Foxboro™ DCS Field Control Processor 280 (FCP280) Function

Function

- Performs regulation, logic, timing, and sequence control with connected Foxboro DCS Fieldbus Modules (FBMs)

Foxboro DCS Fieldbus Module (FBM)

- Performs data acquisition, alarm detection and notification

- Supports up to 128 compact or standard 200 series FBMs, 128 100 series FBMs, or up to 128 100 series FBMs

or a combination of up to 128 100 Series FBMs and 200 Series FBMs,

No fieldbus communication module required (up to 64 100-series FBMs per fieldbus allowed)

(up to 64 100-series FBMs per fieldbus per PIO bus/substrate port)

- Supports fieldbus expansion without fieldbus expansion modules

- Supports self-hosted mode, allowing the FCP280 to boot itself up with

an active control database even in the absence of a host workstation.

Even if the host workstation is not online, the FCP280 can start up with a valid control database.

However, the control functions cannot be edited.

- Provides unique, patented fault-tolerant operation using two control modules,

which greatly improves reliability compared to other process controllers.

- Provides an online image upgrade (OLUG) of the fault tolerant FCP280.

- Enhanced Online Image Upgrade (EOLUG) of the Fault Tolerant FCP280

 can be performed while the process is running.

This form of upgrade helps to prevent any significant impact on the local control process.

- Provides CP overload protection to notify the operator when the FCP280 is reaching its performance limits

- Liquid crystal display (LCD) shows letter errors as well as real-time roles and statuses

- Connects to the Foxboro DCS control network via standard fibre optic or copper 100 Mbps Ethernet cable

- Rugged die-cast aluminium enclosure for installation in unventilated field cabinets

- Operates in G3 rated harsh environments

- CE certified for field installation in cabinets

- Each fieldbus port on the standard FCP280 baseboard supports a dedicated 2 Mbps or 268 Kbps HDLC fieldbus port

- Provides control capability for a variety of process applications using versatile control algorithms and a variety of FBMs

- Supports time synchronisation using optional external time from GPS satellites

Using soft letter blocks, the FCP280 can be configured via pushbuttons on the panel.

- Optional dual cable substrate allows use of separate cables for each ‘A’ and ‘B’ buses

Remote Installation

The FCP280 simplifies Foxboro DCS system architecture by requiring only

the enclosure (via field enclosure) while maintaining control,

host workstation with Control Core Services v9.0 or higher, 

and an Ethernet switch to communicate through the control network structure.

The field-installed FCP280 is part of a highly distributed control network

In this network, the controllers work closely with specific process units

mounted in close proximity to their I/O and the actual controlled equipment.

The process units are coordinated via a fibre optic 100 Mbps Ethernet network.

The FCP280 and its network adapters are encased in a robust die-cast aluminium

enclosure that requires no ventilation due to its efficient design.

The FCP280 and its network adapter are CE certified and can be installed

without the need for an expensive dedicated cabinet, helping to protect against electronic radiation.

The FCP280. network adapters and backplane can be installed in G3 rated harsh environments.
