The DRDAS operation mode provides a highly redundant network structure that takes advantage
of CN2610’s dual LAN ports, dual IP addresses, and dual MAC addresses. DRDAS uses a backup
PC that is set up to take over when the primary PC fails.
CN2610’s dual-host redundant configuration sends serial data to 4 IP addresses on the network.
Users select a Primary IP and 3 Secondary IPs. When the Primary IP fails, the backup IPs take
over by using the switching library (refer to Chapter 7 for more details).
With this kind of redundant setup, if one of the secondary IPs tries to send commands to the serial
device, the commands are discarded by the CN2610, since only the Primary IP is allowed to
conduct bi-directional transmission. The backup IPs are only allowed to receive data from the
CN2610.
