More Information

Overview Manuals Port Roles IRT Traffic Redundancy Configuration

Features:

  • Four RJ45 ports switch 10/100 Mbit/s Ethernet and deterministic PROFINET IRT frames.
  • Primary and redundant DC feeds power the switch while a separate contact reports faults.
  • Managed diagnostics and several ring functions support controlled industrial network recovery.
Traffic entering Siemens 6GK5204-0BA00-2BA3 is classified and forwarded through the same four-port hardware, while IRT scheduling protects deterministic exchanges.

The supply and alarm terminals of 6GK5204-0BA00-2BA3 remain outside the Ethernet path so loss of a feed can be reported to another device.

Management channels on 6GK5204-0BA00-2BA3 expose configuration, port status, error counters, time services, and redundancy state.

The Siemens 6GK5204-0BA00-2BA3 SCALANCE X204IRT Managed Ethernet Switch may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Ethernet and Alarm Connections

  • RJ45 group: Four copper ports connect industrial Ethernet network components and terminal devices.
  • Port speed: Each RJ45 connection negotiates 10 or 100 Mbit/s operation.
  • Alarm circuit: The two-pole contact transfers a configured switch fault to an external circuit.
  • Supply terminals: Separate primary and redundant terminals power the switch electronics.

Deterministic PROFINET Forwarding

  • IRT path: The switch schedules PROFINET IRT frames for deterministic transfer.
  • PROFINET device: The switch can appear as a PROFINET IO device for configuration and diagnostics.
  • Standard traffic: Non-IRT Ethernet frames share the physical ports under the switch forwarding rules.
  • Timing services: SNTP and SICLOCK functions support documented time-alignment needs.

Ring and Standby Functions

  • Ring manager: The switch can control the selected industrial Ethernet ring.
  • MRP role: Media Redundancy Protocol provides a standardized ring-recovery path.
  • Standby coupling: Standby functionality coordinates a redundant network coupling arrangement.
  • Passive listening: Passive listening observes redundancy traffic without taking the active manager role.

Management and Diagnostic Access

  • Local command path: CLI provides text-based switch configuration.
  • Browser path: Web management exposes configuration and status through HTTP or HTTPS.
  • Engineering path: STEP 7 configures the supported PROFINET and switch parameters.
  • Network monitor: SNMP versions 1, 2, and 3 expose supported diagnostic objects.
Description
Siemens 6GK5204-0BA00-2BA3 is a SCALANCE X204IRT managed industrial Ethernet switch with four 10/100 Mbit/s RJ45 ports. It forwards standard Ethernet and deterministic PROFINET IRT traffic while providing switch management and device diagnostics.

Primary and redundant 24 V DC terminals feed 6GK5204-0BA00-2BA3 across the same 18 to 32 V range. A separate two-pole signaling contact carries the configured fault state to an external monitoring circuit instead of mixing fault indication with network data.

Ring manager, redundancy manager, standby coupling, HSR, MRP, and passive-listening functions let 6GK5204-0BA00-2BA3 take different roles in an industrial redundancy design. The selected mode must match the surrounding topology because each function controls a different recovery path.

Configuration and diagnostics for 6GK5204-0BA00-2BA3 are available through CLI, web management, STEP 7, PROFINET IO, and SNMP. DIN rail, wall, S7-300 rail, and S7-1500 rail mounting place the IP30 enclosure inside the cabinet.

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.
What distinguishes IRT traffic on 6GK5204-0BA00-2BA3 from ordinary Ethernet?
Siemens 6GK5204-0BA00-2BA3 schedules PROFINET IRT frames for deterministic transfer while standard frames use normal switch forwarding.
Can 6GK5204-0BA00-2BA3 continue operating from one DC feed?
The 6GK5204-0BA00-2BA3 provides primary and redundant supply inputs, but wiring and fault signaling must match the intended redundancy plan.
How is a power or switch fault reported by 6GK5204-0BA00-2BA3?
Use the two-pole alarm contact of 6GK5204-0BA00-2BA3 for the external fault circuit and network diagnostics for detailed status.
Which ring function should be selected on 6GK5204-0BA00-2BA3?
Select the 6GK5204-0BA00-2BA3 ring manager, MRP, HSR, standby, or passive role that matches the existing network design.
Does 6GK5204-0BA00-2BA3 provide secure remote management?
Yes. The 6GK5204-0BA00-2BA3 data sheet lists HTTPS and SSH in addition to its standard management interfaces.
Why must 6GK5204-0BA00-2BA3 be installed inside a cabinet?
The 6GK5204-0BA00-2BA3 enclosure is IP30, so the installation must provide the additional environmental protection required on site.
