Industrial networks - Ethernet-APL port profile / Ethernet-SPE profile specification
IEC TS 63444:2026 is applicable to process automation equipment using a 10BASE-T1L compliant Physical Layer (PHY). Ethernet-APL intrinsically safe profiles with different predefined entity or limitation parameters (for example voltage, current, power, capacitance, inductance, cable length) simplify the examination of the interconnection of different Ethernet-APL ports.
Furthermore, this document is also applicable to factory and building automation and control equipment using a 10BASE-T1L compliant, and Power over Data Lines (PoDL) compliant Physical Layer (PHY) for non-intrinsically safe Ethernet installations.
NOTE: In this document the term Ethernet-SPE is used for PoDL compliant PHY.
