2-40 www. m oxa. com Introduction to IEC 61850-3 Ethernet Switches 2 Industry-Specific Ethernet Switches > Industry-Specific Ethernet Switches PT-7728-PTP Series The PowerTrans PT-7728-PTP switches are designed to meet the demands of power substation automation systems (IEC 61850-3, IEEE 1613). The PT-7728-PTP’s redundant ring, and dual isolated redundant power supplies increase the reliability of your communications and save on cabling/wiring costs. Moxa’s PT-7728-PTP IEC 61850-3 Ethernet switches support the latest version of IEEE 1588 technology (IEEE 1588v2 PTP) to fulfill precision time synchronization requirements for protection and control applications. These Ethernet switches guarantee time-stamping accuracy within 1 μs for the IEC 61850 process layer. They can be configured for 1588 v2 Master, Boundary Clock, and Transparent Clock functionality. • IPv6 Ready logo awarded (IPv6 Logo Committee certified) • DHCP Option 82 for IP address assignment with different policies • Modbus/TCP industrial Ethernet protocol supported • Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 switches), and RSTP/STP for network redundancy • PRP (Parallel Redundancy Protocol): Transmit or receive two independent active paths to/from different LANs simultaneously on a zero recovery time network. • HSR (High-availability Seamless Redundancy): Every frame is duplicated and then transmitted in both directions of the HSR ring for zero switchover time. • IGMP snooping and GMRP for filtering multicast traffic from industrial Ethernet protocols • IEEE 802.3ad, LACP for optimum bandwidth utilization • Bandwidth management prevents unpredictable network status • Multi-port mirroring for online debugging • IEEE 1588v2 PTP (Precision Time Protocol) with hardware time stamping for precise time synchronization of networks • Support for both IEEE 1588 Boundary Clock and Transparent Clock IEC 61850-3 Layer 2 IEEE 1588v2 PTP rackmount (PRP/HSR) Ethernet switches When used with specific PM-7200 PRP/HSR series modules, the PT- 7728-PTP series switches are compliant with the latest standardized redundancy protocols for industrial automation networks. IEC 62439-3 Clause 4 (Parallel Redundancy Protocol, PRP) and IEC 62439-3 Clause 5 (High-availability Seamless Redundancy, HSR) ensure the highest system availability and data integrity for mission-critical applications in electrical substations and/or process automation systems that require zero recovery time redundancy. The modular design of the PT-7728-PTP also makes network planning easy, and allows greater flexibility by letting you install up to 14 IEEE 1588 Fast Ethernet ports or up to 24 non-IEEE 1588 Ethernet ports and 4 Gigabit (PRP/HSR)*ports. Along with a choice of either front or rear wiring, these features together make the PT-7728-PTP suitable for a variety of industrial applications. * Only available with PM-7200 PRP/HSR series module • Automatic warning by exception through email, relay output • RMON for efficient network monitoring and proactive capability • Automatic recovery of connected device’s IP addresses • Line-swap fast recovery • Configurable by Web browser, Telnet/Serial console, CLI, Windows utility, and ABC-01 automatic backup configurator • Built-in MMS server based on IEC 61850-90-4 switch data modeling for Power SCADA • PRP (Parallel Redundancy Protocol)*: Transmit or receive two independent active paths to/from different LANs simultaneously on a zero recovery time network. • HSR (High-availability Seamless Redundancy)*: Every frame is duplicated and then transmitted in both directions of the HSR ring to deliver zero switchover time. *Only available with PM-7200 PRP/HSR series modules • Support for both End-to-End (2-step) and Peer-to-Peer (2-step) modes in Transparent Clock* • High precision time accuracy (under 1 μs) *Only available with PM-7200 PRP/HSR series modules.
