Description
The Siemens 6GK1104-0AA00 is an 8-port Industrial Ethernet fan-out unit, model type SSV104, designed for integration within Simatic Net infrastructure. This module is engineered to support legacy Simatic S5 automation networking by distributing centralized network nodes into eight discrete local terminal branches. By acting as an active signal hub, it facilitates multi-device transceiver drop connections, ensuring reliable communication routing in demanding industrial environments without signal degradation.
Features
- 8-port active configuration for Industrial Ethernet baseband networks.
- Provides independent signal amplification across each isolated drop channel.
- Robust metal chassis construction for enhanced shielding against electromagnetic interference (EMI).
- Deterministic transceiver collision resolution logic to maintain network integrity.
- Transparent hardware operation designed to offload signal management tasks from host PLC interface cards.
Applications
This unit is suited for high-availability industrial environments where legacy Ethernet baseband topologies are utilized. Typical applications include thermal power stations, petrochemical refining complexes, and heavy-duty mining automation systems where deterministic communication and fault isolation are required.

- Maintain proper grounding of the metal chassis to ensure effective EMI shielding in high-noise environments.
FAQ
What is the primary function of the 6GK1104-0AA00?
The unit acts as an active fan-out hub for Industrial Ethernet baseband networks, allowing a single network trunk to be split into eight independent drop lines for multi-device connectivity.
Is this unit compatible with modern PROFINET networks?
This module is specifically designed for legacy Simatic S5 Simatic Net infrastructure. It is intended for use with older baseband Ethernet topologies rather than modern switched PROFINET systems.
How does the unit handle network faults?
The module features isolated drop channels, which help prevent a physical failure or collision on a single node from collapsing the entire network backplane.
