Migration with FCP280 and DCS FBMs

The Field Control Processor 280 (FCP280) is a

distributed, field-mounted controller module that

supports up to 128 DCS FBMs – 32 per HDLC

fieldbus. The FCP280 connects to the control

network via optionally redundant 100 Mbps Ethernet

fiber optic cables and Ethernet fiber switches. The

FCP280 is an optionally fault-tolerant controller that

communicates with connected DCS FBMs to

perform data acquisition and control using Foxboro

Evo control algorithms.

The FCP280 mounts in a 2-position baseplate that

supports a single module or a fault-tolerant module

pair. The baseplate accepts only FCP280 modules.

The FCP280 connects to an optionally redundant

2 Mbps HDLC I/O Fieldbus for communications to

the DCS FBMs and provides galvanic isolation

between the 100 Mbps Ethernet Fieldbus and the

2 Mbps local Fieldbus.

FCP280 modules connect to a pair of copper or fiber

optic network adapters that connect to Ethernet

switches in a redundant control network. The

network adapter pair mounts to the FCP280

baseplate.

To support redundancy, a pair of FCP280s must be

used for each DCS FBM grouping. In non-redundant

configurations, only a single FCP280 is required for

each grouping.

The maximum total cable length for the 2 Mbps

Fieldbus is 60 m (198 ft) within a grouping.
