Reliable Network Connectivity for Automation
This industrial switch connects multiple Ethernet devices within your control network. The Siemens 6GK1104-0AA00 provides four 10/100 Mbit/s RJ45 ports for seamless communication. It operates reliably in harsh factory environments from 0°C to 60°C. A metal housing protects the internal electronics from mechanical stress. Consequently, this switch ensures stable data exchange between PLCs, HMIs, and drives.
Port Configuration & Network Management
The Siemens 6GK1104-0AA00 functions as an unmanaged plug‑and‑play switch. You simply connect your devices and power up the unit. Each port automatically detects the correct link speed and duplex mode. The switch supports auto‑MDI/X on all four ports. Therefore, you can use straight‑through or crossover cables without any configuration.

Installation & Field Wiring
You mount the Siemens 6GK1104-0AA00 onto a standard DIN rail in your control cabinet. Connect the 24V DC supply to the two terminal blocks on the top. Then plug your Ethernet cables into any available RJ45 port. The green link LED illuminates when the switch detects a valid connection. Yellow LEDs flash to indicate active data transmission on each port.
Operational Advantages & Reliability
This unmanaged switch requires no software configuration or IP addressing. You simply install it and forget about maintenance for years. The metal housing withstands vibration and electromagnetic interference in industrial settings. The switch also supports store‑and‑forward switching to reduce network errors. Therefore, this Siemens switch provides a cost‑effective solution for small automation networks.
