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
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).
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.
X Within a HIPER-Ring, you can use any combination of the following
devices:
– PSSnet SHL
X 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:
X Select one of the available Ring Redundancy versions, or change it.
X Display an overview of the current Ring Redundancy configuration.
X Create new Ring Redundancies.
X Configure existing Ring Redundancies.
X Enable/disable the Ring Manager function.
X Receive Ring information.
X Delete the Ring Redundancy.
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.
