8 Port IO-Link Master Reference Design

TIDA-010016

Design files

Overview

PLC applications requiring fast timing and fast cycle time can now be realized using this reference design which implements, an eight-port IO-Link master. It can be used to build a remote IO gateway to connect to OPC UA, Profinet, EtherCAT or Ethernet IP. A PRU-based frame handler enables a very flexible way of timing and time synchronization. This design helps build a very universal and scaleable IO-Link master.

Features
  • Eight IO-link ports
  • Supports COM1, COM2, COM3
  • Supports 400-µs cycle time
  • All ports overcurrent protected and limited
  • 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.
