Industrial Ethernet switch with eight 10/100 Mbit/s ITP Sub-D ports, digital inputs and network diagnostics

ITP topology check: Map all eight ITP ports, confirm whether ports 7 and 8 form a bus or ring coupling, record the redundant 24 V supply, digital-input assignments, alarm contact and management configuration, and verify legacy connector availability before replacement.

The ESM ITP80 connects up to eight devices or network segments through shielded ITP Sub-D9 ports. Ports 7 and 8 can couple additional modules for bus or ring structures, while digital inputs, LEDs, a signaling contact and management diagnostics support plant monitoring.

Network Design

A complete ITP port map and coupling plan prevents ring or bus faults when the switch is serviced.

Port inventory

Record the connected device, cable route, link speed and expected traffic for each of the eight ITP ports.

Coupling role

Document how ports 7 and 8 connect further ESMs and whether the installation uses a bus or ring structure.

Alarm signals

Label all eight digital inputs and the signaling contact and record how alarms are reported to the control system.

Description

6GK1105-3AA10 is the SIMATIC NET ESM ITP80 for legacy Industrial Ethernet installations using 9-pin ITP Sub-D connections. It supports eight autonegotiating 10/100 Mbit/s ports in an IP20 metal enclosure.

Before servicing 6GK1105-3AA10, label each network segment and digital input and save the available management settings. Restore power, local links and alarm behavior first, then reconnect any ring or parallel path under controlled monitoring.

Fault Isolation

Separate supply, physical-link, topology and management checks before replacing the complete switch.

Supply check

Measure both 24 V feeds and inspect the signaling contact before disconnecting network segments.

Link evidence

Record port LEDs and management information, then test the affected ITP cable and connector without moving every link.

Reset control

Use the Select/Set factory reset only after configuration evidence is saved and a restoration method is available.

FAQ

How can I confirm that 6GK1105-3AA10 fits the existing ITP network?

Verify the exact ESM ITP80 article, eight Sub-D9 ITP connections, 10/100 Mbit/s links, 24 V supply, cabinet space and use of ports 7 and 8. Preserve the full port and digital-input map.

How should ports 7 and 8 on 6GK1105-3AA10 be handled during replacement?

Treat them as possible coupling links to further ESM modules. Document the current bus or ring topology and link state, keep parallel paths controlled during startup and confirm stable communication before closing the final coupling path.

What installation checks are required for 6GK1105-3AA10?

Confirm IP20 cabinet protection, mounting space, protective grounding, both 24 V DC inputs, ITP connector retention and separation of communication cables from interference sources. Label every cable before removal.

How can intermittent network faults on 6GK1105-3AA10 be diagnosed?

Check supply stability, port LEDs, signaling contact, digital-input events and available management records. Inspect the affected Sub-D connector, ITP cable and shield, then determine whether the fault follows a port, cable or device.

When should the factory reset be used on 6GK1105-3AA10?

Use the Select/Set reset only when the approved procedure calls for it and the current settings have been documented. A reset can remove configuration needed for management, alarms or topology, so prepare the restoration steps first.

Can 6GK1105-3AA10 be replaced directly by a modern RJ45 switch?

Do not assume a direct replacement. Review ITP-to-RJ45 cabling, ring behavior, digital inputs, alarm contact, management functions, cabinet mechanics, grounding and the complete topology before engineering a migration.
