How Turbo Chain Works
Moxa’s Turbo Chain outperforms traditional ring topologies by providing great flexibility, unrestricted
expansion, and cost-effective configurations when connecting separate redundant rings together—in a
simplified manner. With Turbo Chain, you can create any complex redundant network that correspond to
your needs, while still ensuring great reliability and availability for your industrial Ethernet network
applications.
With Moxa's Turbo Chain, network engineers have the flexibility to construct any type of redundant topology
with minimum effort－by simply linking Turbo Chain to the Ethernet Network. Turbo Chain allows for
unrestricted network expansion. Network engineers no longer need to go through the hassle of
reconfiguring the existing network, and can simply use Turbo Chain to scale up their redundant networks.
How to Determine the Redundant Path
Here is an example of how to set up Turbo Chain and determine the redundant path.
1. Select the Head switch, Tail switch, and Member switches.
2. Configure one port as the Head port and one port as the Member port in the Head switch, configure one
port as the Tail port and one port as the Member port in the Tail switch, and configure two ports as
Member ports in each of the Member switches.
3. Connect the Head switch, Tail switch, and Member switches as shown in the diagram below.
The path connecting to the Head port is the main path, and the path connecting to the Tail port is the
backup path of Turbo Chain. Under normal conditions, packets are transmitted through the Head Port to the
LAN network. If any Turbo Chain path is disconnected, the Tail Port will be activated so that packet
transmission can continue.
