Product Introduction
The Siemens 6GK5116-0BA00-2AA3 is a SCALANCE X116 unmanaged Industrial Ethernet switch intended for copper-based automation networks. Its 16 RJ45 ports support 10 and 100 Mbps Ethernet communication, allowing PLCs, operator stations, drives, remote I/O, controllers, and other Ethernet devices to be interconnected without requiring managed-switch configuration.
The important distinction is that this is an unmanaged X116, not a managed SCALANCE switch with configurable VLANs, routing, or network-management functions. The hardware provides basic Ethernet switching plus LED diagnostics, fault signaling, and redundant DC power input. Siemens documentation also lists the X116 within the SCALANCE X-100 operating-instruction family.

Engineering Pain Point
The usual replacement mistake is comparing only the number of Ethernet ports. A 16-port switch may have the same RJ45 count while using a different power arrangement, management architecture, port speed, temperature rating, or SCALANCE generation. For 6GK5116-0BA00-2AA3, the fact that it is an unmanaged 10/100 Mbps switch with redundant 24 VDC supply is part of the compatibility requirement.
Typical Applications
- PLC and DCS network segmentation where basic Ethernet switching is sufficient.
- Industrial control cabinets connecting multiple copper Ethernet nodes.
- Machine-level Industrial Ethernet networks with 10/100 Mbps equipment.
- Legacy automation networks where maintaining the existing SCALANCE hardware architecture is preferable to changing network behavior.
Technical Pitfalls to Avoid
- Do not confuse X116 with managed SCALANCE variants.
The X116 is specified as an unmanaged switch. Do not assume that a replacement provides VLAN, SNMP, redundancy-manager, or other managed-switch functions simply because it has the SCALANCE name. - Verify the exact MLFB.
6GK5116-0BA00-2AA3 identifies the . Siemens also lists the related X124 as 6GK5124-0BA00-2AA3, so similar numbering does not mean identical hardware. - Check the power wiring.
The unit accepts 24 VDC with an 18–32 VDC range and provides redundant voltage-supply connections. Confirm both supply paths and cabinet protection before replacement. - Do not overlook temperature and enclosure constraints.
The published operating range is -20 to +70°C and protection class is IP30. If the switch is installed in a hot cabinet, verify actual cabinet temperature rather than relying on the ambient plant temperature. - Check the fault-signaling circuit.
If the existing PLC or alarm system monitors the switch’s signaling contact, document its wiring before removal. Replacing the Ethernet switch without reconnecting this circuit can remove a useful network-health indication.

Procurement note: Specify the complete Siemens 6GK5116-0BA00-2AA3 / SCALANCE designation. Before substitution, verify the 16-port requirement, 10/100 Mbps copper network, unmanaged operating concept, redundant 24 VDC supply, fault-contact wiring, mounting method, and cabinet temperature. The Siemens MLFB should take precedence over generic descriptions such as “16-port Ethernet switch.”
