Ethernet APL, advanced physical layer, moves closer to reality with this ODVA announcement of the availability of conformance testing for EtherNet/IP network-enabled devices that communicate over the Ethernet-APL physical layer. 

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.

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 1,000 meters (IEC 61158). Ethernet-APL devices adhere to IEC TS 60079-47 (2-Wire Intrinsically Safe Ethernet) in order to ensure “intrinsically safe” ignition protection.
