From generation to distribution of electric power!

How does rugged communication for mission-critical applications contribute to the reliable and economical flow of power – and that in a changing power landscape?

Siemens brings you the world’s most reliable communication solutions for any electrical power installation, field-proven to last for decades. Our portfolio offers unrivaled performance for power generation, transmission, distribution, substation automation, and any other function integrated in the electric power chain.

Our redundant network designs based on IEC 62439-3 ensure maximized availability of your applications. Full compliance with IEC 61850-3 and IEEE 1613 and continuous operation from -40 °C to +85 °C, ensure that our products can be used in the harshest environments.

Products developed in accordance with IEEE 1588 fulfill very demanding time-critical process bus requirements and our cybersecurity solutions are in compliance with NERC CIP.

An extensive range of products and a modular design featuring diverse interfaces provide the highest level of flexibility for any network architecture. Moreover, technical protection solutions against all kinds of data loss help you increase the availability of your plant.

Rugged communication can be that smart.

Guide to Understanding and Managing Situational Awareness Across the Energy Enterprise

Along with other technology vendors, Siemens worked closely with the National Cybersecurity Center of Excellence (NCCoE) at the National Institute of Standards and Technology (NIST) to address the energy sector's most pressing cybersecurity challenges. The collaborative group developed an example solution that explores the methods utilities can use to more readily detect and remediate anomalous conditions, investigate the chain of events that led to the anomalies, and share findings with other energy companies.

This practice guide shows how companies can reduce their risk and control physical and logical access to resources across the energy sector using standards, best practices, and commercially available products in a step-by-step format. View the Guide

Substation Automation

In transformer substations and substations in the high- and medium-voltage range the environmental conditions are often very harsh. To enable reliable operation of mission-critical applications, Siemens offers comprehensive Ethernet networking solutions that satisfy even the toughest requirements for strong EMC, antishock and antivibration – at operating temperatures between minus 40 °C and plus 85 °C. The state-of-the-art redundancy, diagnosis and remote access mechanisms further contribute to a smooth consistent operation. Using serial interfaces you can also easily integrate existing plant selections into the new network infrastructure.


  • Compact devices and network components with high port density (up to 28 gigabit ports)

  • Large number of electrical and optical interfaces

  • Data rates of up to 1 gigabit

  • Robust network architecture for extremely harsh environmental conditions

Time to Switch - Rugged communications for the Digital Substation

Digitalization ushers in a new day for the electric power industry around the world. The digital substation lies at the cornerstone of the evolving digital utility. It is the heart of an infrastructure that must be able to withstand the ever growing amount of data that will be generated and consumed by digital substation equipment in the coming years. To achieve this, operators must streamline the information and data exchanges in the electrical grid and supporting communication networks.

The new rugged Ethernet switches from Siemens are key additions to the essential building blocks of a digital substation network.  With the RUGGEDCOM RST2228, RSG909R and RSG907R Ethernet switches, you’ll be ready.
