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. Moxa CN2650-8 terminal server uses its built-in Dual-LAN ports to implement a “Redundant COM” mode that keeps applications running uninterrupted.

 

Dual-LAN Redundancy

Moxa CN2650-8 features 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 CN2650-8 (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 CN2650-8 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. Moxa CN2600 software is programmed to automatically discard duplicate data packets.

 

Dual-host Redundancy

CN2650-8 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 CN2650-8.

 

Dual-AC Model Supported

Dual-power redundancy uses two power inputs and redundant internal power supplies to ensure CN2650-8 functions even during power circuit failures.
