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).

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.
