA, Profinet, EtherCAT or Ethernet IP. A PRU-based frame handler provides timing flexibility and synchronization.

Features
  • Eight IO-Link ports
  • Supports IO-Link transmission rates COM1, COM2 and COM3
  • Supports 400-μs cycle time
  • 500-mA current per port
  • All ports feature overcurrent protection and limiting
  • PRU frame handler enables flexible timing

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
