The baseplates are backwards compatible with

existing I/O subsystems allowing for future expansion

without additional interface hardware and includes

the following:

 Primary and secondary 24 V dc power

connections

 Two Module Fieldbus connections (for A/B

Module Fieldbus daisy chain)

 Power/communication connection and field I/O

connection for each FBM

 DIP switch for baseplate identification

 A/B Module Fieldbus and optional time strobe

splitter/terminator connection

 Adding additional baseplates without removing

the system from service (requires redundant

Module Fieldbus).

The baseplates which support FBMs provide

increased overall system installation functionality by

providing unit increments of 2. 4. and 8 module

positions with various operational functionality in

combination with vertical and horizontal mounting.

Any FBM (except FBM232/233) can be removed

from a FBM-supporting baseplate without removing

or disturbing external field device wire terminations or

internal cable terminations or connections.

FCPs and FCMs require removal of wiring to the

control network.

Shielded twisted-pair cables for baseplate

interconnections are available in various lengths of

0.25 m (10 in) up to 60 m (198 ft). The maximum

twisted-pair cable length interconnecting all

baseplates is 60 m (198 ft).

Figure 1 shows selected vertical DIN rail mounted

baseplates. Horizontal DIN rail mounted baseplates

are available in similar styles as the vertical mounted

baseplates, but equivalents for each style are not all

available. Refer to PSS 31H-2SBASEPLT and

PSS 31H-2C200 B4 for additional information on the

remaining Standard and Compact 200 Series

baseplates.

200 SERIES BASEPLATE MODULE MOUNTING

The 200 Series Fieldbus Modules mount on

200 Series baseplates which have been specially

designed to support them (see Figure 1. only vertical

baseplates shown – also FBMs do not mount on the

FCP270-only, FCM-only, or FBI-only baseplates).

The baseplates shown in Figure 1 fasten to a

structurally supported non isolated DIN rail for

mounting inside or outside an enclosure. (As an

alternative to DIN rail mounting, a mounting plate can

be used for horizontal mounting of the 200 Series

baseplate on a 19-inch rack). These baseplates can

thus be mounted in small, distributed cabinets or in a

variety of other mounting configurations.

ENCLOSURES

Enclosures extend the design of the 200 Series

FBMs by providing a range of mounting options to

match application requirements.

The G-Series enclosures are floor-standing units

which accommodate 200 Series baseplates for

mounting FBMs, FEMs, FCMs, and CPs, and/or

termination assemblies or terminal blocks for

marshalling. Most are available for use in ordinary

(IP 43/54) or harsh (IP 55/65) rated environments.

Several product lines of metal enclosures are offered

with the standard 200 Series subsystem:

The 200 Series FBMs offer high resolution, high

accuracy, and repeatable design. The Sigma-Delta,

fast integrating converter used on the analog inputs

provides new readings as fast as every 25 ms,

suitable for high-speed regulatory control

applications. The analog inputs use a built-in

configurable moving average filter that efficiently

removes process noise and power line frequencies.

OPTIONAL REDUNDANCY

The standard 200 Series subsystem is optionally

available with total redundancy, for high reliability and

availability. Redundancy is available for; the power

supplies, the control network, the FCMs, the

FEMs(1)), the CPs, Modular Fieldbus cables between

baseplates, and certain FBM I/O module types.

Standard 200 Series I/O modules provide electrical and

data interfaces to a wide variety of industrial devices

and systems. Their rugged design permits installation in

harsh environments and allows the plant engineer to

reduce field wiring and installation costs. The modules’

high accuracy enables tight control for better process

quality.

OVERVIEW

The standard 200 Series subsystem innovative

equipment packaging, together with the integrated

use of Fast Ethernet networks with fiber optic cable

for communication between equipment domains,

permits local or remote distribution of your process

I/O points.

The standard 200 Series subsystem consists of a full

line of high performance Fieldbus Modules (FBMs),

along with the following integrally designed elements:

 Field Control Processor 280 (FCP280) and Field

Control Processor 270 (FCP270) – Similar in size

to the FBMs, this compact control processor

provides a control interface between the FBMs

and the Foxboro Evo Control network (hereinafter

referred to as the control network) and allows you

to locate the control processor in strategic plant

areas.

 Z-Module Control Processor 270 (ZCP270) – In

the Z-module form factor for use with 100 Series

FBM racks, this compact control processor

provides control operations for the FBMs and

allows you to locate the control processor in

strategic plant areas.

 Fieldbus Communications Modules (FCMs) –

Similar in size to the FBMs, these compact

modules provide a communication interface

between the FBMs and the ZCP270 via the

control network.

 FBI200 Fieldbus Isolator/Filter – Similar in size to

the FBMs, these compact, optional modules,

among other functions, extend the 268 kbps

Module Fieldbus between FCP280s/FCP270s

and 100 Series FBMs up to 1830 m (6000 ft)

over twinaxial cable.

 Standard Baseplates – These provide a

communications backplane and a solid base for

mounting the CPs, FBMs, and FCMs, allowing for

a variety of remote equipment mounting

configurations.

 Intrinsically Safe Baseplates (ISTA-BPs) –

Compatible with standard 200 Series baseplates,

the ISTA-BPs were co-developed with Pepperl

and Fuchs and provide an Intrinsically Safe

solution for 200 Series FBM applications.

 Enclosures – Several basic types provide various

levels of environmental protection and equipment

grouping for the 200 Series equipment.

The 200 Series FBMs provide full support for analog

measurement, digital sensing, and analog or discrete

control capabilities. The FBMs are rugged, high

performance distributed process I/O modules

designed for all process control tasks. Operating in

conjunction with the Foxboro Evo control processor

(FCP280. FCP270. or ZCP270), these FBMs provide

for process management and control of continuous,

batch and discrete control schemes.

REMOTE MOUNTING

The FCP270 flattens and simplifies the Foxboro Evo

Process Automation System architecture, which only

requires field enclosures plus workstations and

Ethernet switches. For more information on The

Foxboro Evo control network architecture, refer to

PSS 21H-7C2 B3.

The field-mounted FCP270 is an integral part of the

highly-distributed control network where controllers

are closely aligned to specific process units mounted

in close proximity to their I/O and the actual

equipment being controlled. Coordination between

process units takes place via a fiber optic 100 Mbps

Ethernet network.

The FCP270 is packaged in a rugged, die cast

aluminum housing that does not require venting due

to its efficient design. The FCP270 is CE certified,

and it can be mounted without expensive special

cabinets to prevent electronic emissions. The

FCP270 can be mounted in Class G3 harsh environments.

OVERVIEW

The Field Control Processor 270 (FCP270) is a

distributed, optionally fault-tolerant, field-mounted

controller module. The FCP270 performs regulatory,

logic, timing, and sequential control together with

connected Fieldbus Modules. It also performs data

acquisition and alarm detection and notification.

The FCP270 connects to the Foxboro Evo control

network via standard fiber optic 100 Mbps Ethernet.

The fault-tolerant version of the FCP270 consists of

two processor modules. These modules install in

adjacent FCP270 slots in a supported FCP270

baseplate for high speed communication between

the modules (see Figure 1).

The FCP270 is packaged in a rugged, die cast

aluminum housing that does not require venting due

to its efficient design. The FCP270 is CE certified,

and it can be mounted without expensive special

cabinets to prevent electronic emissions. The

FCP270 can be mounted in Class G3 harsh environments.
