Introduction

Now you don’t have to worry about a controller hardware failure

interrupting your process and causing costly downtime. Using a

redundant controller, your process is automatically protected in

case of a hardware failure.

If an active controller fails, the standby controller takes over

automatically, providing uninterrupted control operation

without initialization or user intervention. The switchover

generates no disturbances to the field output signals, so your

process continues to run without impact. There is no special

cabling or configuration required to add redundancy, simply

add a controller to your existing hardware.

Redundant controllers also support the upgrade of controller

firmware and hardware online. You can therefore upgrade

your MD Plus to an MQ or MX or your SD Plus to an SQ or SX

controller online, with no configuration changes
