Foxboro DCS Field Control Processor FCP280

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 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)
