Foxboro Standard 200 Series Subsystem Overview

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.

FEATURES

Key features for the standard 200 Series subsystem

are:

 Allows you to locate control processor and field

input/output modules in strategic plant areas

 High performance Fieldbus Modules (FBMs)

 Enclosures to provide various levels of

environmental protection

 Optional redundant power

 Variety of modular mounting configurations

 High performance, high accuracy, fast updates

 Optional Intrinsically Safe baseplates for FBMs

 Reduced component count, for ultra-high

reliability and quality

 Optional redundancy

 Harsh (Class G3 - ISA S71.04) contamination

protection

 Distributed local and/or remote I/O

 Power security and alarming

 Electrical isolation and field device power

 High-speed system communication.

HIGH PERFORMANCE, HIGH ACCURACY,

FAST UPDATES

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.
