PRP and HSR are the newest standardized redundancy protocols for industrial automation networks where zero recovery time is needed. These protocols are suitable for electrical substation automation or mission-critical applications that cannot tolerate any system downtime. Moxa’s integrated PRP/HSR technology provides the following benefits: • Full compliance with the latest international IEC 62439-3 standard for highest stability and interoperability • PRP and HSR in a single box to give you a choice for improving reliability • 100/1000 Mbps transmission speed across a combination of PRP/ HSR/InterLink ports • Support for hardware-based IEEE 1588v2 PTP IEC 61850-90-4 Modeling Switch for Power SCADA Moxa’s PowerTrans PT-7528 substation Ethernet switches come with fully integrated MMS support. PT-7528 IEC 61850-90-4 switches give substation engineers the option of bringing their IT devices into the same SCADA overview as the IEDs, or any other IEC 61850 device that uses MMS as its device-to-device messaging model. Substation Configuration Wizard Because substations are such a specialized environment, IT setups will only require a few key features. Thus, simplifying and streamlining the configuration process makes a lot of sense: by reducing the Fiber Check™: A Fiber Digital Diagnostic Monitoring (DDM) Tool Using Fiber Check™, a fiber Digital Diagnostic Monitoring (DDM) tool, Moxa’s IEC 61850 certified substation switches can monitor ST/SC (as well as SFP) connectors, and notify power SCADA systems via SNMP trap or MMS when abnormalities are detected, allowing operators to initiate maintenance procedures. Fiber Check™ reports and alarms may be communicated via web, CLI, or serial console; via MMS reporting or SNMP traps; by a digital relay; or in the system log. Preferably, several methods will be used to provide redundancy. This arrangement further allows system operators real time monitoring of things like transmission and reception power, temperature, and voltage/current along optical fiber connections. • Fiber status monitoring: Fiber temperature, working voltage, Tx/Rx power • Auto-warning: SNMP trap, relay, email, MMS, event log Noise Guard™: Wire-Speed Zero Packet Loss Technology To meet IEEE 1613 Class 2 requirements, network devices must have a level 4 EMC rating to guarantee that they will reliably tolerate high EMI conditions. • Mechanical Design: Integrated housing for better conduction • Customized Component: Newly redesigned fiber transceiver • Enhanced Power Supply Unit: Optimized circuit design, upgraded components IEC 61850 QoS Substation automation devices must communicate critical, low-level IEC 61850 multicasts (GOOSE/SMV) with the highest priority, without fail. Prioritizing the transmission of GOOSE/SMV packets guarantees that these messages are clearly received without distortion throughout the entire network, regardless of what other communications may be currently congesting the lines. Ping-based solutions are not sufficient to achieve this. To fully satisfy IEEE 1613 Class 2 requirements, substation switches must support strong QoS traffic shaping. • Communications packets may be assigned different priorities, depending on their importance • Packet types: GOOSE, SMV, PTP • Packet priorities: High, medium, normal, low Minimize Error Probability Detect Errors Faster Optimize Error Repairability configuration interface to only the relevant network features, setup and maintenance becomes much more efficient. Using Moxa’s browser- based configuration wizard, effectively deploying one of our network devices can take as few as 7 steps.
