Key Features:
- Zero Downtime Redundancy – Seamless failover during CPU/network/power faults.
- Deterministic Control – Real-time task scheduling for motion/time-critical processes.
- Cyber Security – Built-in firewall, role-based access, and encrypted communications.
- Data Historian – Stores 100k+ tags for trend analysis.
- Hot-Swap Maintenance – Replace modules without system shutdown.
- Edge Computing – Runs C/C++/Python scripts via embedded Linux® runtime.
Primary Function & Purpose:
Provides mission-critical fault tolerance for continuous industrial processes by:
- Maintaining synchronized memory between primary/backup CPUs.
- Executing safety logic for emergency shutdowns (ESD).
- Preventing production loss during hardware failures.
Typical Applications:
- Power Plant Control – Turbine sequencing, grid synchronization.
- Oil & Gas Safety Systems – Fire/gas detection, pipeline ESD.
- Water Treatment – SCADA for pumping/filtration networks.
- Manufacturing – High-speed assembly line control.
- Transportation – Tunnel ventilation control, bridge monitoring.
Application Fields:
Deployed in 24/7 continuous operations across:
- Energy: Nuclear/Hydro power backup control, substation automation.
- Chemical Plants: Batch reactor safety interlocks.
- Minerals Processing: Conveyor/grinding mill control.
- Infrastructure: Traffic management, airport baggage systems.
