1 Introduction

PROFINET® is an open real-time communication protocol designed to exchange data between controllers and devices in an automation setting using industrial Ethernet. More detailed information about PROFINET® can be found in PROFINET® System Description. This document goes over the Ethernet PHY requirements and provides a few options, with their configurations, for immediate use in a PROFINET® system. Ethernet PHYs are only one component in a PROFINET® system, Texas Instruments also provides processors that function with PROFINET® , please refer to PROFINET® on TI's Sitara™ Processors.
