INTRODUCTION

The G62 and G72 enclosures are specifically designed for housing Tricon system

chassis and modules, DIN rail mounted Triconex termination devices and customer

-supplied terminal blocks for marshalling. These enclosures are available as vented

enclosures. They can be configured with:

• Up to two Tricon system chassis

• Two vertical DIN rails for mounting of Triconex termination devices. One rail may

be used to mount terminal blocks for marshalling.

The G62 and G72 enclosures are free-standing, floor mounted units with an IP 43

rating for location in mild (ordinary) environmental areas. Versions are available

with optional EMC compliance.

NOTE

In regions that require EMC compliance, you must order the EMC compliance option

if Tricon modules SMM or SRXM will be installed in a chassis in this enclosure.

Without these modules, these enclosures already fulfill the requirements for EMC

compliance.

BASEPLATE IMPLEMENTATION

A grouping of up to four baseplates per FCM (pair)

can be connected together, for mounting of up to 32

modules (30FBMs and 2 FCMs). Multiple groups of

baseplates can be connected to the Ethernet trunk

Fieldbus, either directly (via Ethernet connectors) or

through one or more multiport fiber optic converters

(hubs). (Refer to PSS 21H-2W1 B3 for information on

the various DIN rail mounted FBM subsystem

communication topologies). Module Fieldbus

interconnection between baseplates is made by

shielded twisted-pair cable for local configurations

and/or by fiber optic cable for remote configurations.

Using fiber optic topologies (refer to

PSS21H-2W1B3), baseplates can be separated up

to 10 km (6.2 mi).

Figure 1 shows baseplate implementation using only

shielded twisted-pair cable connections. This

configuration is used when the four (maximum)

baseplates are mounted in the same general location.

Using shielded twisted-pair cable, the baseplates can

be interconnected up to 60 m (196 ft) total cable

distance. Shielded twisted-pair cables are available in

lengths of 0.25 m (10 in), 1 m (3.3 ft), 3 m (9.9 ft), 5 m

(16.5 ft), 10 m (33 ft), 20 m (66 ft), 30 m (99 ft) and

60m (198 ft), allowing placement of the baseplates

(up to four in a group) in one or more enclosures.

BASEPLATE MOUNTING

The baseplate is available in two basic mounting

configurations — horizontal DIN rail mount or vertical

DIN rail mount. Either of these configurations can be

employed internal to, or external to an enclosure;

however, in all cases the DIN rail must be amply

supported, whether by means of metal braces, a

backplate, or a supporting wall.

In addition to DIN rail mounting of the baseplate, a

mounting kit is available for mounting the baseplate

horizontally in a standard, 483 mm (19 in) rack. The

kit provides a 25.4mm (1 in) mounting depth, to meet

clearance requirements at the front of the 19-inch

rack.

Figure 2 shows how baseplate implementation can be

extended using fiber optic cabling. In this

configuration, up to three module Fieldbus segments

can be fiber optic, allowing the baseplates to be

dispersed over a wider area. The FCM2Fs provide

three different fiber optic cabling distances between

baseplates: 2km (1.24 mi), 4 km (2.48 mi), or 10km

(6.2 mi). Refer to PSS21H-2Y3 B3 for additional

information on baseplate implementation using this

configuration.

The DIN rail mounted Fieldbus Module baseplate

provides a convenient, secure facility for the mounting

of DIN rail mounted Fieldbus Modules (FBMs) and

Fieldbus Communications Modules (FCMs). Its eight

mounting positions can accommodate up to eight

FBMs or a combination of FBMs and FCMs.The

baseplate also provides the necessary connectors for

redundant power, redundant module Fieldbus, and

termination cables.

PLUG-IN MODULES

The DIN rail mounted FBMs accommodated by the

baseplate are compact, plug-in modular assemblies

used to interface field devices with the host control

station. The FCMs, having the same form factor as

the FBMs, perform signal interface functions.

For example, FCM10Es are used to interface the

Ethernet trunk Fieldbus with the 2 Mbps module

Fieldbus, and FCM2Fs are used for fiber optic

communications extensions between baseplates. The

FBMs and FCMs plug onto the baseplate by means

of their two, 48-pin connectors, and each is fastened

in place by two screws.

Introduction

The Foxboro I/A Series® system, as introduced in 1987 was 

claimed to be ahead of its time. Fast forward to the current 

generation of automation technologies and Emerson is the clear 

choice to move your business forward for decades to come. 

Aging I/A Series systems need to be modernized and Emerson 

is committed to making your transition to a DeltaV™ system, 

smooth, low risk and cost effective. From early modernization 

planning to long term lifecycle care, Emerson has provided 

industry leading solutions and service to complete more than 

130 projects replacing Foxboro I/A Series systems. Partner with 

us for your transformation to a digital architecture, resulting in 

improved business performance and competitive edge.

Why Choose Emerson As Your 

Automation Partner?

Modernization projects are different. They require knowledge 

of both old and new technology and have fewer degrees of 

freedom than greenfield projects, i.e. space, time, and budget. 

The transition project will impact operations, often must be 

done during short shutdown windows and has the potential  

to put production at risk.

This puts a premium on risk reduction, flexibility,  

and capital efficiency.

OVERVIEW

The I/A Series system DCS Fieldbus Modules (FBMs) 

are for migration of APACS+™ automation systems 

manufactured by Siemens® Energy & Automation, 

Inc. and Moore Products Co. The FBMs plug directly 

into an existing electronic nest to replace process 

input and output modules.

The I/A Series system DCS FBM family provides a 

migration path from APACS+ process I/O 

components to I/A Series display and supervisory 

functions. No additional communication devices are 

required. No multi-vendor communication software 

licensing is required.

The I/A Series system DCS FBM family replaces the 

APACS+ I/O modules. Once integrated, the process 

is controlled entirely by the advanced I/A Series 

algorithm set.

The I/A Series system DCS FBM product includes 

connectors to enable integration of original process 

signals to I/A Series systems while keeping the field 

interface and wiring. It provides access to all process 

signals connected to the APACS+ system by 

providing the connection between the Field 

Termination Assemblies (FTAs) and the I/A Series 

system. All process signals become fully integrated 

into the I/A Series system through the use of process 

data for operator display, history, alarming and 

control.

Operator functions and engineering configuration are 

accomplished by the I/A Series system at any 

I/A Series operator workstation. Because all process 

values become part of the I/A Series system, all 

configuration data is maintained by the system as 

native I/A Series configurations.

This migration path provides plant operations with all 

the power and flexibility of the I/A Series system.

FUNDAMENTAL PRINCIPLE

Invensys believes that it is only acceptable to 

interface with competing manufacturers’ operating 

systems in two ways:

 Through high level public gateways

 At the lowest level directly to field devices without 

communicating with proprietary buses or 

components.

The Invensys migration product offerings adhere to 

this principle.

I/A Series® system Field Control Processor 270 (FCP270)

modules mounted on a baseplate and distributed control

system (DCS) Fieldbus Modules replace the APACS+ Control

and I/O modules and connect existing field devices to the I/A

Series system via a 2 Mbps HDLC Fieldbus and high-speed

Ethernet network

FEATURES

 Migration from proprietary DCS to a

state-of-the-art open I/A Series system

 Advanced I/A Series control with a single point of 

configuration

 More direct control performance than any 

gateway device could offer

 Cost savings over total system replacement by 

preserving the existing process interface and 

wiring and minimizing process downtime

 Single vendor service and supply.

FoxView WINDOW

The FoxView window contains the following optional

features:

 A user-configurable Menu Bar for accessing

displays, configurators, and other applications as

specified by the environment

 A user-configurable Display Bar of 18 named

display buttons or eight “thumbnail” sized mini

display buttons for directly accessing process

displays, or launching applications

 An Alarm Bar with system and process buttons,

indicating system and process health

 A Message Bar with a drop-down list of the most

recent 25 messages; and display of the current

date and time

 A Status Bar, indicating the current display name,

current operating environment, Operator Action

Journal logging name, printer logging name, and

Historian name.

USER ENVIRONMENTS

A collection of programs, utilities, and displays

related to user tasks is provided for each of the

following: process operator, process engineer, and
