Standby

General
SCALANCE X switches support not only ring redundancy within a ring but also redundant
linking of rings or open network segments (linear bus). In the redundant link, rings are
connected together over Ethernet connections. This is achieved by configuring a
master/slave device pair in one ring so that the devices monitor each other and, in the event
of a fault, redirect the data traffic from the normally used master Ethernet connection to the
substitute (slave) Ethernet connection.
