Industrial networks. Ethernet-APL port profile / Ethernet-SPE profile specification
1 Scope This document 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. The following technical features are part of this document:
topology with trunk and spur installation capability; 2-wire technology (full-duplex communication data rate of 10 Mbit/s); long distance (refers to cable lengths of several hundred meters, with spans up to 1 000 m); intrinsic safety (installation of Ethernet-capable field devices in hazardous areas);
