More Information

Overview Manuals IRT Ports Ring Install

Features:

  • Four RJ45 ports carry 10/100 Mbit/s industrial Ethernet connections.
  • PROFINET IRT schedules deterministic cyclic traffic for time-critical devices.
  • Redundant power, a signaling contact, MRP, and optional C-PLUG support managed operation.
Siemens 6GK5204-0BA00-2BF2 keeps all field connections accessible on the front of its flat enclosure.

The IRT scheduler of 6GK5204-0BA00-2BF2 coordinates cyclic communication separately from ordinary Ethernet traffic.

Fault signaling and web diagnostics on 6GK5204-0BA00-2BF2 expose power, port, and network conditions to maintenance personnel.

The Siemens 6GK5204-0BA00-2BF2 is the XF204IRT article; ordinary XF204 variants do not provide the same IRT function.

Isochronous Real-Time Switching

  • Scheduled cycle: IRT reserves transmission windows for configured cyclic PROFINET traffic.
  • Port timing: All four RJ45 ports participate in the engineered real-time domain.
  • Class C role: The switch provides the documented PROFINET real-time class for motion traffic.
  • Configuration: The engineering project must match the physical port and topology assignment.

Front-Accessible Connections

  • Ethernet: Four RJ45 sockets face the cabinet access side.
  • Power: The redundant 24 V DC terminal remains separate from Ethernet.
  • Fault contact: A dedicated signaling terminal reports configured switch faults.
  • Set button: The front button supports the documented commissioning action.

Ring and Replacement Functions

  • MRP manager: The integrated manager coordinates the configured PROFINET ring.
  • Link recovery: Ring behavior depends on correct roles at every participating node.
  • C-PLUG: Optional media carries the saved switch configuration.
  • Power feeds: Two supply paths share the redundant input arrangement.

Mounting and Ambient Limits

  • DIN rail: The flat unit attaches to a 35 mm mounting rail.
  • Wall mounting: Direct wall mounting is supported by the documented hardware.
  • Orientation: Horizontal installation lowers the permitted upper temperature to 40 °C.
  • Enclosure: IP20 protection requires installation inside the appropriate cabinet.
Description
Siemens 6GK5204-0BA00-2BF2 is a flat SCALANCE XF204IRT managed industrial Ethernet switch for PROFINET networks with isochronous real-time traffic. Four RJ45 ports connect controllers, drives, and distributed devices at 10 or 100 Mbit/s while the switching hardware keeps cyclic IRT data within the configured schedule.

The front-facing connections of 6GK5204-0BA00-2BF2 place Ethernet, redundant 24 V DC supply, signaling contact, and the set button on the same accessible plane. This flat arrangement lets the switch sit in shallow installation spaces without routing cables through the rear of the enclosure.

Redundancy management inside 6GK5204-0BA00-2BF2 combines MRP operation with network management and PROFINET IO diagnostics. An optional C-PLUG can hold the configuration so the documented replacement procedure restores the switch parameters without rebuilding them port by port.

Operating limits for 6GK5204-0BA00-2BF2 apply to both the electronics and the mounting orientation. The redundant supply and fault contact remain separate from the four data ports, and horizontal installation reduces the permitted upper ambient temperature stated for normal mounting.

Technical notes
Front-facing connections let Siemens 6GK5204-0BA00-2BF2 combine four IRT-capable RJ45 paths with separate power and signaling terminals in a flat enclosure.

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 can 6GK5204-0BA00-2BF2 exchange standard Ethernet data while an IRT axis stays unavailable?
For 6GK5204-0BA00-2BF2, compare the PROFINET device name, topology, IRT domain, port assignment, cycle configuration, and the controller project.
What should be checked when the MRP ring through 6GK5204-0BA00-2BF2 does not recover?
Verify the 6GK5204-0BA00-2BF2 manager role, ring ports, cable order, device names, MRP domain, and that no second redundancy protocol controls the same loop.
Why can 6GK5204-0BA00-2BF2 overheat in a shallow cabinet?
Check the 6GK5204-0BA00-2BF2 orientation, clearance, airflow, supply load, and the 40 °C upper limit that applies to horizontal installation.
How should an optional C-PLUG be moved to a replacement 6GK5204-0BA00-2BF2?
Record the 6GK5204-0BA00-2BF2 state, isolate power, and follow the documented C-PLUG transfer and startup procedure before reconnecting the IRT network.
Why does the fault contact of 6GK5204-0BA00-2BF2 stay active although all four ports show link?
Review the 6GK5204-0BA00-2BF2 fault mask, redundant supply inputs, PROFINET diagnostics, ring state, and stored events because the contact can represent more than link loss.
What must match when replacing 6GK5204-0BA00-2BF2 with another XF204 unit?
Match the complete 6GK5204-0BA00-2BF2 order number, IRT capability, port count, firmware expectations, power terminals, and saved configuration rather than only the XF204 family name.
