DeltaV™ Controller Redundancy
DeltaV Controller Redundancy
The DeltaV™ redundant controller automatically protects your process in case of a hardware failure.
When an active controller fails, the standby controller takes over, providing uninterrupted control operation without initialization or user intervention. The switchover generates no disturbances to the field output signals and the process continues as though nothing had happened. DeltaV Controller Redundancy offers uninterrupted control operation and automatic commissioning.


  • Uninterrupted control operation
  • Supports online upgrades
  • Automatic commissioning
  • Bumpless transition
