ControlLogix Redundancy Alias Topic Switcher 2.0

ControlLogix Redundancy Alias Topic Switcher, developed by Rockwell Software, Inc., is a utility designed to keep client applications seamlessly connected to the active controller in a ControlLogix redundant architecture. It monitors the redundancy state of paired ControlLogix controllers and automatically redirects an alias topic—commonly used in RSLinx Classic—to the current primary controller. This ensures HMIs, historians, and other OPC/DDE clients continue to read and write data without manual intervention during a switchover or planned maintenance.

Key capabilities:

• Automatic alias topic reassignment to the active (primary) controller during redundancy switchover
• Support for high-availability ControlLogix systems to minimize downtime and data gaps
• Transparent operation for client applications (e.g., HMI, SCADA, historian, and custom OPC/DDE clients)
• Configurable behavior and logging to aid diagnostics and compliance
• Option for manual failover control to support maintenance and testing

Ideal for process and manufacturing environments that rely on ControlLogix redundancy, this tool helps maintain continuity, reduce operator workload, and improve overall system resilience by eliminating the need to manually retarget communications after a controller changeover.
