Cost-effective reference design for IO-Link master module

Overview

TopologyOther Topology
IC revisionMARCH 2026

Description

This reference design accelerates the development of IO-Link controller gateways by implementing an 8-port IO-Link gateway that supports a cycle time of up to 400 μs, COM3, 1 A per port on L+, and an additional DI/DO. The design supports various Ethernet-based industrial protocols such as EtherCAT®, PROFINET®, Ethernet/IP, and Modbus® Transmission Control Protocol (TCP) using the integrated AM261xIndustrial Communication Subsystem (ICSS). The hardware design has been tested and developed to meet industry standard EMI/EMC requirements.

Features

8-port IO-Link controller with support for 1 A per port, COM3, 400 μs10/100 Mbit Multi-Protocol Industrial EthernetSupport for EtherCAT, Profinet, Ethernet/IP, MQTT, ModbusEMI/EMC tested design

Typical applications

  • Communication module
  • Stand-alone remote IO
