Ring Redundancy

Redundanz L2P
Release 5.0 04/09
If a section is down, the ring structure of a
X HIPER-(HIGH PERFORMANCE REDUNDANCY) Ring with up to 50 de-
vices typically transforms back to a line structure within 80 ms (setting:
standard/accelerated).
X 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).
X Fast HIPER-Ring of up to 5 devices typically transforms back to a line
structure within 5 ms (maximum 10 ms). If a larger number of devices is
being used, the reconfiguration time increases.
Device requirements for using the HIPER-Ring function:
X Within a HIPER-Ring, you can use any combination of the following
devices:
–RS1
– RS2-./.
– RS2-16M
–RS2-4R
– RS20, RS30, RS40
– RSR20, RSR30
– OCTOPUS
–MICE
–MS20, MS30
–Power MICE
– MACH 100
– MACH 1000
– MACH 3000
– MACH 4000
X Within an MRP-Ring, you can use devices that support the MRP protocol
based on IEC62439.
X Within a Fast HIPER-Ring, you can use any combination of the following
devices:
– RSR20, RSR30
– MACH 1000
Note: Enabled Ring Redundancy methods on a device are mutually exclu-
sive at any one time. When changing to another Ring Redundancy method,
deactivate the function for the time being.
