Emerson DeltaV™ Redundant Controller Product Description

Product description

For critical process control applications that cannot tolerate interruptions, the DeltaV system provides controller redundancy.

For critical process control applications that cannot tolerate interruptions, DeltaV systems offer controller redundancy.

The redundant controller contains the same control strategy as the active controller.

A redundant link transmits control parameters to the standby controller

to ensure that it is ready to take over from the active controller.

parameters to the standby controller to ensure that it is ready to take over control if needed.

When redundancy is enabled, each module calculates the updates required by the standby controller.

These updates are transmitted to the standby controller via the redundant link.

These additional operations of controller redundancy Redundancy typically reduces CPU idle time by about 10%. About 10 percent.

When a failure is detected, the standby controller can take over without affecting the process control signals.

The DeltaV Event Chronicle stores a record of each switchover and the reason for the switchover, if a reason has been determined.

Replacing an existing standby controller is as simple as removing the existing unit and installing a new controller.

Replacing an existing standby controller is as simple as removing the existing unit and installing a new controller.

The activated controller will detect the spare controller and the system will automatically debug and download the new hardware.

Redundancy In addition to redundant hardware, a redundant license is required.

Redundant controllers Redundant controllers are shown as individual nodes in the Explorer window, represented by the Redundant Controller icon.
