Foxboro Field Control Processor 270 (FCP270)

The Field Control Processor 270 is a distributed, optionally

fault-tolerant, field-mounted controller that performs process

control and alarming functions according to a user-defined

control strategy.

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).

FEATURES

 Performs regulatory, logic, timing, and sequential

control together with connected Fieldbus Modules (FBMs)

 Performs data acquisition and alarm detection

and notification

 Supports up to 32 200 Series FBMs - referring to

both Compact or standard types

 Supports up to 128 200 Series FBMs (Compact

or standard) with a Fieldbus Expansion Module

100 (FEM100)

 Supports up to 64 of the 100 Series FBMs

 No Fieldbus Communication Module is required

 Connects to the Foxboro Evo control network via

standard fiber optic 100 Mbps Ethernet

 Uses a rugged, die cast aluminum housing for

mounting in a non-vented field enclosure

 Can operate in Class G3 harsh environments

 Is CE certified for field mounting in enclosures

 Supports both the 2 Mbps or 268 Kbps HDLC

fieldbuses simultaneously with the FBI200

allowing connections to both 200 Series and

100 Series FBMs (affects the total number of

each type of FBM supported)

 Supports the extension of the 268 Kbps HDLC

fieldbus with the FBI100 to the 100 Series FBMs

 Offers unique, patented, fault-tolerant operation

using two control modules to greatly improve

reliability relative to other process controllers

 Uses versatile control algorithms and a wide

variety of FBMs to provide control capabilities for

a broad range of process applications

 Supports time synchronization using optional

external time from GPS satellites

 Offers on-line image update of a fault-tolerant

FCP270 without shutting down the process

 Uses soft letterbugs configurable via the

I/A Series® system Letterbug Configurator

running on a Pocket PC

 Supports self-hosting mode with I/A Series

software v8.4-v8.8 or Foxboro Evo™ Control

Core Services v9.0 or later.

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.
