Abstract

IEC TS 63444:2023 is applicable to process automation equipment using a 10BASE-T1L compliant (see IEEE Std 802.3-2022, Clause 146) 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.The following technical features are part of this document:- topology with trunk/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);- power supply to field devices over the same 2-wire cable used for data communication.
