Call for Volunteers - Working Group Ethernet-APL Conformance



The Ethernet-APL technology is co-owned by FieldComm Group, ODVA, OPC Foundation, and PROFIBUS & PROFINET International (PI). The Ethernet-APL Joint Working Group, which operates within the PI structure, is tasked with developing and maintaining conformance tests for products built to Ethernet-APL requirements.  Ethernet-APL is the physical layer supported by protocols including EtherNet/IP, HART-IP, OPC UA/UAFX, and PROFINET to name a few. The organizations collaborate toward wider adoption of the Ethernet-APL standards, Test specifications, methodology, tools, and testcases that are essential to overall conformance.

Objectives are update Ethernet-APL conformance test specifications concerning the topics new features introduced with latest Ethernet-APL technical specifications, fix known test bugs, clarify and resolve support issues, and test coverage for all product types.

Participants need to have experience with implementing Ethernet-APL, Ethernet physical layers, intrinsic safety, and hardware development for a variety of industries, applications, and requirements.
