Ethernet-APL Specifications

Ethernet-APL Specifications

FieldComm Group, OPC Foundation, ODVA and PROFIBUS & PROFINET International are the  co-owners of the Ethernet-APL specification. FieldComm Group develops and maintains the FDI Specifications in its working group structure, establishing and controlling new technology developments and enhancements that support the needs of the process automation industry. FieldComm Group manages the Ethernet-APL Specifications and other related documents and provides related services and applications to end users.

      The Ethernet-APL Port Profile Specification version defines the ports which are the fundamental connections of Ethernet-APL products and provides the necessary industrial automation extensions to realize a standardized and interoperable IEEE 802.3cg network. This specification provides the fundamentals for connection points between field devices and switches.

        The Ethernet-APL EMC Test Specification defines the tests that ensure consistent EMC immunity and emissions of products with at least one port built to the Ethernet-APL Port Profile Specification.

        The Ethernet-APL Data Test Specification is designed to determine conformance to specifications defined in the IEEE STD. 802.3cg-2019 Standard for 10BASE-T1L as implemented in an Ethernet–APL Device. These tests include evaluation of the functionality of the PMA, PCS, PHY Control, and Auto-Negotiation sublayer of their 10BASE-T1L products.

        FieldComm Group assesses products for overall conformance. The tests in this test plan address those aspects of an Ethernet–APL Device that may impact the compliance of the underlying silicon, and/or, are deemed essential to validate in the final Ethernet–APL Device.

        The Ethernet-APL Power Test Specification defines the tests that ensure consistent implementation of at least one Ethernet-APL Port Profile as defined in the Ethernet-APL Port Profile Specification. The claimed Port Profile implementation is confirmed against the requirements of the Specification and multiple ports can be combined in a single product. The Power tests include noise, power, and other electrical characteristics of the Ethernet-APL port. Power tests do not include the full Intrinsic Safety suite therefore intrinsically safe products must submit to the appropriate approvals agency for IS certification marks. Completion of the Power testing depends on successful IS certification and EMC Testing. The Power test suite is completed in conjunction with the Data Test suite in overall testing of products.

          Defined strictly as a physical layer, Ethernet-APL supports any Ethernet–based protocol including those with real-time capabilities. The Ethernet-APL Engineering Guideline provides guidance for users and preparation for deployment of Ethernet-APL networks.
