There are no dip-switches, jumpers or addresses to assign. The
standby controller is automatically assigned the appropriate
standby address and begins working, protecting your process.
Bumpless transition. DeltaV controllers are designed for a
bumpless transfer of control from the active controller to the
standby controller. During this time, output channels hold
their output states until the switchover is complete and control
modules begin executing. The control module uses signal status
to ensure all I/O channels are good before taking control action
on them, and all output signals are synchronized through I/O
readback features to ensure control calculations are based on
current output states.
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.
