Energy Storage and Power Consumption
The Siemens 6GK5104-2BB00-2AA3 draws 120 mA from the 24V DC supply. A small electrolytic capacitor provides 10 ms of ride-through during power dips. This storage prevents packet loss from brief voltage interruptions. The switch requires no external battery for operation.
Network Performance and Diagnostics
The switch forwards frames with a latency under 5 microseconds. It supports auto-MDI/MDI-X for straight or crossover cables. Users can connect this unit to PLCs, HMIs, and drives directly. This plug-and-play design requires no configuration for basic operation.
