KJ4001X1-CG1

Events that can cause a switchover include.
„ Hardware failure within the active card.
„ Communications failure between the active card
and the controller.
„ Detection of a fault in the field wiring.
A switchover may also be initiated from the diagnostics
explorer, and the health and status of both cards and
their channels are available in the diagnostics explorer.
The system automatically commissions a new standby card.
In safe areas, failed cards can be replaced under power.
In hazardous areas, appropriate installation procedures
must be followed.

The DeltaV system provides control module level time
stamping for log events and alarms. For greater event
resolution, the 16-channel Sequence-of-Events DI card
can provide signal driven events to a resolution of +/- 0.25 ms
per card, or within 1 ms per controller. Please refer to
the Sequence-of-Events PDS for more information on
Sequence-of-Event data collection and system options
for this feature.

I/O Card Redundancy
Redundant I/O cards are available for critical applications.
The same card can be used in simplex or redundant
applications. When installed on a two-wide redundant terminal
block, the cards are recognized as a redundant pair by the
controller. The controller scans each card and determines which
card is acting as the active interface. When a fault is detected,
the system automatically switches to the standby I/O card.
DeltaV Control modules reference simplex and redundant
I/O channels identically and there is no special configuration
required to take advantage of redundancy.
Switchover of a redundant I/O card is completed within
two scans of the I/O bus. Make-before-break contacts ensure
digital field instruments remain powered and the process
is undisturbed. Analog output signals are briefly driven by
both cards for < 5 ms during switchover of the card.
Hardware Alerts automatically report hardware integrity errors
for both the primary and secondary cards. Any event that
causes a switchover is also reported automatically through the
system hardware alerts and is logged in the Event Chronicle.
