Redundancy
6.1 Ring Redundancy
The concept of the Ring Redundancy enables the construction of high-avail-
ability, ring-shaped network structures.
If a section is down, the ring structure of a
HIPER-(HIGH PERFORMANCE REDUNDANCY) Ring with up to 50 de-
vices typically transforms back to a line structure within 80 ms (setting:
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 help of the Ring Manager (RM) function of a device, you can connect
both ends of a backbone in a line structure to form a redundant ring.
With the help of the Ring Manager (RM) function of a device, you can connect
both ends of a backbone in a line structure to form a redundant ring.
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
Within an MRP-Ring, you can use devices that support the MRP protocol
based on IEC62439.
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.
Create new Ring Redundancies.
Configure existing Ring Redundancies.
