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 a
redundant 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-516A 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-516A 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 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.
