The DeltaV controller redundancy function is applicable to M-series, S-series (including SZ type), and PK type controllers, aiming to avoid critical process interruptions and high downtime losses caused by controller hardware failures through the "primary backup controller" mode. The core advantages can be summarized as four key features:
Uninterrupted control operation: When the main controller fails, the backup controller automatically takes over without initialization or manual intervention. The on-site output signal is undisturbed and the process continues to run; No special wiring or additional configuration is required, redundancy can be achieved by simply adding controllers to the existing hardware foundation.
Online upgrade capability: Supports online upgrade of controller firmware and hardware. New firmware can be installed on the backup controller first (without affecting the current operation), and the backup controller will automatically configure and support switching after the upgrade is completed. After switching, the original main controller will be upgraded; At the hardware level, it supports online upgrades from MQ to MX and SQ to SX, meeting the requirements for expanding control strategies.
