Siemens extends Ruggedcom portfolio with a PRP/HSR module for enhanced reliability of industrial networks


  • Seamless redundancy and high precision time synchronization from a single device
  • Easy migration to highly reliable networks with zero packet loss
  • Minimal downtime and reduced risk of communication disruptions
  • Specifically designed for modern digital substation applications

Siemens has introduced a new line module for the Ruggedcom RST2228 and RST2228P Layer 2 19” rack switches, the Ruggedcom RMM2972-2RNA. This module strengthens the Ruggedcom RST2228 19” rack switch offering to the electric power utilities by providing seamless redundancy with PRP/HSR (Parallel Redundancy Protocol/High-availability Seamless Redundancy), enhanced IEEE1588 implementation, high bandwidth uplinks, and traffic filtering and segmentation from a single device. This module eliminates network downtime due to single points of fault, resulting in high reliability and availability for modern digital substation applications as mandated by the IEC 61850 standard.
