Using Communication Redundancy
Setting up Communication Redundancy on your network helps protect critical links against failure,
protects against network loops, and keeps network downtime at a minimum.
The Communication Redundancy function allows the user to set up redundant loops in the
network to provide a backup data transmission route in the event that a cable is inadvertently
disconnected or damaged. This is a particularly important feature for industrial applications, since
it could take several minutes to locate the disconnected or severed cable. For example, if MOXA
EDS-726 is used as a key communications component of a production line, several minutes of
downtime could cause a big loss in production and revenue. MOXA EDS-726 supports two
different protocols for this communication redundancy function—Rapid Spanning Tree Protocol
(IEEE-802.1w) and Turbo Ring.
Turbo Ring and STP/RSTP cannot both be used on the network at the same time. The table below
lists the key differences between each feature. Use this information to evaluate the benefits of each,
and then determine which features are most suitable for your network.

Recovery Time < 300 ms Up to 30 sec. Up to 5 sec
Gigabit Ethernet Redundant Ring Capability (< 300 ms)
Ethernet has become the default data communications medium for industrial automation
applications. In fact, Ethernet is often used to integrate video, voice, and high-rate industrial
application data transfers into one network. MOXA EDS-726, which comes equipped with a
redundant Gigabit Ethernet protocol called Gigabit Turbo Ring, gives system maintainers a
convenient means of setting up a versatile yet stable Gigabit Ethernet network. With Gigabit
Turbo Ring, if any segment of the network gets disconnected, your automation system will be
back to normal in under 300 ms.
