The DA-PRP-HSR expansion module is compliant with IEC 62439-3 Clause 4 (PRP) and IEC 62439-3 Clause 5 (HSR) to ensure the highest system availability and data integrity for mission-critical applications that require redundancy and zero-time recovery.


With dual Gigabit Ethernet port design, the DA-PRP-HSR provides high performance for redundant network systems. In addition, the DA-PRPHSR features a built-in native PRP/HSR management middleware with MMS server that allows SCADA to collect IEC62439-3 registers from multiple devices for easy network diagnosis, troubleshooting, device management, and monitoring.


Moxa’s DA-820 series industrial computer with the DA-PRP/HSR is the ideal solution for power substation automation and process automation systems.

Enabling Efficient and Visually Represented PRP/HSR Network Management


native PRP HSR computerCreating a network management interface of devices and systems using different protocols can create risks and management issues that compromise effectiveness and security for substation automation networks. An efficient and visually represented PRP/HSR network using power SCADA with specially designed management middleware can effectively avoid these problems........more




Building the Industrial Cloud:The Immediate Future of M2M Technology


Building the Industrial Cloud:The Immediate Future of M2M TechnologyIn 2013, substantial steps towards building the Internet of Things at last began to materialize. In this white paper, Moxa examines the sorts of technology industrial networks will be relying on as they begin to build and deploy machine-to-machine networks. Software automations, hardware optimizations, and integrated platforms that fully exploit the convergence of these two main branches of system design are examined closely, to give IA and IT engineers a better idea of what challenges and obstacles they should be preparing for at the dawn of this new technological epoch........more

Making Smart Substations Even Smarter: Enhancing Substation Reliability, Availability, and Maintainability

Smart Substation Computer White PaperThis paper sketches out a few of the more important concerns that electricity suppliers should account for when planning substation upgrades. The focus is on how best to increase the reliability, availability, and maintainability of power substation automation networks within the context of the IEC 61850 vision, to give electricity suppliers a clear idea of the design procedures, device tolerances, and hardware and software features they should expect from the engineers and manufacturers who design and build their networking and computing devices.......more

Using MMS and SNMP to Integrate IT Management for Substation Automation

Using MMS and SNMP to Integrate IT Management for Substation AutomationThe devices that electrical substation automation systems are built from depend on highly precise, time-critical communications. Substation thus often use highly specialized monitoring systems to tackle this problem, but can approach it using different technologies. The most up-to-date, “smart” substations use the Manufacturing Messaging Specification (MMS) for communications among IEC 61850 intelligent electronic devices (IEDs), allowing SCADA to monitor and control IED states as well as process switchgear and transformer data directly. However, IT networking devices have been increasingly applied in IEC 61850 systems, and this equipment communicates using SNMP. Consequently, in the modern substation automation industry it’s clear that, for the time being, SNMP and MMS will continue to exist side-by-side. For designers and integrators of electrical substation equipment, bringing both MMS and SNMP support to IT equipment is an ideal, one-size fits-all alternative that allows for the greatest flexibility and adaptability around........more
