Eight ITP ports, eight digital inputs and managed redundancy functions for industrial Ethernet line and ring networks.
Siemens 6GK1105-3AA10 is the SIMATIC NET Industrial Ethernet ESM ITP80 electrical switch module for managed plant networks. The official OSM/ESM manual identifies eight 10/100 Mbit/s ITP ports using 9-pin Sub-D sockets, eight 24 V DC digital inputs, redundant 24 V DC supply connections, a signaling contact and an integrated redundancy manager. Network management supports monitoring of input states and configured event reporting. Procurement should verify the complete suffix, ITP cabling, port assignments, redundant ring or line structure, digital-input wiring, supply arrangement, management configuration, firmware and mounting position. Newer SCALANCE devices must not be treated as direct replacements without a network redesign review.

| Application | Engineering Relevance |
|---|---|
| Industrial Ethernet segment switching | Connects up to eight terminals or network segments through ITP interfaces. |
| Redundant line and ring networks | Ports 7 and 8 can couple further ESM units; redundancy planning must follow the installed topology. |
| Digital status monitoring | Eight 24 V DC inputs can be monitored through network management functions. |
| Legacy OSM/ESM maintenance | Supports exact-spare review where existing cabling, connectors and management settings must be preserved. |
The reviewed Siemens OSM/ESM manual confirms the exact order code and technical architecture but does not provide a current lifecycle label for 6GK1105-3AA10. No lifecycle status is assigned here. Siemens replacement guidance treats migration from OSM/ESM to SCALANCE X as application-dependent rather than a direct substitution. Review interfaces, topology, management features, media type, environmental requirements and project changes before planning migration.
6GK1105-3AA10 identifies the Siemens SIMATIC NET ESM ITP80 electrical switch module with eight ITP ports and digital inputs.
A current exact lifecycle label was not available in the official documents reviewed, so this page does not classify the module as Active or Discontinued.
Verify all 9-pin Sub-D ITP ports, the standby synchronization port, terminal blocks, signaling contact and digital-input connections.
The official manual documents an integrated redundancy manager and ring structures. The installed topology and configuration must be reviewed before replacement.
Not automatically. Siemens migration guidance requires an application-specific comparison of interfaces, topology and management functions.
Yes. Available inspection evidence can include the complete housing, readable nameplate, connectors, terminal blocks and packaging condition.
