Why Ethernet/IP Matters in Modern Industrial Automation

Ethernet/IP (Ethernet Industrial Protocol) has become one of the most widely adopted industrial communication standards globally. Built on standard Ethernet and the Common Industrial Protocol (CIP), it allows manufacturers to unify real-time control, diagnostics, configuration, and enterprise data exchange on a single network.

As factories evolve toward smart manufacturing and IIoT-driven operations, Ethernet/IP plays a crucial role by:

  • Bridging shop-floor devices with MES, SCADA, and cloud platforms
  • Supporting both time-critical I/O data and non-time-critical configuration data
  • Leveraging standard Ethernet hardware for cost-effective scalability

RAPIDSEA’s Ethernet/IP stack is designed to help OEMs and automation developers adopt Ethernet/IP faster, with fewer risks and lower integration effort.

What Is RAPIDSEA Ethernet/IP Protocol Stack?

The RAPIDSEA Ethernet/IP Protocol Stack is a production-ready, embedded software implementation of the ODVA Ethernet/IP specification. It enables industrial devices to communicate reliably using explicit and implicit messaging, while remaining fully interoperable with multi-vendor Ethernet/IP ecosystems.

Whether you are building PLCs, remote I/O modules, gateways, drives, or smart sensors, RAPIDSEA provides a robust Ethernet/IP foundation.

Ethernet/IP OSI Layer Mapping

Understanding the Architecture

Our stack is designed with a modular approach that mirrors the OSI framework, ensuring seamless interoperability:

  • Physical & Data Link (Layers 1-2): Fully compliant with IEEE 802.3, supporting various media from copper to optical fiber.
  • Network Layer (Layer 3): Utilizes standard IP addressing for universal identification across complex network topologies.
  • Transport Layer (Layer 4): Employs TCP for reliable, connection-oriented Explicit Messaging and UDP for high-speed, connectionless Implicit (I/O) Messaging.
  • Application Layer (Layers 5-7): This is where the CIP (Common Industrial Protocol) shines, organizing data into an object-oriented model for unified device profiles and services.

This transport-agnostic approach ensures future-proof integration as automotive networks evolve.
