The EcoStruxure™ Foxboro™ DCS Field Control Processor 280 (FCP280) is a distributed, optionally fault-tolerant, field-installable controller module.

The FCP280 performs regulation, logic, timing, and sequence control with connected Foxboro DCS Fieldbus Modules (FBMs).

It also performs data acquisition, alarm detection, and notification.The FCP280. through a chassis-mounted network adapter, is

connects to the Foxboro DCS control network with standard fibre optic or 100 Mbps copper cable (see figure below).

The FCP280 requires Foxboro DCS Control Core Services Software v9.0 or higher.

A system with the FCP280 and this software is called an EcoStruxure Foxboro DCS Process Automation System.

– 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

– 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

The FCP280 performs regulation, logic, timing and sequence control, as well as data acquisition, alarm detection and alarm notification.

Acquisition, alarm detection and alarm notification. Process variables are controlled using time-proven algorithms (mathematical calculations that perform specific functions).

These algorithms are contained in functional control blocks that are configured by the field process engineer to implement the desired control strategy.

The versatility of the algorithms, combined with the variety of available FBMs, provides control capabilities suitable for a wide range of process applications.

From simple feedback and cascade loops to highly complex www.cniacs.com feed-forward, non-linear and complex characteristic control schemes, a variety of control strategies can be easily implemented.

The FCP280 also supports the following functions:

– Setting and reading FCP280 beacons via panel pushbuttons

– Function Block Alarm Enhancement:

Re-alarm on alarm priority change

Re-alarm on configurable time-delayed dead zones and suppress alarms based on time

– Optional UTC external time synchronisation

– Improved controller performance

– The optional self-hosted mode allows the FCP280 to boot up and run, executing configured control schemes using checkpoint files stored in flash memory.

This allows the FCP280 to start up with an efficient control database even if the host workstation is not present.

– Supports high-speed functions such as ladder logic, Motor Drive Actuator Controller (MDACT) and Distributed Proportional Integral Derivative Function (DPIDA)

Liquid Crystal Display (LCD)

The FCP280 has a liquid crystal display (LCD) on the panel that displays a variety of status and identification information, including

Status and identification information:

– The first line typically displays the letter number and role (Master/Shadow/Single) of the FCP280.

– The second line shows the FCP280’s part number, hardware revision information, date of manufacture, operating system version, and its status on the control network.

LED Indicators

The light-emitting diodes (LEDs) on the front of the FCP280 module provide a visual indication of the

– FCP280 operating status

– Transmit/receive communication activity on the four extended fieldbus channels (Fieldbus A and B on each channel) LEDs on copper or fibre optic network adapters provide visual indication of the following

– Internal and external power supply health status

– Communication activity with the control network A and B links and the FCP280

WIDE SELECTION OF MEASURING ELEMENTS

Invensys Foxboro offers the widest variety of element constructions and ranges in the industry. This versatility enables the 43AP Series Pneumatic Indicating Controllers to be applied to virtually any process.

WIDE CHOICE OF CONTROL MODES

On-off, proportional, proportional plus derivative, proportional plus integral (reset), proportional plus integral plus derivative, differential gap, and www.cniacs.com automatic shutdown actions are available.

BROAD RANGE OF INTEGRAL (RESET) AND DERIVATIVE ADJUSTMENTS

The integral unit has the complete range from 0.01to 50 minutes, and the derivative unit from 0.05 to 50 minutes.

VARIETY OF OPTIONS

These controllers are available with an extensive list of optional features. Among these are internal bumpless automatic-manual transfer stations (two types), “batch” function, remote pneumatic set point, Type 70 electric contacts, and control valve mounting.

ACCURACY UNAFFECTED BY MOUNTING STRESSES

Both the control unit and the measurement element are mounted on a rigid steel plate. Thus, these components are isolated from case stresses due to mounting, and dependable accuracy is ensured.

POWER FAILURES DO NOT INFLUENCE PROCESS-DRIVEN INDICATION

A power failure and the likely subsequent loss of supply pressure do not influence the process-driven indication.

WEATHERPROOF CONSTRUCTION

A glass fiber reinforced case and a gasketed door with a shatterproof polycarbonate window meet IEC IP53 and provide the environmental protection of NEMA® Type 3.

VERSATILE MOUNTING

Instruments may be mounted in a panel, on a flat surface, on a INTERNAL BUMPLESS AUTOMATIC-MANUAL TRANSFER STATION

This option provides bumpless-balanceable transfer between automatic and manual control by simple 2step procedure. Accidental transfer is avoided because the door must be opened to gain access to the transfer station.
