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 the Industrial Ethernet
switch is using a key communications component of a production line, several minutes of downtime
could cause a big loss in production and revenue. Weidmueller Switches supports the following
different protocols to support communication redundancy function:
Rapid Spanning Tree/ Spanning Tree Protocol (IEEE 802.1W/1D),
Turbo Ring / Turbo Ring V2
and Turbo Chain.
When configuring a redundant ring, all switches on the same ring must be configured to use the
same redundancy protocol. You cannot mix the "Turbo Ring," "Turbo Ring V2," and STP/RSTP
protocols on the same ring. The following table 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
NOTE
All of Weidmueller's managed switches now support the three Turbo Ring protocols:
(1) "Turbo Ring" refers to the first version of 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.
