Thread-topic: Update on MT63444

All – Our comments to MT63444 on Draft Technical Presentation (DTS): IEC TS 63444 ED2: Industrial networks – Ethernet-APL port profile / Ethernet-SPE profile specification (65C/1386/DTS) , are in the process of being integrated into ED3 of the DTS. This morning, I attended the JWG Technical Team "Independent Protocol Physical Layer Group (10Base-T1L and extension 100Base-T1L)” hosted by Profi International. (this is a joint working group through the Ethernet APL project), building consensus for the IEC documents. The group accepted (or accepted with edits) most all our comments. The exception is they will consider whether to specify class 15 at < 40m on some wiring heavier than the 24 AWG currently in the draft rather than simply deleting the entry in table 17.
