The Siemens 6SL3520-0XE04-0AB0 is the PROFINET-enabled 4 kW variant in the SINAMICS G115D distributed drive family, carrying the XE04 catalog designation in the XE0x sub-series. This product fills a key gap from batch 17: XE04 was first confirmed with AF0 (AS-Interface); the AB0 (PROFINET) and AA0 (I/O Control) variants are now confirmed, completing all three communication interfaces at 4 kW in the XE0x sub-series.

XE04: the XE0x sub-series at 4 kW is now complete

XE04 — the 4 kW FSB fan-cooled code in the XE0x sub-series — now carries all three G115D communication variants: AA0 (I/O Control), AF0 (AS-Interface), and AB0 (PROFINET). This mirrors the complete comm coverage of its XE4x counterpart (XE44) and its 1XA counterparts (1XA04, 1XA24). The XE0x sub-series at 4 kW is fully characterized — no missing variants remain. XE04 is mechanically identical to XE44, XH24, XM04, XN04, 1XA04, and 1XA24 — the same 4 kW fan-cooled FSB hardware across seven parallel catalog codes.

PROFINET at 4 kW: the daisy-chain advantage

The AB0 variant integrates PROFINET IO, EtherNet/IP, and PROFIsafe on a single Ethernet interface. The 2-port switch enables daisy-chain topology — each drive passes the Ethernet frame to the next, eliminating star-wiring to a central switch. At 4 kW, the drive typically powers mid-length accumulation conveyors and transfer sections — not as numerous as the 0.55–1.5 kW zone drives but deployed in enough quantity that daisy-chaining reduces switch-port count meaningfully. PROFIsafe delivers STO at SIL3 on the same cable, eliminating the separate hardwired safety circuit.
