Overview

SCALANCE X204RNA is designed for deployment in high-availability networks using HSR (High-availability Seamless Redundancy) or PRP (Parallel Redundancy Protocol) based on IEC 62439-3.

HSR Highlights

• Frame redundancy via dual-transmission in ring topologies
• No network reconfiguration needed after failure—seamless redundancy
• Connects non-HSR-capable devices to HSR networks
• Enables smooth transition between HSR and PRP systems

PRP Highlights

• Sends identical frames across two separate LANs
• Complete bumpless redundancy with no failover time
• Connects non-PRP-capable devices to redundant dual-network environments
