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.

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 MESH control network via standard fiber optic 100 Mbps Ethernet

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

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 MESH 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).

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 MESH 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.
