HiPER Ring – Network Redundancy

How does HIPER-Ring redundancy work?

...and how can you build a redundant and secure networkusing Hirschmann‘s managed industrial Ethernet switches (RS2-XX/XX and MICE Series)?

Fiber optic or twisted pair backbone

Hirschmann switches can interconnect the four areas via twisted pair or fiber optic cable.

Is this network resilient enough?

If only one of the three backbone connections fail, communication will be lost to one or more areas.

Solution via HiPER-Ring!

Redundant Link

Creating a redundant ring prevents communication loss should one of the backbone links fail.

HiPER-Ring Watchdog Packets

Redundant Link

Watchdog packets pass through redundant link while normal Ethernet traffic cannot.

The Redundancy Manager sends out watchdog packets to test the integrity of the ring.

As before, the network switches over within a maximum of 300 milliseconds and continues to monitor network integrity.

Restoring broken link

When the broken connection is repaired, the Redundancy Manager sets the network into it’s normal operational mode. 8

HiPER-Ring structure benefits

Hirschmann’s HiPER-Ring Structure• Optimized resiliency for today’s

Ethernet networks

• Redundancy Manager standard in all Hirschmann’s RS2-XX/XX and MICE switches

• Fast learning in a ring is guaranteed by sending “clear address table” messages

• Max. reconfiguration time of 300 ms – reducing machine/production downtime

• Exchange of devices and network extension is possible during operation

• Simple and clear topology• Up to 50 switches in a ring• Plug & Play (with or without

management)
