Communication Redundancy

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 EtherDevice Server 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 Ethernet Device Server supports two different protocols to
support this communication redundancy function—Spanning Tree
Protocol (IEEE 802.1D) and Turbo Ring.
You are only allowed to select one of these two protocols, with the
selection procedure illustrated in the following screen shots.
