Redundant linking of rings
X-200IRT IE switches support not only media redundancy in ring topologies but also the
redundant linking of HRP rings. These also include interrupted HRP rings; in other words,
buses. With a redundant link, two HRP rings are linked together via two Ethernet
connections. This is achieved by configuring a master/slave device pair in one ring so that
the devices monitor each other over the ring ports and, in the event of a fault, redirect the
data traffic from one Ethernet connection (standby port of the master) to another Ethernet
connection (standby port of the slave).
You will find further information on Ethernet cabling and the topological positioning of master
and slave in the SCALANCE X-200 operating instructions in the section "Network topologies
and media redundancy".
Note
• The function is supported only by X-200IRT IE switches.
• To be able to use the function, HRP must be activated.
Standby manager
The standby manager allows the redundant linking of two HRP rings. To do this, two
neighboring devices within a ring must be configured as standby partners.
Enable the standby manager for both standby partners and select the port via which the
module is connected to the ring you want to link to.
For the "Standby Connection Name", a name unique within the ring must be assigned for
both partners, This identifies the two modules as standby partners that belong together.
Modules already being used as HRP managers cannot be configured as standby partners at
the same time.
