The communication of EtherNet/IP network-enabled devices via the physical layer Ethernet-APL for process automation can now be tested and confirmed: The user organisation ODVA announced at the SPS trade fair that conformance tests are now available.

Conformance testing verifies the Ethernet-APL physical layer functionality by checking that the different port types properly adhere to the relevant specifications. The EtherNet/IP communication network functionality is also confirmed as a part of this process. Together, both tests ensure maximum interoperability between vendors as well as different types of instruments and infrastructure components. “The availability of complete EtherNet/IP over Ethernet-APL conformance testing is the final step for ODVA to make the benefits of Ethernet available at the field level in the process industries,” said Dr. Al Beydoun, President and Executive Director of ODVA.

Ethernet-APL is the new intrinsically safe, two-wire Single Pair Ethernet (SPE) solution, based on an extension of 10BASE-T1L (IEEE 802.3cg2019) that meets the requirements of the process industries. The advantages of Ethernet-APL include significantly faster communication speeds of up to 10 Mbit/s, hazardous area protection, power to field instrumentation, and long cable runs of up to 1 km (IEC 61158). Ethernet-APL devices adhere to IEC TS 60079-47 (2-Wire Intrinsically Safe Ethernet) in order to ensure “intrinsically safe” ignition protection.

EtherNet/IP over Ethernet-APL conformance test orders are ready to be placed now. Vendors can place their test orders on ODVA’s website. The physical layer testing covers IEEE data, 10BASE-T1L, and Ethernet-APL port profiles power requirements. This includes EMC testing that aligns with IEC/EN 61326 and NAMUR NE 21. EtherNet/IP network conformance testing covers communication functions defined above layer 2 of the OSI model and relies upon ODVA’s standard process. Intrinsic safety and/or functional safety certification are taken care of by separate safety testing agencies. Vendors are now able to bring “ODVA Conformant” products for EtherNet/IP to the market that can function on the Ethernet-APL physical layer.

The Ethernet-APL physical layer transports application-layer safety and security services such as CIP Safety and CIP Security which utilize IEC 61508 and ISA/IEC 62443 standards. On the website www.odva.org the latest version of The EtherNet/IP Specification including EtherNet/IP for Ethernet-APL can be found.
