Maintaining data integrity and the highest system availability are mission-critical objectives for electrical substations. Because their automation systems require zero recovery time redundancy to achieve uninterrupted power supply to end-users, RedBoxes (redundancy boxes) are installed so that network data can be transmitted by two independent active paths simultaneously between systems and distributed devices.
Moxa, an innovation leader in the Industrial Internet of Things (IIoT), today introduced its PT-G503-PHR-PTP series of RedBoxes compliant with the new IEC 62439-3 Clause 4 (PRP) and Clause 5 (HSR) standards, thus guaranteeing network security, scalability and interoperability in substations automation networks, today and tomorrow. In addition to supporting Gigabit, these all-in-one devices are the world's first to support Coupling and QuadBox redundant protocols, helping engineers deploy zero (0 ms) switch-over time networks that are more versatile and efficient with faster error detection. Each box comes with three 10/100/1000BaseT(X) and 100/1000BaseSFP slot combo ports, along with a built-in MMS server, based on IEC 61850-90-4 switch modeling for power SCADA.
"Ethernet-based substation networks where devices are connected to switches and routers present the risk of communication latency due to network topology changes, traffic congestion, or packet queue prioritization. For mission-critical or time-sensitive applications, even millisecond long network interruptions cannot be tolerated, as they may severely impact system operation or jeopardize onsite personnel safety," explained Jim Toepper, Moxa's Business Development Manager for the Power Market.. "Our new RedBoxes establish efficient and effective management for a PRP/HSR Substation Automation Network where redundant network status can be fully monitored, and a single-point failure can be immediately discovered."
In addition to the PT-G503-PHR-PTP RedBox, Moxa is also launching the DA-820 rackmount embedded computer, the world's first native PRP/HSR management server. With the PT-G503 RedBox and DA-820 native PRP/HSR management server, Moxa's PRP/HSR substation solutions can help users collect, analyze, and integrate raw data from various devices on one single management platform, enabling efficient and visualized PRP/HSR network management, and making network diagnosis, troubleshooting, and device condition monitoring easier than ever.
