The
Turbo Ring protocol was introduced by MOXA about
four years ago to provide system integrators with a cost-effective,
easy-to-configure, highly-reliable redundant ring capability.
MOXA has now released a "new generation Turbo Ring" protocol
that provides users with greater flexibility in setting up
redundant networks.
MOXA Unveils World's Fastest Ring Redundancy
Redundancy
plays an important role in increasing the reliability of
systems used for industrial automation applications, and
the redundant network technology called "Turbo Ring," which
was developed by MOXA, now provides the world's fastest redundant
Ethernet recovery time of under 20 milliseconds. With MOXA
Turbo Ring,
if any segment of the network is disconnected, your automation
system will be back to normal in less than 20 milliseconds,
even at a full load of 250 switches.
The new generation MOXA Turbo Ring offers users a broad choice of topologies,
including Ring Coupling, Dual-Homing, and Dual-Ring, to give system maintainers more convenience and flexibility when setting up
industrial Ethernet networks.
Ring
Coupling Topology
For some systems it may not be convenient to connect all devices in the system to create one BIG redundant ring, particularly since some of the devices could be located at a remote site. Turbo Ring's "ring coupling" function
helps you separate those distributed devices into different,
smaller redundant rings, and in such a way that the smaller
rings will still be able to communicate with each other.
In addition, the new generation Turbo Ring does not require a control line, which
for many applications results in a significantly lower
cost.
Dual-Homing
& Dual-Ring Topologies
The
new generation Turbo Ring provides two new topologies
that give integrators more choices when setting up
a redundant network.
 Dual-Homing: You
may also configure a ring for "dual-homing," which involves using a single Ethernet switch in one ring to connect to one
or two switches in an adjacent ring. With dual-homing,
one or both rings (e.g., Ring B in the figure at the right)
only needs one switch, making it cheaper and more convenient
to provide a small number of devices with network redundancy.
Dual-homing also gives automation engineers the option of providing legacy devices
with a certain level of redundancy. For example, some PLCs
may be Ethernet-ready, but only have one Ethernet port.
In this case, the "MOXA switch + PLC" combo would represent a 1-switch ring that connects to another ring or to the
network backbone.
 Dual-Ring: The "dual-ring" option provides another cost-saving configuration, since in this case two adjacent rings share one switch. This type of configuration is ideal for applications that have inherent cabling difficulties.
Benefits
and Products
Different automation applications require different levels of redundancy. Turbo Ring provides media redundancy, and only Turbo Ring's fast 20 ms recovery time is sufficient for many critical automation systems (compared with Spanning Tree Protocol which has a recovery time of several seconds).
The following MOXA managed switches all support the
new generation Turbo Ring:
Another great feature of the new generation Turbo Ring is that you can configure
switches housed at remote sites to use Turbo Ring, and then connect the Turbo
Ring
to a an
STP/RSTP
network
that uses switches from other vendors. Mixing Turbo Rings that use MOXA
switches with networks using STP/RSTP is particularly useful when you need
to connect
your remote industrial networks to your climate-controlled control room
network.
The new generation Turbo Ring gives you the world's fastest redundant and most
reliable ring solution, but with the flexibility you need to deploy
sophisticated,
cross-vendor networks.
