DeltaV System Overview

This chapter gives an overview of the DeltaV digital automation system. It takes a

brief look at the hardware, describes the basic concepts and terminology, introduces

the major software components, and ends with a summary of the ways you can find

out more about the DeltaV system from the Help and Books Online.

Hardware

The manual, Installing Your DeltaV Digital Automation System, also available as an online

book, describes the DeltaV system hardware and provides instructions for installing

and powering up the system.

The I/O subsystem also supports Serial interface cards as well as the Ethernet I/O interface.

These various I/O products provide a wide range of interfaces to meet the needs of your control application.

The SD Plus also supports CHARMS and WirelessHART IO cards.

The CHARMS I/O card (CIOC) connects via the redundant Ethernet

ports of the controller and provide a highly distributed and flexible I/O solution called Electronic Marshalling.

Up to 16 CIOC’s can communicate with one controller, each providing up to 96 individually configurable signal types.

The WirelessHART I/O card provides redundant communication for up to 100 WirelessHART devices,

providing high availability and reliability of wireless data.

Up to 16 Wireless HART I/O cards can communicate to a single controller.

Control modules are automatically scheduled by the controller, based on their assigned scan rates.

This allows each control function to be optimized based on the process dynamics.

Modules scan times can be set as fast as 100 ms, and as slow as 60 seconds.

The number of control modules that can be assigned to a controller depends

on the complexity and scan rate of each module, and the available CPU and memory.

Product Description

The SD Plus controller executes control logic based on the process signals derived

from the I/O subsystem and provides communication 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.

Redundancy is provided by adding a second controller and power supply

mounted adjacent to the primary controller.

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.

In addition to traditional I/O cards, the local bus supports field bus technologies,

including Foundation fieldbus, Profibus DP, DeviceNet and AS-I protocols.

 Scalable controllers

 Quick Assembly

 Easy to use

 Field Proven architecture

 Designed for Digital Marshalling

 Advanced Controls

Introduction

The DeltaV S-Series controllers provide communication and control functions and integrate

field devices and the other nodes on the control network.

The SX and SD Plus 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 controller.

The SD Plus Controller provides all the features and functions of the M-Series controllers with the added support for CHARM based Digital Marshalling.

The control languages executed in the controllers are described in the Control Software product data sheet

Benefits

Non-Intrusive DeltaV I/O simulation. Use the VIM2 in conjunction with the

MYNAH Technologies’ MiMiC Simulation Software to simulate your DeltaV M-Series I/O and digital bus field devices.

 Supports DeltaV I/O modules. Provides completely non-intrusive simulation of all DeltaV M-series I/O Modules.

Supports autosensing of I/O and accurate testing of controller loading.

DeltaV configuration can be fully tested without modifying the control strategies.

 Digital bus support. Provides simulation of all DeltaV Digital Busses and Foundation Fieldbus function blocks.

Supports Foundation Fieldbus control in the field configuration testing.

 Powerful simulation solution. Provides full simulation of up to 64 DeltaV I/O modules per controller.

Introduction

The DeltaV M-series Virtual I/O Module 2 (VIM2) provides nonintrusive simulation of the

DeltaV M-series I/O Cards and digital bus field devices for process simulation

when used with MYNAH Technologies’ MiMiC Simulation Software.

DeltaV Control strategies and system configurations can be fully tested with this powerful simulation interface.

The VIM2 also provides an interface to Ethernet I/O networks and devices that

use the Modbus TCP/IP or Ethernet/IP protocol drivers.

DeltaV M-series controllers can read and write signals from plant floor devices connected

to Ethernet I/O networks such as PLC’s, Motor Control Centers, and Weigh Scales.

Powerful integration solution. Use the VIM2 in conjunction with the MYNAH

Ethernet I/O drivers to integrate your DeltaV system with your Ethernet I/O device networks.

 Large device capacity. Each VIM emulates four DeltaV Serial Cards and support up

to 128 Serial Card Datasets of information from 32 network devices in simplex installations and 16 devices in redundant installations.

Communication over the Ethernet I/O device network is fast and efficient.

 Flexible networking. User configurable IP addressing allows the VIM2 to be used in almost any

plant environment regardless of networking scheme.
