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 »

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) 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 »
