The Siemens SIMATIC NET OSM TP22 (6GK1105-2AE00) is an industrial-grade optical switch module designed to provide high-availability connectivity for Ethernet-based automation networks. Engineered for reliability in demanding environments, this module serves as a critical node for managing network redundancy and ensuring deterministic data transmission across distributed control systems.

Features

• Redundancy Management: Integrated Redundancy Manager (RM) functionality allows for rapid, sub-millisecond reconfiguration of ring topologies to prevent network downtime during link failures.
• Hybrid Connectivity: Equipped with two 100 Mbit/s fiber-optic ports for long-distance, EMI-immune backbone links and two 10/100 Mbit/s RJ45 ports for local device connection.
• Diagnostic Capabilities: Features four digital inputs for monitoring field-level binary signals and an integrated signaling relay contact for hardware-level fault notification.
• Redundant Power Design: Supports dual 24 VDC power inputs with automatic load transfer, ensuring continuous operation even in the event of a single power rail failure.

Applications

This module is widely utilized in sectors requiring robust network infrastructure, including petrochemical processing, power generation facilities, and large-scale mining operations. It is suitable for connecting PLCs, HMIs, and other industrial controllers in topologies where network stability and zero-loss communication are mission-critical.

Technical Specifications

Installation Guidelines

• Mounting: Ensure the module is mounted in a clean, dry environment with adequate clearance for ventilation to maintain operating temperatures within the 0 to 60 deg C range.
• Power Wiring: Connect both redundant 24 VDC power sources to the provided terminal blocks to utilize the module's automatic failover capability.
• Grounding: Always follow standard industrial grounding practices to protect the module from voltage surges and electromagnetic interference.
• Handling: Use ESD-safe handling procedures when working with the module to prevent damage to internal sensitive components.
• Cabling: Use high-quality multi-mode fiber patch cables for the optical ports and shielded twisted-pair (STP) Ethernet cables for the RJ45 interfaces to ensure signal integrity in high-EMI industrial zones.

FAQ

Does this module support ring redundancy?

Yes, the OSM TP22 features an integrated Redundancy Manager that monitors ring topologies and provides rapid reconfiguration if a link is lost.

Can I power this module using two separate power supplies?

Yes, the module is designed with dual power inputs to support redundant 24 VDC power configurations, allowing for seamless switching if one supply fails.
