Configuration
Configure button
Click the Configure button to open the 2460 System Hub Redundancy Configuration window. This window
lets you configure various options for fail-over and other redundancy related issues. You may also set
separate Modbus addresses for the two system hubs.
Individual Modbus address
By setting individual Modbus addresses for the Primary and Backup devices, a host system may
communicate with each device separately. This is useful, for example, for verifying the current status of
each device.
