Introduction

Emerson Process Management continues its long-standing

excellence in providing solid control solutions with the S-Series

DeltaV™ Controller Interface for PROVOX I/O and DeltaV SQ

or SX Controllers. You can transition to DeltaV controllers

and connect to PROVOX I/O already installed in your plant,

continuing to maximize your original PROVOX I/O investment.

The DeltaV Controller Interface for PROVOX I/O can be used

with both Control I/O and Distributed (MUX) I/O, which

connects using the serial buffer card. The interface to PROVOX

I/O uses an SQ or SX controller and a DeltaV power supply

installed on the PROVOX I/O Carrier.

With this solution, PROVOX I/O support is integrated into

standard DeltaV engineering and diagnostics, including DeltaV

Explorer and Control Studio.

The redundant pair can be manually configured or

Autosensed. 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

datasets 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.

Other Protocols Supported

The DeltaV S-series Serial Card can support other serial

driver protocols downloaded directly into the serial card.

Custom drivers available from Emerson for the DeltaV serial

card include:

• Allen-Bradley Data Highway Plus

• Mettler Weight Scale

• Redundant Enhanced Modbus

• Sartorius Weight Scale

Call your local sales office for availability of custom drivers.

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.

Slave devices must provide two serial ports in order to allow

the active and standby serial cards to be connected. The

Active card continually poll input data and writes output

data to the device on one serial link, while the standby card

periodically polls the slave device for a diagnostic register.

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

• Loss of Communications (including field cable and

slave port problems) between the active card and the

slave device

• 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 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.

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 from 300 Baud up to

115 KBaud.

The S-series card plugs into an 8-wide I/O carriers in any of

the possible 64 slots and communicates with the S-series

controllers. 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.

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-of- the-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

Serial interfaces as simplex cards or redundant pairs.

The interfaces automatically detect the presence of

the redundant terminal block and are autosensed by

the system as a redundant pair. There is no additional

configuration. Use redundant Serial interfaces with slave

devices that support redundant serial ports.

Automatic switchover. Should a primary Serial

Interface 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. The standby card continually polls the

slave devices for diagnostic to confirm its ability to take

over communications.
