Redundancy

6.1 Ring Redundancy

The concept of the Ring Redundancy enables the construction of high-
availability, ring-shaped network structures.
If a section is down, the ring structure of a
 HIPER-(HIGH PERFORMANCE REDUNDANCY) Ring with up to 50
devices typically transforms back to a line structure within 80 ms (possible
settings: standard/accelerated).

MRP (Media Redundancy Protocol) Ring (IEC 62439) of up to 50 devices
typically transforms back to a line structure within 80 ms (adjustable to
max. 200 ms/500 ms).
With the aid of a device's Ring Manager (RM) function you can close both
ends of a backbone in a line-type configuration to form a redundant ring.
 Within a HIPER-Ring, you can use any combination of the following
devices:
– RS2-./.
– RS2-16M
– RS2-4R
– RS20, RS30, RS40
– RSR20, RSR30
– OCTOPUS
– MICE
– MS20, MS30
– PowerMICE
– MACH 100
– MACH 1000
– MACH 3000
– MACH 4000

Within an MRP-Ring, you can use devices that support the MRP protocol
based on IEC62439.

Within a Fast HIPER-Ring, you can use any combination of the following
devices:
– RSR20, RSR30
– MACH 1000
Depending on the device model, the Ring Redundancy dialog allows you to:
 Select one of the available Ring Redundancy versions, or change it.
 Display an overview of the current Ring Redundancy configuration.
