Introduction
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.
Dual-LAN Redundancy
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.
Redundant COM
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
data packets.
