Benefits

Uninterrupted control operation. By installing redundant

M-Series, S-Series and PK controllers, you can establish a

“safety net” to protect your process from unexpected controller

failures. The standby controller stands ready to maintain control

and process uptime in the face of hardware failures.

Online Upgrades. Installing redundant DeltaV controllers

enables you to perform online upgrades to your DeltaV system.

New firmware can be installed in the standby controller while

online without affecting operation. Once upgraded, the

standby is automatically configured and becomes available,

allowing a switchover to the new firmware without disrupting

the process. Once the switchover is complete, the original

active controller can then be upgraded. In addition, an MQ

controller can be upgraded online to an MX controller, and an

SQ controller can be upgraded online to an SX controller. This

ensures your system is always ready to expand as your control

strategy grows.

This ensures a bumpless transfer of control during the

switchover when using CHARM or DeltaV Classic I/O cards, with

or without Foundation™ fieldbus devices.
