Introduction
The Serial Interface provides a connection between the
DeltaV™system and devices that support a serial protocol,such
as Modbus or Allen Bradley’s Data Highway Plus.
The Serial Interface is supplied with Modbus software drivers
pre-loaded.Plug your Serial Interface into any available slot in
the I/O interface carrier,connect the third-party device,power
up and play.Like all DeltaV I/O,the Serial Interface may be
added online while the rest of the controller and I/O is powered
up and in use.
DeltaV Serial Interface I/O has a high level of reliability,
providing the process availability required for most applications.
In certain situations,process availability can be increased
through the use of Serial Interface I/O redundancy.
Benefits
Provides Seamless Information interface.Using the Serial
Interface with the DeltaV system,you gain an extended view
of your entire plant.All serial information is readily available for
display at the Operator Interface.
When connected to a PLC,DeltaV software may pass
supervisory information to the PLC facilitating the coordination
of control strategies across systems.
Plug-and-play ease of use.Plug-and-play installation saves
money.The Serial Interface works just like other DeltaV I/O
interfaces.It fits into any available slot on the controller I/O
carrier.There are no dipswitches.Just plug it in!
The DeltaV controller auto-senses the Serial Interface and
presents the configuration options.Online help makes this
interface a snap to configure.After a simple point-and-click
configuration exercise,your integrated solution is up
and running.
Extends the life of existing equipment.Enhance existing
capabilities—don’t replace them.Many plants have a variety of
devices already installed.With the Serial Interface you are able
to effectively interface a DeltaV system with existing PLCs or
other serial devices.This means that you can layer the state-ofthe-art process control offered by a DeltaV system on to the
devices you already have in place.
1:1 Redundancy for Serial I/O cards.You can add redundancy
to an existing system,providing the slave device supports
redundant serial ports.DeltaV redundant I/O uses the same
Series 2 I/O cards as non-redundant I/O.This allows you to
leverage your investment in installed I/O and in I/O spares.No
additional configuration is required.
Autosense of redundancy.The DeltaV system autosenses
redundant I/O,which greatly simplifies the task of adding
redundancy to the system.The redundant pair of cards is
treated as one card in the system tools.
Automatic Switchover.Should a primary I/O card fail,the
system automatically switches to the“standby”card without
user intervention.The operator is given clear notification of a
switchover at the operator display.
Product Description
The Serial Interface consists of a serial card and a terminal
block.The card contains two serial communications ports that
support RS232 and RS422/485 half duplex,or RS422/485 full
duplex signals.These ports are individually configurable and
support data rates up to 115 KBaud.
The card has the common DeltaV form factor,allowing it to be
plugged into any available slot in the I/O interface carrier.The
card is clearly labeled with the interface type.LEDs,located on
the front of the card,show the power,error,and port status of
the interface at a glance.
The standard Modbus protocol includes the Serial Interface,the
Modbus RTU,and ASCII communications protocol as defined in
the Modicon Modbus Protocol Reference Manual dated March
1992(PI-MBUS-300 REV D).Each Serial Interface port may be
configured as either a master or slave device.
The serial card supports the following features using the
Modbus protocol:
„Reading input data from Modbus coils,input status,holding
registers and normal input registers.
„Writing output data to coils and holding registers.
„Output data can be written in single coil,register mode,
or complete data set mode.This output mode is a
configurable parameter.
„Input data can be read in as a complete data set,providing
the best performance.
The serial card supports the input and/or output of 16
different data sets per serial port,for a total of 32 data
sets per Serial Interface.
Serial dataset registers can be referenced directly in control
modules as analog or discrete I/O providing fast easy data
exchange with the serial device.Direct module-to-Dataset/
register references are recommended for control signals.
Alternatively,users can read multiple registers form a Dataset
into a single“marshalling”module at the cost of a single DST.
Marshalling modules provide a cost effective way to integrate
serial data from analyzers and other data sources.
Serial dataset
registers can also be passed as SCADA values directly to
Workstations and Continuous Historians without
consuming DST’s.
Both Modbus RTU and Modbus ASCII communications modes
are supported by standard Modbus protocol.

Redundancy Made Easy
The Redundant Serial Interface consists of a pair of serial cards
and a redundant terminal block.The cards each contain two
serial communications ports that support RS422/485 half
duplex(in either single slave or multi-drop configurations),
or RS422/485 full duplex(in single slave configuration only),
as well as RS232.These ports are individually configurable
and support data rates up to 115 KBaud.
The active and standby serial cards are each connected to
serial ports on the slave device using the redundant terminal
block.Verify with the device supplier for its ability to support
redundant Modbus serial communications.
When a fault is detected,the system automatically
switches to the backup serial card.Events that can cause
a switchover include:
„Hardware failure within the active card
„Communications failure(including field cable and slave port
problems)between the active card and the controller
„Removal of the active card from the carrier
A switchover may also be initiated from control logic.This
allows additional watchdog logic to monitor multiple slave
devices for communication faults not detected by the
Serial Interface.A manual switchover can be initiated
from diagnostics explorer.
The controller scans each card of a redundant pair.Incremental
controller loading is a function of the number of redundant
cards.In addition,the redundant cards have dedicated
communication between the pair through the terminal block,
and the backup card monitors the health of the active card.
The reliability rating of the passive terminal block is greater
than the high reliability of the I/O cards.
The redundant pair can be manually configured or Autosensed.
A redundant pair is referenced by the odd-numbered address,
which infers the second card is to the right of this card.The
redundant terminal block couples the two cards as one
redundant pair that when Autosensed,the DeltaV system
automatically recognizes the redundant pair of cards and
assigns a device signal tag(DST)to the channels on the primary
card(Odd numbered card).
Switchover time for redundant I/O is minimal,and the process
will be undisturbed.Output channel behavior on switch over
can be configured to resend outputs on a switchover.This
can be coupled with Output Read back to ensure the output
channels are driven to the desired state upon switchover.
An alarm on the integrity error for the primary card notifies the
operator of a switchover.The backup card is also monitored
for integrity alarms.The system automatically commissions
and downloads a replacement standby card.In safe areas,
failed cards can be replaced under power.In hazardous areas,
appropriate installation procedures must be followed.

protocols downloaded directly into the serial card.Custom
