Redundancy is an important issue for industrial networks, and various types of solutions have been developed to provide alternative network paths
when equipment or software failures occur. “Watchdog” hardware is installed to utilize redundant hardware, and a “Token”- switching software
mechanism is applied. The CN2600 terminal server uses its built-in Dual-LAN ports to implement a “Redundant COM” mode that keeps your
applications running uninterrupted.
The CN2600 has two separate LAN ports that can be connected to
separate LAN networks. Dual-LAN redundancy involves setting up
two separate physical networks to connect the PC host with the
CN2600 (the PC host also requires two LAN cards). If one connection
fails, the PC host can still communicate with your serial devices over
the alternative LAN connection.
Moxa offers “Redundant COM,” an easy-to-use application to provide
an alternative solution for network redundancy. When the CN2600
receives a data packet from a connected device, two identical data
packets are sent over two independent LAN connections to prevent
lost data packets if one LAN connection becomes unavailable. The
CN2600 software is programmed to automatically discard duplicate
The CN2600’s dual-LAN cards can also be used to set up “dual-host”
redundancy. In this case, both networks (LAN A and LAN B in the
figure) are connected to two different hosts. If either of the two hosts
shuts down unexpectedly, the other host will still be able to
communicate with serial devices connected to the CN2600.
Dual-AC Model Supported
Dual-power redundancy uses two power inputs and redundant
internal power supplies to ensure that all of the CN2600’s functions
will be available, even in the event of power circuit failures.
