Bachmann SWI205 Industrial Ethernet Switch

Configured for deterministic data routing in industrial control architectures, the Bachmann SWI205 (SWI205) Industrial Ethernet Switch provides direct physical execution of packet switching for networked automation peripherals.

Hardware Specifications

Industrial Control & Network Determinism

• Profinet / EtherNet/IP Deterministic Networks: The switch is engineered to support industrial Ethernet protocols requiring strict frame timing. It maintains low jitter and minimizes latency to ensure that cyclic I/O data packets remain within the deterministic time windows required by PLC-based motion and control loops.
• Backplane Bus Communication Velocity Licences: The device architecture facilitates high-speed data propagation compatible with high-velocity backplane communication requirements, preventing bottlenecks when bridging local control network segments to supervisory Ethernet backbones.
• I/O Density Scaling: The switch port configuration supports the aggregation of high-density I/O node traffic, allowing for scalable network topologies where localized traffic remains segmented, thereby optimizing overall system bus utilization.
• Firmware Flash Compatibility: The device supports field-upgradable firmware to maintain compatibility with updated industrial communication stacks and network security patches, ensuring long-term interoperability within evolving automation infrastructures.

Frequently Asked Questions

Q: Does the SWI205 support IGMP snooping for multicast traffic management?

A: Yes, the switch hardware is capable of filtering multicast traffic, which is required to prevent packet flooding on industrial control networks utilizing EtherNet/IP or similar protocols.

Q: Is this switch capable of handling VLAN tagging (IEEE 802.1Q)?

A: Yes, the device supports VLAN tag awareness, allowing network administrators to segment traffic between different control applications and management networks to enhance system security and performance.

Field Installation Guidelines

• Mounting: Mount the unit on a standard 35 mm DIN rail. Ensure adequate clearance (minimum 50 mm) above and below the device to facilitate convective airflow and heat dissipation, particularly when operating near the upper limit of the temperature range.
• Shielding: Use S/FTP or F/UTP shielded Ethernet cabling. Ensure the cable shields are correctly terminated at the RJ45 connector housing to provide a continuous path for discharging electrostatic potential to the switch chassis ground.
• Grounding: Connect the chassis ground terminal to the main cabinet ground bus using a short, low-impedance conductor. Proper grounding is necessary to maintain the integrity of the integrated surge protection and EMI suppression circuits.
