The 6SL3520-1XL01-1AF0 is the 1.1 kW, FSA-frame G115D in the 1XL variant with the AF-suffix PROFINET communication interface — the fieldbus-equipped entry point for decentralized automation in SIMATIC environments. Rated 3.1 A continuous with 6.2 A peak (200% for 3 seconds), it powers light-duty conveyor sections, diverters, and roller beds directly on the machine frame. The 1XL FSA enclosure (380 × 216 × 129 mm) is taller than the 1XK equivalent, accommodating additional integrated options while preserving the same width and depth.

The AF suffix integrates PROFINET and EtherNet/IP dual-port communication — the drive appears as a node on the automation network with full telemetry, diagnostics, and parameter access via TIA Portal. This eliminates the discrete I/O wiring and gateway modules that a base-variant (AA) or enhanced-I/O (AB) drive would require for networked control. Standard G115D features apply: integrated C2 EMC filter, internal braking chopper, STO SIL 2 via Profisafe, SAM web-server commissioning, and IP65/IP66 protection for washdown and dusty environments.
