NOTE Most of Moxa’s managed switches now support three proprietary Turbo Ring protocols:
1. “Turbo Ring” refers to the original version of Moxa’s proprietary redundant ring protocol, which has a
recovery time of under 300 ms.
2. “Turbo Ring V2” refers to the new generation Turbo Ring, which has a recovery time of under 20 ms.
3.
“
Turbo Chain” is a new Moxa proprietary protocol with unlimited flexibly to allow you to construct any
type of redundant network topology. The recovery time is under 20 ms.
In this manual, we use the terminology “Turbo Ring” ring and “Turbo Ring V2” ring to differentiate between
rings configured for one or the other of these protocols.
Gigabit Ethernet Redundant Ring Capability (< 50 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. The EDS-P510, 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 less than 300 ms (Turbo Ring) or 50 ms (Turbo Ring V2).
Gigabit Turbo Ring
Recovery Time < 50 ms
NOTE Port trunking and Turbo Ring can be enabled simultaneously to form a backbone. Doing so will increase the
bandwidth of the backbone, and also provide redundancy. For example, suppose that two physical ports, 1
and 2, are trunked to form trunk group Trk1, and then Trk1 is set as one Turbo Ring path, if port 1 gets
disconnected, the remaining trunked port, port 2, will share the traffic. If port 1 and port 2 are both
disconnected, Turbo Ring will create the back up path within 300 ms.
The Turbo Ring Concept
Moxa developed the proprietary Turbo Ring protocol to optimize communication redundancy and achieve a
faster recovery time on the network.
The Turbo Ring and Turbo Ring V2 protocols identify one switch as the master of the network, and then
automatically block packets from traveling through any of the network’s redundant loops. In the event that one
branch of the ring gets disconnected from the rest of the network, the protocol automatically readjusts the ring
so that the part of the network that was disconnected can reestablish contact with the rest of the network.
