It uses industrial ring technology with Ethernet Ring Protection Switching (ERPS) to create redundant communication paths between network devices. If a cable link or device fails, traffic can automatically switch to an available path to maintain connectivity and minimize network. In industrial automation and critical infrastructure, network downtime is not merely an inconvenience—it can result in massive financial losses and serious safety hazards. Studies reveal that manufacturing companies can lose over $300,000 per hour of downtime, with some estimates actually being two. Moxa provides a wide range of industrial Ethernet switches that feature industrial-grade reliability, network redundancy, strengthened security, easy management, and competitive price-to-performance ratios. 60W and 90W Power over Ethernet (PoE) options via PoE injectors. If one source fails, the other continues supplying power, keeping the device running without interruption. We offer toughened, industry-specific products with multiple industry certifications, such as parts of the EN 50155 standard for rail applications, IEC. Network redundancy in industrial control systems ensures continuous SCADA and DCS communication despite cable cuts, switch failures, or device faults. Common redundancy protocols include RSTP for general switching, MRP and DLR for ring topologies, HSR and PRP for zero-switchover hitless redundancy.
