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 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.

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.

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.

PRODUCT DESCRIPTIONS

Foxboro Evo system DCS FBMs for Bailey systems

allow migration to Foxboro Evo control, display, and

application products while retaining original process

terminations and field I/O wiring. All original process

I/O capability of the Bailey Controller Module (CM),

Analog Slave Module (ASM), Analog Output Module

(AOM), Digital Slave Module (DSM), Controller

Interface Slave Module (CIS), and Multifunction

Controller Module (MFC) functions is replaced by

direct Foxboro Evo control processor scanning and

control.

DCS FBMs plug directly into existing Bailey module

mounting units in place of Bailey controller and slave

module cards. The DCS FBMs pass process

measurement and output signals to and from a

Foxboro Evo control processor, which provides

control in place of the Bailey controllers. This saves

customers significant cost over a total system

replacement by preserving existing process

interfaces and wiring, and by minimizing process

downtime.

The following Foxboro Evo control processors can be

implemented:

 Field Control Processor 280 (FCP280)

 Field Control Processor 270 (FCP270)

 Control Processor 60 (CP60)

 Z-Module Control Processor 270 (ZCP270) with

FCM100E.

The FCP280 and FCP270 offer direct connection of

the DCS FBMs to the Fieldbus, while the ZCP270

connects to the FBMs through the FCM100E

modules. The CP60 requires redundant DCM10E or

DCM10Ef modules to communicate with the DCS

FBMs.

The FCP280. FCP270. ZCP270 and CP60 with the

DCM10E/Ef modules can be located in a nearby

existing enclosure or Foxboro Evo enclosure and the

fieldbus extended to connect the modules to the

Fieldbus Isolators (BFBI) located in a Bailey MMU.

FEATURES

Key features of the Foxboro Evo system DCS FBMs

are:

 DCS FBMs plug directly into an existing Bailey

module mounting unit (nest) to replace controller

and slave module cards

 Migration from proprietary DCS to a state-of-the

art open Foxboro Evo system

 Advanced Foxboro Evo system control with

single point of configuration

 More direct control performance than any

gateway device offers

 Single vendor service and supply.

FUNDAMENTAL PRINCIPLE

Foxboro® believes that it is only acceptable to

interface with competing manufacturers’ operating

systems at the lowest level, directly to field devices,

without communicating with proprietary buses or

components.

The Foxboro migration product offerings adhere to

this principle.

Foxboro Evo™ distributed control system (DCS) Fieldbus

Modules allow migration from Bailey® Network 90 and

INFI 90® process input and output (I/O) components

to a Foxboro Evo process control system.

OVERVIEW

The Foxboro Evo system DCS FBM family provides a

migration path from the Bailey systems process input

and output components to Foxboro Evo display and

supervisory functions. This can save significant cost

over total system replacement by preserving existing

process interface and wiring, and by minimizing

process downtime.

No additional communication devices are required.

No multi-vendor communication software licensing is

required. The DCS FBM family replaces the Bailey

controller and/or slave module devices. Once

integrated, the process is controlled

entirely by the advanced Foxboro Evo algorithm set.

Bailey DCS control devices are disconnected upon

migration, so there is no undesirable interaction

caused by the decommissioned system.

The Foxboro Evo DCS FBM product includes

appropriate connectors to enable integration of

original process signals to Foxboro Evo system while

keeping the field interface and wiring. It provides

access to all process signals connected to the Bailey

system by providing the connection between the

Field Termination Units (FTU) and the Foxboro Evo

system. All process signals become fully integrated

into the Foxboro Evo system. Process data is used

for operator display, history, alarming and control.

Operator functions and engineering configuration are

accomplished by the Foxboro Evo system. Because

all process values become part of the Foxboro Evo

system, all configuration data is maintained by the

system as native Foxboro Evo configurations.

This migration path provides plant operations with

the power and flexibility of the Foxboro Evo system.

All process values can be used plant wide for control,

display, history, alarming, and information

management from a single vendor source.

The DCS FBMs provide advanced 200 Series FBM

technology on an APACS+ module form factor. Each

DCS FBM plugs into the slot used by the replaced

APACS+ module and provides two rear connectors,

one of which mates to a connector on a local field

termination strip on the backplane of the

MODULRAC.

For marshalled termination assembly located in an

adjacent MODULPAC enclosure, the DCS Fieldbus

Module I/O connector mates to a field termination

cable connector mounted on the back of the

MODULRAC.

The following I/O module types are used in the

APACS+ system:

 Analog input module

 Analog multi-range input module

 Analog RTD input module

 Digital input module

 Digital output module

 HART® input module

 HART redundant input module

 Analog/digital/pulse input and analog/digital

output module, configurable point-by-point

 Analog/digital input and analog/digital output

module, configurable point-by-point

 Digital input/output, configurable point-by-point.

Each module type is replaced with an equivalent

Foxboro Evo DCS FBM module. All I/O wiring

connected to the I/O module termination strips

remain in place. Power is derived from the original

rack power supply. Table 1 lists the available DCS

Fieldbus Modules and the APACS+ modules they

replace.

APACS+ Subsystems

An FCP280. FCP270 or FCM100Et/FCM100E

baseplate is installed in the MODULPAC enclosure

with single or redundant modules. The baseplate has

a built-in Fieldbus termination assembly. The

I/O module power supplies and MODULRACs are

retained in the cabinet.

The MODULRACS, used to house I/O modules, are

reused to house the DCS FBMs. All termination

assemblies in the local, adjacent, and remotely

marshalled MODULPACs remain intact with their

termination cables and field wiring.

APACS+ I/O modules are removed from the

MODULRAC and replaced by a corresponding DCS

FBM that mates to the original power/signal

connector and termination cable connector on the

back of the MODULRAC. This DCS FBM provides

original I/O functionality of the process inputs and

outputs.
