ODVA has announced a series of enhancements to EtherNet/IP, expanding its capabilities to help meet the evolving needs of industrial automation. The updates focus on broader process device support, strengthened cybersecurity features, and foundational improvements that further reinforce interoperability and scalability across diverse system architectures.
Key updates to EtherNet/IP include:
Expanded process device profiles, now supporting:
RTD (Resistance Temperature Detector) sensors
Thermocouple temperature sensors
Level sensors
Concurrent connections with CIP Safety, enabling more flexible and fault-tolerant system architectures.
Support for PA-DIM version 1.1, improving data modeling and simplifying multi-vendor device integration.
A new device-based firewall introduced within CIP Security, offering improved threat protection.
A pull model for configuration in CIP Security, providing a more secure and controlled method of deployment.
These updates enhance EtherNet/IP’s ability to support process industries, where secure communication and broader sensor compatibility are vital.
“ODVA continues to demonstrate that it is rapidly evolving to keep its technologies, and the solutions that incorporate these technologies, and the end users and OEMs that deploy these technologies, at the forefront of the ever-changing market demands that require an endless demand for additional data and open connectivity solutions as well as tools to help with sustainability and operational resilience,” said Craig Resnick, Vice President at ARC Advisory Group. “EtherNet/IP is continuously evolving to meet the changing demands of the industrial market. This includes adapting to the requirements of process industries with expanded process device profiles, such as RTD and thermocouple temperature and level sensors, along with CIP Safety. EtherNet/IP's transformation also encompasses new security capabilities, including a device-based firewall and a pull model for configuration to CIP Security, as well as compliance with the EU Cybersecurity Resilience Act (CRA) and Machinery Safety Act. Technologies, such as IP version 6, which will soon be included in the EtherNet/IP Specification after updates are finalized and published, are crucial as IPv6 now constitutes almost half of all Internet traffic. With the increasing proliferation of IoT devices, sensors, and interconnected machinery on the OT floor, the demand for more address space is often growing faster than the infrastructure can keep up, making ODVA's announced enhancements even more critical to end users and OEMs.”
Looking ahead, ODVA is also progressing in several strategic technology areas:
Support for IPv6 in upcoming EtherNet/IP specifications, addressing the need for expanded address space due to the rapid growth of IoT.
CIP Energy building blocks to enable real-time energy monitoring, dynamic demand-response, and energy optimization—supporting sustainability and carbon neutrality goals.
Increased use of contextual metadata in device description files, improving offline configuration and real-time diagnostics.
Exploration of Bluetooth as a CIP-compatible interface for industrial use cases.
Alignment with global cybersecurity regulations, including enhancements in device identity management and secure communications.
These developments reinforce ODVA’s commitment to advancing more secure, interoperable, and future-ready industrial automation systems as industries move toward greater connectivity and resilience.
