Ethernet Protocols:

Modbus TCP Interface

The Modbus TCP interface will support Modbus data

sources such as PLCs, MCCs, analyzers and similar devices

communicating Modbus TCP. The Modbus TCP interface is a

Modbus Client reading and writing data from/to Modbus Server

devices. The Modbus server devices can be Modbus TCP devices

or Modbus serial devices using a Modbus TCP gateway.

The Modbus TCP interface supports the following types of

data access:

„ Reading input data from Modbus Coils, Discrete Input,

Holding Registers, and Input Registers.

„ Writing output data to Coils and Holding registers.

All reads will be performed periodically and outputs will be

sent when they are written.

EtherNet /IP

The EtherNet/IP protocol allows data sources such as

PLCs, Intelligent Field Devices (IFDs), variable-speed drives,

MCCs, and analyzers; as well as other devices communicating

EtherNet/IP to connect directly in to DeltaV via the EIOC.

The EtherNet/IP interface will support connections for

both implicit and explicit messaging to allow access to both

Class 1 and Class 3 EtherNet/IP I/O adapters. Redundancy with

EtherNet/IP Class 1 Implicit and Class 3 Explicit messaging

for control (sending outputs to the devices) require special

considerations due to exclusive owner communications defined

by the protocol. Please refer to the DeltaV System Planning

Guide for more information. Class 3 PCCC and UCMM with

Logix tags message classes are also supported.

Product Description

The EIOC is a big pipe for the integration of process data from

3rd party Ethernet Devices, such as PLCs and smart field devices

such as Intelligent Field Devices (IFDs) and Intelligent Electronic

Devices (IEDs). A network of these Ethernet Devices can be

directly connected to the EIOC. The Ethernet Devices can

communicate to the EIOC using one of five protocols;

Modbus TCP, EtherNet/IP, IEC61850 MMS, OPC UA client

and EtherNet/IP Control Tag Integration. The EIOC connects

directly into the DeltaV Control Network and can be placed

remotely in an enclosure in the field.

The EIOC is an independent embedded data server. This means

that there is no need for a separate controller to process the

data being integrated into the EIOC. Control Modules needed

to process the data from the Ethernet Devices are assigned and

executed in the EIOC. In this way, communications with the

devices are fast and direct. Any parameters from the modules

running in the EIOC can be read by both S-series and M-series

controllers using External References when needed in control

strategies at the controller level.

„ Powerful solution that communicates directly

to external Ethernet Device Networks

„ Easy connection to devices using Modbus TCP,

EtherNet/IP, IEC61850 MMS, OPC UA client or

EtherNet/IP Control Tag Integration protocols

„ Proven S-series packaging

„ Modular with easy to add redundancy

„ Communication to any M- and S-series Controller

Introduction

The Ethernet I/O Card (EIOC) provides a platform to access data

from Ethernet devices in the DeltaV™ system. Ethernet Devices

capable of talking Modbus TCP, EtherNet/IP, IEC 61850 MMS

(Manufacturing Message Specification), OPC UA client and

EtherNet/IP Control Tag Integration protocols are supported.

The EIOC provides monitoring and control of Ethernet Devices

on the Ethernet Device Network via control modules assigned

to and executed in the EIOC. Ethernet Devices like PLCs,

Motor Control Centers, drives, switchgear and others can be

controlled directly by the EIOC, independent of a controller

Product Description

The WIOC is a native DeltaV I/O node that supports up to 100

wireless devices. The cards install on a 2-wide carrier, with each

card having its own Smart Wireless Field link. The WIOC can be

commissioned in a simplex mode if no redundancy is needed.

The WIOC allows redundancy to be completed later, when

needed – online and bumpless.

The WIOC carrier has two Ethernet IO Ports that connect to the

DeltaV Area Control Network and are available with copper or

fiberoptic media. The Smart Wireless Field links are connected

to the I/O card using a 4-conductor cable. The cable has a pair of

wires for power and a pair for the communication to the

field link.

The WIOC uses the Smart Wireless technology supported by

WirelessHART devices and a Self-Organizing Network.

„„ No wireless expertise is required; devices automatically find

the best communication paths with Adaptive Mesh Routing.

„„ Network continuously monitors paths for

degradation and repairs itself.

„„ Adaptive behavior provides reliable, hands-off

operation and simplifies network deployments,

expansion, and reconfiguration.

Product Description

The SX controller primary function is to execute control

modules that are designed to meet the specific control

requirements of the plant. These control modules use process

signals from the controller’s I/O subsystem and provide

communication of process data to the rest of the DeltaV

control system for operator interaction and data collection.

Each controller node can be installed as a simplex or redundant

node. The controllers are connected to the I/O carriers,

which are mounted to the right of the controller carriers.

Up to 8 carriers with 8 cards each can be connected to the

local bus I/O, for a total of 64 traditional I/O cards. In addition

to the 8 local I/O carriers, each controller can communicate

with an additional 16 Remote I/O units hosting traditional

card based I/O.

„ Scalable controllers

„ Quick assembly

„ Easy-to-use

„ Field proven architecture

„ Designed for Electronic Marshalling

„ Advanced controls

Introduction

The DeltaV™ SX controller provide communication and

control functions and integrate field devices and the other

nodes on the control network. The SX and SQ controllers

provide a choice to match the controller capacity to the

requirements of the process. They also provide new ease

of use features that eliminate mounting screws and accelerate

cabinet assembly.

Control strategies and system configurations created on

earlier DeltaV systems can be used with this powerful

controller. The SX Controller provides all the features

and functions of the M-series controllers including support

for CHARM based Electronic Marshalling.

The control languages executed in the controllers are

described in the Control Software product data sheet.

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.

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.

The S-series traditional I/O subsystem includes:

• I/O interface carrier (DIN-rail surface mounted) on which

all I/O related components are installed.

• Bulk AC to 24V DC power supply for field devices.

• A variety of analog and discrete I/O interfaces, consisting

each of an I/O card enclosed in a common form factor and

an associated I/O terminal block, which easily plug into the

I/O interface carrier.

• Cable extenders that provide flexibility in carrier mounting.

The I/O cards are connected to the field with a terminal block,

which allows removal of I/O cards without disconnecting any

field wiring.

DeltaV DCS provides control module level time stamping for log

events and alarms. For greater event resolution the 16-channel

Sequence of Event 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.
