Beacon Redundancy Protocol (BRP) Explained – IEC 62439-5 Guide

High availability is a mandatory requirement in modern industrial automation networks. Process control, power systems, water treatment plants, and safety-critical infrastructures cannot tolerate long communication interruptions. Beacon Redundancy Protocol (BRP) is an Ethernet-based redundancy protocol standardized in IEC 62439-5. It provides deterministic fault detection and fast recovery against single point failures while keeping the network architecture simple and… Read More »

Media Redundancy Protocol (MRP) Explained for Industrial Communication Networks

Industrial communication networks are very different from office or IT networks. In factories, substations, water plants, and process industries, communication is part of the control system itself. If data stops flowing, machines can stop, processes can become unstable, alarms may be delayed, and safety can be affected. Because of this, industrial networks must be highly available, predictable, and… Read More »

Rapid Spanning Tree Protocol (RSTP) in Industrial Ethernet Networks Explained

Industrial Ethernet networks form the backbone of modern SCADA, substation automation, manufacturing, and process control systems. Unlike traditional office IT networks, industrial networks must provide high availability, predictable behavior, and fast recovery from failures. Even short communication interruptions can lead to production losses, control instability, or safety risks. To meet these requirements, redundancy is commonly built into industrial… Read More »

PRP vs HSR Explained: IEC 62439-3 Complete Guide to Redundant Industrial Networks

Industrial networks depend heavily on reliable and continuous communication. Protection devices, SCADA gateways, and automation controllers must exchange information with strict timing and without interruption. Even a brief communication loss can cause protective functions to misoperate or lose visibility of the grid. To avoid this, industrial networks rely on seamless Ethernet redundancy methods that guarantee zero-time recovery. The… Read More »

HSR (High-Availability Seamless Redundancy) in IEC 61850 Networks: Complete Technical Guide

High-Availability Seamless Redundancy, or HSR, is one of the most advanced real-time redundancy mechanisms in industrial communication. It is mostly used in IEC 61850 digital substations, protection and control systems, and process bus networks where communication cannot stop even for a fraction of a second. HSR ensures zero-time recovery, meaning communication continues without interruption even during link or… Read More »

Parallel Redundancy Protocol (PRP): Complete Guide to Zero-Downtime Industrial Network Reliability

Parallel Redundancy Protocol (PRP) is a method used in industrial networks to make sure communication never stops—literally never. Many systems around us depend on constant data flow to stay safe and reliable. Think of power substations, industrial robots, trains, chemical plants, and automated production lines. If the network drops even one message, things can go wrong or shut… Read More »
