segments.
The optional FBI200 can extend the 2 Mbps HDLC
fieldbus between 200 Series FBMs from 60 m (198 ft)
up to 305 m (1000 ft). As well, it can extend the
268 Kbps HDLC fieldbus between 100 Series FBMs
from 60 m (198 ft) up to 1830 m (6000 ft).
As with earlier generations of control processors, up
to 64 100 Series FBMs (including expansion
modules) attach to Fieldbus ports through Fieldbus
Isolators. (Up to 24 100 Series FBMs, excluding
expansion modules, can connect to each isolator.
However, the expansion modules are considered
100 Series FBMs in this “64 100 Series FBMs”
maximum discussed in this PSS.)
Available upgrade scenarios are available in Field
Control Processor 280 (FCP280) User’s Guide
(B0700FW).
FBI200 FIELDBUS ISOLATOR/FILTER
The FBI200 Fieldbus Isolator/Filter extends the length
of the 268 Kbps module Fieldbus from the FCP280
to 100 Series FBMs and similar competitive migration
modules up to 1830 m (6000 ft) over a twinaxial
Fieldbus cable. See Figure 2 on page 4.
It can also extend the 2 Mbps HDLC fieldbus to
200 Series FBMs up to 305 m (1000 ft).
For more information on the FBI200, refer to FBI200
Fieldbus Isolator/Filter (PSS 21H-2Y18 B4).
FIRMWARE UPGRADES WHILE ON-LINE
For fault-tolerant FCP280 modules, on-line image
upgrade replaces the executable image (operating
system) of a running FCP280 with a newer image
without having to shut down the equipment being
controlled by the FCP280.
TIME SYNCHRONIZATION, SOE, TDR/TDA
The Foxboro Evo Process Automation System
supports time synchronization using either an
externally maintained optional source of Universal
Coordinated Time (UTC) from GPS satellites or an
internal source using proprietary software. FCP280s
that receive time updates via the external time source
synchronize their FBMs to 1 ms. For more
information on time synchronization, refer to Time
Synchronization Overview (PSS 21S-1C2 B3).
Time stamping is used for alarm messages, values
sent to the historian, and the Sequence Of Events
(SOE) and Transient Data Recorder (TDR), and
Transient Data Analyzer (TDA) features.
SOE data are discrete points that are time stamped at the FBM, optionally to 1 ms, and sent to the workstation on a change basis. TDR/TDA data are analog or digital points that are time stamped at the FBM and sent to the workstation every 10 ms. These features are supported by client software in the workstation. For information on this new software, refer to Field Control Processor 280 (FCP280) Integrated Control Software (PSS 31S-3B3 B3). SOFTWARE CONTROL FEATURES The FCP280 performs regulatory, logic, timing, and sequential control, as well as data acquisition, alarm detection, and alarm notification. Process variables are controlled using time-proven algorithms (mathematical computations performing specific functions). The algorithms are contained in functional control blocks, which on-site process engineers configure to implement the desired control strategies. The versatility of the algorithms, coupled with the variety of FBMs available, provides control capabilities suited to a broad range of process applications. Control strategies ranging from simple feedback and cascade loops to highly sophisticated feedforward, nonlinear, and complex characterization control schemes are readily implemented. The FCP280 also supports the following features: Setting and reading the FCP280 letterbug via the buttons on the faceplate Alarm enhancements to function blocks: re-alarming on changes to alarm priority, re-alarming based upon a configurable time delay deadband, and alarm suppression based upon time Optional UTC external time synchronization Improved controller performance Optional self-hosting mode allows the FCP280 to start up and run, executing its configured control scheme using the checkpoint file stored in flash memory. This allows the FCP280 to boot itself with a valid control database even if its host workstation is not present. Support for high speed capabilities such as ladder logic, Motor Driven Actuator Controller (MDACT), and Distributed Proportional Integral Derivative functionality (DPIDA) DEVICES SUPPORTED The FCP280 supports the following devices on the 2 Mbps fieldbus: All Compact and standard 200 Series FBMs (FBM201, FBM202, and so forth), which can support many types of intelligent field devices, including those on FOUNDATION fieldbus, PROFIBUS, HART, and DeviceNet networks Field Device Systems Integrator (FDSI) modules Intrinsically Safe I/O Subsystem (ISCM) - refer to PSS 21H-2Y6 B4).
