More Information

Overview Manuals BusAdapter Paths Network Control Power & Alarms Mounting Limits

Features:

  • Two BusAdapter positions define the connector and transmission medium used by the managed switch.
  • Four 10/100 Mbit/s paths support switched Industrial Ethernet and PROFINET traffic.
  • Redundant DC inputs, a signaling contact, and port diagnostics expose supply and network conditions.
Siemens 6GK5204-2AA00-2YF2 separates the switch electronics from the removable media interfaces selected for each installation.

Frames entering 6GK5204-2AA00-2YF2 are forwarded through the configured electrical or optical BusAdapter paths.

Management and redundancy functions on 6GK5204-2AA00-2YF2 control topology recovery without changing the connected device protocol.

The Siemens 6GK5204-2AA00-2YF2 SCALANCE XF204-2BA DNA Managed Industrial Ethernet Y-Switch may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

Media Selection and Port Formation

  • Base unit: The switch electronics are supplied without a fitted network connector.
  • Adapter positions: Two BusAdapter slots determine the electrical or optical media available to the four switched paths.
  • Selection check: The adapter type, remote interface, cable, and link distance must describe the same medium.
  • Replacement scope: A base-unit exchange does not remove the need to verify both installed BusAdapters.

Managed Layer 2 Functions

  • Device identity: DCP assigns the PROFINET station parameters used by the engineering project.
  • Topology view: LLDP reports neighboring devices and the port relationship seen by management.
  • Ring recovery: HRP or MRP controls the documented alternate path after a ring link changes state.
  • Traffic review: Port statistics and mirroring expose packet activity without converting the switch into a router.

Redundant Supply and Fault Output

  • Dual feeds: Two 24 V DC inputs supply one switch and allow monitoring of each source path.
  • Signaling contact: The floating output passes a configured fault state to the cabinet control circuit.
  • Local indication: Front LEDs distinguish supply, device, and port conditions before detailed diagnostics are opened.
  • Input protection: The supply input includes the documented non-replaceable 2.5 A protection.

Cabinet and Environmental Boundaries

  • Rail mounting: The unit attaches to a 35 mm DIN rail rather than an S7 mounting rail.
  • Enclosure: IP20 construction requires installation inside a suitable industrial cabinet.
  • Temperature: The conformal-coated switch is specified for operation from -40 to 70 °C.
  • Humidity: Operation permits up to 95% relative humidity at 25 °C without condensation.
Description
Siemens 6GK5204-2AA00-2YF2 is a SCALANCE XF204-2BA DNA managed Industrial Ethernet Y-switch. Its base unit processes four 10/100 Mbit/s paths while two BusAdapter positions determine the physical network connections fitted to the switch.

Two redundant 24 V DC feeds power 6GK5204-2AA00-2YF2, and the floating signaling contact carries a configured supply, port, or device fault to cabinet monitoring. The removable C-PLUG can hold configuration data so the network settings remain tied to the selected storage medium.

Management on 6GK5204-2AA00-2YF2 is available through CLI, web access, SNMP, and STEP 7. DCP and LLDP identify the switch and its neighbors, while port statistics and PROFINET diagnostics separate a physical link problem from a configuration or traffic fault.

Installed on a 35 mm DIN rail, 6GK5204-2AA00-2YF2 supports HRP and MRP ring functions over the media provided by its BusAdapters. The base unit is delivered without those adapters, so connector type and transmission medium must be selected separately for the planned topology.

Technical notes
Siemens 6GK5204-2AA00-2YF2 requires the selected BusAdapters before its four managed Ethernet paths have physical network connectors.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does 6GK5204-2AA00-2YF2 have no fixed RJ45 port on the base unit?
Siemens 6GK5204-2AA00-2YF2 uses two BusAdapter positions, so the installed adapters determine the physical connector and medium.
What should be checked when a link stays down on 6GK5204-2AA00-2YF2?
Check the 6GK5204-2AA00-2YF2 BusAdapter type, cable medium, remote port, speed negotiation, connector seating, and port diagnostics.
Can 6GK5204-2AA00-2YF2 continue after one DC feed is lost?
A healthy redundant input can continue supplying 6GK5204-2AA00-2YF2, while the missing source can be reported by its diagnostics or signaling contact.
Why does an MRP ring on 6GK5204-2AA00-2YF2 fail to recover?
Verify the 6GK5204-2AA00-2YF2 ring ports, MRP role, partner configuration, closed physical loop, and diagnostic event sequence.
What must be retained before replacing 6GK5204-2AA00-2YF2?
Archive the 6GK5204-2AA00-2YF2 configuration and record both BusAdapters, power wiring, signaling contact, ring role, and connected ports.
Does 6GK5204-2AA00-2YF2 route between IP networks?
No. Siemens 6GK5204-2AA00-2YF2 is a managed Layer 2 switch; its PROFINET and redundancy functions do not provide IP routing.
