IEC 62439-3 Clause 4 (PRP) and IEC 62439-3 Clause 5 (HSR) are the newest standardized redundancy protocols for industrial automation networks where zero recovery time is needed. PRP and HSR are

suitable for electrical substation automation and other mission-critical applications that cannot tolerate any system downtime.

The EOM-G103-PHR-PTP series modules are compliant with the latest IEC 62439-3 standards and provide an easy and cost-effective integrated solution for adding a redundancy module to a non-IEC 62439-3 supported product. The modules support two IEC 62439-3 Ethernet ports (SGMII (MAC mode) / SERDES (1000Base-X) interface) for constructing PRP or HSR networks and one standard Ethernet port (SGMII (MAC mode) / SERDES (1000Base-X) interface) for connecting with standard IEEE 802.3 Ethernet devices. The EOM-G103-PHRPTP series also provide an extra SGMII (MAC mode) / SERDES (1000Base-X) interface for building up a local access Ethernet console port to easily maintain, control, and manage certain devices right at the local site.
