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.
