PRODUCT DESCRIPTIONS

The Foxboro Evo migration strategy replaces the

APACS+ process control system with a 2 Mbps

Fieldbus connection to a Field Control Processor

(FCP280 or FCP270), provides a module-for-module

replacement of I/O modules, but leaves the original

process interface wiring and cabinets in place.

To replace the APACS+ control and I/O modules

mounted in MODULRAC, SIXRAC or UNIRAC

assemblies, the APACS+ migration consists of new

Foxboro Evo DCS FBMs, FCP280/FCP270 and

baseplate. The baseplate supports either a single

FCP280/FCP270 module or a pair of fault-tolerant

FCP280/FCP270 modules. The FCP280/FCP270

provides the control algorithms and interface

between the FBMs and the 100 Mbps/1 Gbps

Ethernet control network. This allows migration to

Foxboro Evo control, display and application

products while retaining the original process

termination and field I/O wiring. All original process

I/O capability of the APACS+ module functions is

replaced by FBMs and direct Foxboro Evo control

processor scanning and control. For more

information on the FCP270. refer to

PSS 21H-1B9. For more information on the FCP280.

refer to PSS 31H-FCP280.

New DCS FBMs plug directly into existing

MODULRACs, SIXRACS or UNIRACs in place of

APACS+ I/O modules.

The Fieldbus connects the DCS FBM subsystem to

the FCP280. FCP270 or ZCP270. I/O from the

subsystem is connected to the control strategy using

standard Foxboro Evo system I/O type blocks. The

DCS FBMs pass process measurement and output

signals and digital I/O signals to and from the control

processor.

All process signals are fully integrated into the

Foxboro Evo system, allowing direct Foxboro Evo

system monitoring and control of the process.

Migration using theFCP280. FCP270 or

FCM100Et/FCM100E and baseplate is accomplished

using the DCS Fieldbus Module Migration Kit

(P0922TL).
