Orion Redundancy

These Orions are Redundant

Hot Active-Standby Redundancy replicates operator HMI bi-directionally and minimizes duplicated and/or missed events without interruption.

The OrionLX CPX and the OrionLXm can be configured as a hot-standby redundant pair to support applications as a SCADA RTU, substation HMI, Alarm Annunciator, SOE Recorder and substation controller with low-speed to medium-speed logic.  Both Orions run identical NCD configurations, logic and webpage configurations, and configurations are auto-replicated between the two.

Key Features

  • Communication to DNP3 SCADA minimizes missed events and avoids duplicate events during switchover using OrionLX database synchronization.
  • TCP SCADA can poll to a single TCP at a single IP address.  The “Active” OrionLX assumes an alias IP address to make this possible.
  • Serial SCADA interacts with Active Orion until throwover is required to Standby. Event buffers are intelligently managed to avoid event floods.
  • Tags and Tag Log, Acknowledged Alarms, and Blocked Points and other operator-initiated actions are replicated bi-directionally (Active-to-Standby and Standby-to-Active), so operators can use either HMI for viewing status, placing tags, acknowledging alarms, blocking points or executing controls.
  • OrionLX Math & Logic schemes are simplified though database synchronization.
  • All IEDs can be polled by both Active and Standby Orion, ensuring that the communication health of the Standby Orion is known prior to throwover.
  • Communication health and other diagnostic data is continuously monitored between Standby and Active Orion.
  • Throwover to the Standby OrionLX can be accomplished manually or automatically.
  • A “Standalone” mode is offered for testing configurations and upgraded firmware.
  • NCD, Math & Logic and SVG webpage configurations and SVG pages loaded to Active Orion are automatically transferred to Standby Orion.
  • A redundancy diagnostic and status webpage provides intuitive situational awareness


  • Orion Products Overview Brochure  

    The Orion Family of Substation Automation Platforms and I/O perform an expanding array of automation and security applications in electric utility substations, with minimal setup and maintenance. A single Orion can replace multiple legacy boxes in a substation, reducing hardware, design, wiring, and panel costs.
