In industrial automation, keeping device firmware up to date is critical for maintaining security, reliability, and compliance with evolving regulations. With the introduction of the Cyber Resilience Act (CRA), firmware updates for connected devices will soon become mandatory, creating an urgent need for standardized methods to manage these updates efficiently across diverse equipment. Currently, firmware updates often require vendor-specific tools, which can complicate maintenance and increase operational risk in multi-vendor environments. 

This paper presents a proposal for a common, harmonized, and open approach for performing firmware updates over EtherNet/IP. By specifying CIP Object(s) and services as a standardized, vendor-independent interface for firmware updates and exploring a common packaging format for firmware, the approach aims to simplify deployment, reduce errors, and streamline device management. Key use cases and implementation strategies are outlined, highlighting how the solution can accommodate the needs of both simple and complex devices. 

Adopting such a standardized approach provides significant benefits to end users, enabling a single tool to manage firmware updates across an entire facility regardless of the number of vendors involved. This reduces the operational burden of managing multiple update processes, enhances consistency and security, and aligns with regulatory compliance requirements.  

By providing a vendor-neutral framework for firmware updates, ODVA members and the broader EtherNet/IP community can adopt a more efficient, reliable, and scalable approach to maintaining device firmware, supporting both operational efficiency and regulatory compliance.

EtherNet/IP In-Cabinet system replaced hardwiring between devices with a single composite media and extended EtherNet/IP communication directly into low-cost industrial control components. As adoption grows, there is increasing demand to support functional safety applications within this ecosystem while maintaining performance, electromagnetic compatibility (EMC), and multi‑vendor interoperability. This paper examines emerging EtherNet/IP In‑Cabinet Safety use cases, key technical challenges associated with implementation—including EMC behavior and system safety response time—in achieving safe, deterministic communication on Single‑Pair Ethernet. The paper explores key new 10Base-T1M features and its compatibility when used in existing EtherNet/IP In-Cabinet system. The paper further discusses ecosystem expansion through third‑party development toolkits and conformance‑ready implementations, enabling broader vendor participation and accelerating innovation. The intent is to provide guidance to device vendors, system integrators, and technology partners on achieving safe, interoperable, and scalable in‑cabinet safety architectures using EtherNet/IP.

This article introduces a compact, robust connector generically referred to as the ix, a next-generation miniaturized Ethernet connector system standardized under IEC 61076-3-124, engineered to replace RJ45 in industrial automation environments. At roughly one-quarter the volume of RJ45, the ix gives design engineers the dimensional headroom to integrate Ethernet connectivity into space-constrained assemblies unsuitable for standard RJ45 jacks. Despite its compact form factor, the interface delivers superior mechanical robustness through dual metal locking latches and through-hole reflow shield pins, yielding PCB retention forces that exceed RJ45. Electrically, the 360-degree shielded, symmetric-pair contact architecture attains inductance values of 0.14 – 0.45 nH – an order of magnitude below RJ45 – enabling Cat.6A-certified for 10GBASE-T transmission with enhanced EMI/ESD immunity. The connector supports PoE++ (IEEE 802.3bt) and offers IP20 and IP65/67 variants, including an IP20 variant with integrated magnetics. Adopted across PROFINET, EtherCAT, GigE Vision, and CC-Link IE TSN protocols, the ix is manufactured by multiple independent vendors including Hirose, HARTING, and Amphenol, ensuring open-market pricing and broad supply chain availability for factory automation, robotics, machine vision, and servo drive applications.

The emergence of Industry 4.0 has accelerated the adoption of reconfigurable and software-defined manufacturing systems. These systems rely increasingly on programmable controllers, distributed input/output devices, industrial Ethernet networks, and dynamically integrated safety functions. Functional safety communication profiles such as CIP Safety apply the black-channel principle defined in IEC 61784-3 [2]. Under this principle, standard communication infrastructure may be used to transport safety-related information, provided that an independent end-to-end safety communication layer detects or controls the assumed communication errors.

CIP Safety is specified in Volume 5 [1] of the ODVA CIP Networks Library and standardized as Functional Safety Communication Profile 2/1 in IEC 61784-3-2 [2]. It uses safety Cyclic Redundancy Checks (CRCs), timestamps, rollover counts, time-expectation monitoring, producer and consumer identification, redundant data encoding, cross-checking, and connection supervision. Collectively, these mechanisms address communication failures [7] such as message repetition, loss, insertion, incorrect sequence, corruption, delay, unintended coupling, increased data age in bridges, and addressing errors.

This paper evaluates the coverage provided by these mechanisms within the CIP Safety producer–consumer model. The assessment considers single-cast and multicast connections, the required Extended Format, and the deprecated Base Format where legacy compatibility remains relevant. Communication Failure Mode and Effects Analysis (FMEA) [4] is extended with product-level implementation faults, including memory corruption, partial Direct Memory Access overwrite, timestamp-processing errors, scheduling faults, incorrect configuration handling, and corruption occurring before CRC generation or after message validation.

The analysis demonstrates that protocol compliance does not, by itself, establish complete product or system safety. Although CIP Safety provides strong detection of communication-channel errors, limitations may remain in root-cause identification, diagnostic granularity, system availability, internal non-interference, semantic validation of process values, and allocation of the complete system reaction time. The paper therefore proposes an assessment methodology that maps communication FMEA, product FMEA [4], Functional Requirement Specification identifiers, and applicable test evidence. It also identifies system-level gaps and proposes architectural controls, interface requirements, fault-injection tests, and sequence-based evaluations for consideration by product developers, safety assessors, and standards working groups (WG).

EtherNet/IP devices are becoming more complex, and the associated device configuration in modern automation systems must balance rich, device-specific behavior with cloud-scale deployment, interoperability, and predictable host integration. The paper will describe an approach that combines stateless business logic, schema-versioned APIs to address this challenge. In this model, device vendor-supplied applications remain stateless with interactions where the data models are provided through asynchronous events, while controller configuration applications own project state, sequencing, and consistency boundaries. Operational workflows are exchanged as CloudEvents over MQTT using versioned schemas, with explicit separation between transport responsibilities and profile logic. Enabling moving communications to the Edge, CIP direct-to-device operations use correlated request/response tokens and repeatable transport contracts, enabling deterministic execution for one-shot and polling scenarios without introducing cross-request state leakage in services.

In parallel, the proposed solution preserves compatibility with established artifacts and practices, including static descriptors such as EDS and EDDL-derived structures, while introducing dynamic registration and extensible JSON schema contracts for host/device coordination. The resulting architecture is expected to improve interoperability across hosts and device families, reduce integration risk for device software developers, and provide a scalable baseline for more complex configuration, online diagnostics, and multi-step device workflows to be defined by device vendors. This paper provides an overview of the architecture decisions, implementation implications, and ecosystem benefits for vendors, host developers, and end users.

The European Union Cyber Resilience Act (CRA) introduces mandatory cybersecurity requirements for products with digital elements that are placed on the European market. For manufacturers of industrial communication products and EtherNet/IP devices in particular, compliance is not only a regulatory obligation but also a practical necessity for reducing operational risk, protecting customer production environments, and preserving market access.

This paper translates the high-level themes of the source presentation into a practical manufacturer-oriented approach. It explains how CRA obligations intersect with industrial automation, secure industrial communication, IEC 62443, and product lifecycle management. It also proposes a step-by-step method for moving from product scoping to security context definition, threat analysis, risk assessment, countermeasure selection, documentation, and post-market vulnerability management.

The central argument is that CRA compliance should not be treated as a purely legal exercise. It should be used as a structured engineering discipline that strengthens product security, improves operational resilience, and creates clearer evidence for audits, customers, and internal development teams.

Recent enhancements to The CIP Networks Library Volume 1 modify requirements for device Electronic Data Sheets (EDS) and for the first time introduce requirements for applications that interpret them. The specification has historically left many features optional to promote EtherNet/IP adoption. In some cases, this led to interoperability issues. In others it created a disincentive for feature adoption due to not knowing if any other products supported a feature. The new requirements are expected to enhance consistency, interoperability, and ease device vendor development efforts by providing a predictable baseline for EDS file support.

This paper presents an overview of these changes, their impact on host applications and EDS files, and the resulting benefits to the EtherNet/IP ecosystem and our end users.

As industrial automation systems continue to scale and increasingly integrate with enterprise IT infrastructures (for example in data centers), IPv6 is becoming a critical technology for the future evolution of the Common Industrial Protocol (CIP). IPv6 enables new approaches to scalability, address management, and network interoperability that are difficult to achieve with IPv4-based solutions.

Since the last ODVA Industry Conference, significant progress has been made toward introducing IPv6 support into EtherNet/IP and the entire CIP ecosystem, including CIP Safety. Building on the roadmap outlined in “An IPv6 Roadmap for EtherNet/IP”, this paper provides an update on the current state of the work and highlights recent technical results. It discusses the challenges encountered when designing IPv6-related CIP Objects, including object modelling, address management, and interactions with existing CIP services, and explains how these challenges have been addressed.

It also presents the technical details of device provisioning at scale using IPv6 within EtherNet/IP networks. It discusses how IPv6, combined with existing CIP mechanisms and well-known IP technologies, can be applied to simplify system deployment and commissioning workflows for customers, system integrators, and device vendors.

The paper concludes with a preview of the next steps on the IPv6 roadmap for EtherNet/IP and outlines areas of ongoing work, providing insight into how IPv6 capabilities are expected to evolve within the CIP ecosystem.

A major manufacturer of plastic packaging products sought to modernize its inventory management system for raw plastic pellet storage silos. The existing level measurement technology proved intermittently unreliable, particularly during the critical filling process. This lack of reliability introduced the risk of overfilling, leading to potential material loss, safety concerns, and operational inefficiencies.

The customer required a simple, dependable, repeatable, real-time solution that could seamlessly integrate with their existing Rockwell PLC infrastructure, provide advanced digital data, standardized diagnostics and enable secure remote support over the company’s network.

To meet these needs, a non-contact radar level measurement solution utilizing Ethernet-APL with Ethernet/IP protocol was implemented. This approach allowed for direct digital communication with the Rockwell PLC via an Ethernet-APL Field Switch simplifying installation while ensuring high-quality, real-time digital data transmission.

EtherNet/IP provides the tools to deploy standard Ethernet technology for manufacturing and process applications, improve connectivity between people, partners, processes, devices, and systems. This flexibility opens new opportunities for productivity and efficiency in industrial systems.

In this case study, we will examine the application in detail and demonstrate how Ethernet-APL using Ethernet/IP directly to the Rockwell PLC met the customer’s requirements for a safer level solution with simple installation, reliable performance, advanced data driven operational tools and enhanced secure remote support diagnostics capabilities.

This is a case study of the customer journey to install Ethernet APL sensors with EtherNET/IP protocol.

EZ-EDS has long served as a key tool for creating, editing, and validating EDS files within industrial communication ecosystems. As device description technologies evolve, new requirements introduced through xDS initiatives create both opportunities and challenges for tools that support EDS development workflows. To remain effective, EZ-EDS must adapt to these changes while continuing to provide a streamlined and reliable user experience for developers.

This paper presents a series of enhancements and extensions to EZ-EDS aimed at improving both functionality and usability. A primary focus is the introduction of support for new requirements associated with xDS, ensuring that the tool remains aligned with current and emerging specification needs. These updates address structural, validation, and workflow considerations essential to next-generation device description practices.

In addition to technical compliance, the paper examines broader usability improvements intended to simplify the development process for EDS authors. These enhancements include interface refinements and workflow optimizations designed to reduce complexity and improve efficiency. Together, these changes position EZ-EDS as a more capable, adaptable, and user-friendly platform for EDS development.

In the current industrial automation landscape cyber-securing the device in the network poses a big challenge. Securing EtherNet/IP CIP endpoints remains difficult when reliance is placed only on perimeter controls. Firewalls, segmentation, VPN, and (D)TLS wrappers protect the channel, but they do not by themselves decide whether a specific CIP object, service, or operational command is authorized for a given requester in the device’s current state or mode. However, there are many instances where these approaches are compromised, and packets reached the device to attack. Some published paper does not consider authentication, packet integrity enforcement & command validation [1]. The other paper [2] describes Intrusion Detection (IDS), not prevention. Therefore, packets will reach device, and device will process malicious data which poses threat to the device.

The proposed methods provide a practical multi-layer enforcement pipeline for CIP endpoints that composes existing ODVA CIP Security (Volume 8) profile with Confidentiality, User Authentication, and Device-Based Firewall where applicable. Therefore, it adds mode or state aware, object-level application policy.

The device based firewall performs traffic filtering at the device. CIP object, service and role checks are post-(D)TLS application policy which is performed after a secure channel and authenticated identity are verified.

Device keeps track of the session binding of requester identity to an active security context, role, CIP object access, operational-mode gates, fail-closed behavior, and mutual agreement of allowable object access at session setup.

Device defines and maintains its operational state and checks the current state with current requested operation state for authenticating the requester for further communication. It admits only commands permitted in that state which prevents authenticated but inappropriate configuration or control.

Device restricts the access of Common Industrial Protocol (CIP) objects based on the requester type and authenticity. Both the device and requestor have mutual agreement for accessing the CIP objects. CIP object access is restricted by requester role and an explicit mutual agreement at session setup. If there is any access request beyond the agreed objects or service access permission it will be rejected (fail-closed).

The Common Industrial Protocol (CIP) is widely used in industrial automation to enable interoperable communication between devices from multiple vendors. As the number and diversity of CIP-enabled products continue to grow, the need for standardized, machine-readable mechanisms to describe device capabilities, characteristics, and related metadata has become increasingly important. Such mechanisms can simplify integration with engineering tools, digital repositories, and emerging data-driven applications. 

This paper presents the development of an API based on the OpenAPI Specification to describe products that implement CIP. The proposed approach provides a consistent and structured method for accessing product information through a standardized REST interface, enabling automated interaction with product data across tools and platforms. 

The paper introduces a proposed OpenAPI definition designed to represent key product attributes, including device identity, supported features, and associated documentation. The definition is intended to promote interoperability while simplifying access to device information for system integrators, engineers, application developers, and data scientists. 

Several example use cases are presented to demonstrate how the proposed OpenAPI definition can be applied in practical scenarios. These examples illustrate how standardized API access can support activities such as device discovery, feature identification, and large-scale data harvesting. 

The results demonstrate how an OpenAPI-based approach can improve accessibility, automation, and interoperability in managing information related to CIP-enabled products and supporting modern industrial engineering workflows.

Accurate and reliable time synchronization has become a foundational capability for modern industrial automation systems. Applications such as motion control, coordinated drives, distributed I/O, expiration of credentials, and time correlated diagnostics increasingly depend on accurate time synchronization to maintain a common system time across controllers and devices. IEEE 1588 PTP is widely adopted in these applications due to its precision and scalability. However, IEEE 1588 PTP, like many other time synchronization technologies, was not originally designed with security as a primary consideration. As industrial systems become more connected and exposed, manipulation of system time—whether malicious or unintentional—represents a growing risk that can impact performance, reliability, and safety.

This session paper explores approaches for identifying and responding to security related topics for time synchronization technologies in industrial devices that utilize IEEE 1588 PTP and other common technologies. Since IEEE 1588 PTP is so important for CIP Motion, special attention is given to it. A proposed solution for securing IEEE 1588 PTP is given, which monitors time integrity at the CIP application layer, where deviations from expected behavior can be detected with minimal impacts to existing installations. The paper details that approach and examines tradeoffs of that solution against other potential solutions.

CIP Safety is based on the Black Channel concept defined in IEC 61784‑3, where the communication path is treated as unknown and potentially faulty, and safety integrity is achieved through end‑to‑end mechanisms in the Safety Communication Layer (SCL). These mechanisms provide a SIL 3 compatible residual error rate independent of the underlying network and lower protocol layers. However, current applications of IEC 61508-3 standard’s non‑interference requirements can impose stringent architectural constraints when integrating SIL 3 capable CIP Safety stacks into devices whose safety functions require only SIL 1 or SIL 2 to meet application needs.

This paper examines the implications of applying mixed‑criticality non‑interference rules—originally intended to prevent interference between safety‑related software elements—within a Black Channel communication model. It shows that requiring Systematic Capability (SC) 3 non‑interference down to supporting software, operating systems, and hardware can inadvertently mandate full SIL 3 platforms, even when system‑level risk analysis does not justify such integrity levels.

The recently adopted closed communication system option in CIP Safety resolves this tension. In closed systems where the system integrator controls the complete communication network, responsibility for achieving appropriate Systematic Capability shifts to the integrator—aligning with IEC 61508:2010 system design principles. This enables device developers to integrate CIP Safety onto platforms with SC levels proportional to their individual safety functions, while the integrator ensures overall system integrity. The paper concludes by outlining areas investigated within ODVA, including conformance policy interpretation and guidance.

Industrial networks are commonly defined through topology, protocol conformance, and connectivity. While these descriptors remain essential, they are no longer sufficient to explain the behavior of contemporary automation systems operating across distributed control, diagnostics, engineering access, segmentation boundaries, and cross-domain integration. This paper argues that new networks require a renewed examination of current heuristics in networking, particularly when industrial architectures are treated only as static communication infrastructures rather than as dynamic systems of interaction.

The paper develops a conceptual framework that reinterprets eight networking heuristics through an industrial lens, focusing on interaction density, connection paths, communication-function fit, concentration points, and coordination load, specifically, through EtherNet/IP. Drawing on network analysis and communication theory, it distinguishes which heuristics can be translated productively into industrial-network thinking and which must be qualified before they can support technical reasoning. The central finding is that industrial-network behavior cannot be inferred from protocol and topology alone. Architectural reach, resilience, and scalability are also shaped by how traffic and control dependencies are distributed, where bridges connect segmented domains, and where hubs emerge as either useful coordinators or failure concentrators. This paper proposes a more precise analytical approach to the interpretation of industrial systems already well understood by practitioners. By redefining industrial networks as interaction systems rather than static infrastructures, the paper offers a stronger conceptual basis for architecture review, segmentation strategy, concentration analysis, interoperability planning, and resilience-oriented design.

Industrial communication protocols are a foundational element of modern process and factory automation, enabling interoperability, real-time control, and efficient device integration. However, many widely deployed protocols were not originally designed with cybersecurity as a primary objective. Although standards development organizations have been steadily adding security functionality to these protocols, there are still many deployments that lack built-in security mechanisms such as authentication, authorization, integrity, and confidentiality.

To address this challenge, FieldComm Group, ODVA, OPC Foundation, and PROFIBUS & PROFINET International have collaborated to establish a shared operational environment and architecture overview for industrial communication protocols in alignment with EN 40000-1-2. Based on the EN 40000-1-2, in this technical paper, a structured risk-based methodology is applied to assess cybersecurity risks associated with commonly used industrial communication protocols and to define appropriate mitigation strategies.

The assessment confirms that in many cases, the use of industrial protocols relies heavily on additional compensating controls provided by the operational environment. Even as Ethernet-based protocols such as EtherNet/IP, HART-IP, OPC UA, and PROFINET offer enhanced security profiles, their usage depends on the risk assessment and operational environment of the end user.

As industrial robotics adoption accelerates, the need for standardized, vendor neutral integration between Programmable Logic Controllers (PLCs) and robot controllers has become increasingly critical. While the Standard Robot Controller Interface (SRCI) specification defines a comprehensive, PLC centric command and state model for robotic systems, it does not prescribe a Common Industrial Protocol (CIP) based transport suitable for EtherNet/IP environments. This paper proposes a new CIP profile that enables EtherNet/IP as a standardized transport for interacting with SRCI compliant robot and robot control equipment.

The paper examines the architectural and protocol considerations required to map SRCI capabilities onto CIP technologies, with emphasis on the SRCI Command formulation through EtherNet/IP connections and other applicable CIP technology capabilities. Key topics include transport mapping strategies, definition of communication and command state machines, fragmentation and reassembly of SRCI messages, priority handling for command sequencing, and execution behavior aligned with CIP requirements. The approach addresses communication patterns while preserving SRCI semantics for command execution, status reporting, and synchronization.

In addition, the paper provides categories of SRCI command support (e.g. core, extended, and optional functions) and explores how these categories can be represented via the CIP protocol for scalable adoption across ODVA compliant devices. PLC and robot controller interfacing models are discussed to illustrate how SRCI based command execution can be integrated into existing EtherNet/IP control architectures.

The expected outcome is a reusable, standards aligned framework that enables interoperable PLC to robot communication using CIP and EtherNet/IP. By providing CIP transports to support the SRCI standard and network data transmission the aim is to reduce integration complexity, promote multi-vendor compatibility, and provide a foundation for future enhancements in industrial robotics control within the ODVA ecosystem.

The transition of industrial automation toward Industry 4.0, autonomous mobile robots (AMRs), and flexible manufacturing requires robust wireless communication, such as Wi-Fi 6 and 5G. Traditional industrial Ethernet protocols were designed for wired, deterministic environments, and adapting them to wireless media introduces significant architectural challenges. This paper argues that EtherNet/IP™ demonstrates clear superiority for wireless deployments over PROFINET, EtherCAT, and Modbus/TCP. Built on the standard TCP/IP suite, EtherNet/IP integrates natively with wireless networks, avoiding the complex tunneling required by non-IP-based protocols. Through a series of Monte Carlo simulations (N=10,000 trials), this paper quantitatively demonstrates EtherNet/IP's advantages in latency (μ=8 ms), infinite node scalability, topology resilience (μ=109 ms recovery), and functional safety jitter tolerance. Furthermore, economic modeling reveals that wireless EtherNet/IP deployments can reduce 5-year Total Cost of Ownership (TCO) by up to 93% compared to wired alternatives, primarily by eliminating cable-fault downtime. These combined technical and economic strengths establish EtherNet/IP as the premier choice for robust, large-scale wireless industrial systems.
