Siemens 6GK5116-0BA00-2AA3 — 16-Port Unmanaged Industrial Ethernet Switch | SCALANCE X-100 Series
Engineering Background
Industrial automation networks demand deterministic communication, rugged hardware, and zero-configuration reliability at the field level. The Siemens SCALANCE X-100 series was engineered specifically for these environments — delivering plug-and-play Ethernet switching in the harshest industrial conditions without the overhead of managed network administration.
Product Positioning
The 6GK5116-0BA00-2AA3 is a 16-port unmanaged Fast Ethernet switch designed for PROFINET, PROFIBUS-over-Ethernet, and general industrial LAN topologies. It is the preferred choice for procurement engineers building cost-effective, high-reliability field-level networks in manufacturing, process automation, and machine-building applications.

- Siemens TIA Portal compatibility — recognized as a network node in STEP 7 and TIA Portal topology views
System Architecture & Signal Flow
The 6GK5116-0BA00-2AA3 operates as a transparent Layer 2 bridge. Incoming Ethernet frames are received on any RJ45 port, stored in the internal frame buffer, and forwarded to the destination port based on MAC address table lookup (4K MAC address capacity). The switch learns MAC addresses dynamically with a 300-second aging timer. All 16 ports share a non-blocking switching fabric at full wire speed, ensuring <10 µs port-to-port latency — critical for PROFINET RT (Real-Time) Class 1 compliance.
Power is supplied via the front-terminal 24 V DC connector. A fault relay output (floating contact) signals power loss or internal fault to the PLC or SCADA system, enabling automated alarm escalation without additional monitoring hardware.

Technical FAQ
Q: Is the 6GK5116-0BA00-2AA3 compatible with PROFINET IRT (Isochronous Real-Time)?
A: No. Unmanaged switches do not support IRT. For IRT topologies, use SCALANCE X-200 or X-300 managed switches with PROFINET IRT forwarding.
Q: Can I use this switch in a ring topology for redundancy?
A: No. Ring redundancy (MRP/HRP) requires a managed switch. This unit supports only star and line topologies.
Q: What is the maximum cable length per port?
A: 100 m per segment using Cat5e or Cat6 UTP/STP cable per IEEE 802.3 specification.
Q: Does the switch support PoE (Power over Ethernet)?
A: No. The 6GK5116-0BA00-2AA3 does not provide PoE. For PoE requirements, refer to the SCALANCE XP-200 series.
Q: Is a Siemens software license required?
A: No software license is required. The switch is fully operational out of the box with no configuration tools needed.
Q: What is the replacement / successor model?
A: The SCALANCE XB116 (6GK5116-0BA00-2AB2) is the current production successor with identical port count and improved diagnostics.
