Foxboro FCP280 Field Control Processor

Technical Specifications Module Type: High‑Performance Field Control Processor Processor Architecture: ARM‑based Memory: 128 MB SDRAM, 128 MB Flash memory Max Control Blocks: 8000 configurable control blocks, 16000 blocks per‑second processing throughput Fieldbus Interface: Four HDLC fieldbus links, 2 Mbps for 200‑series FBM Maximum FBM Capacity: Up to 128 FBM fieldbus modules Control‑Network Interface: Redundant copper / fiber Ethernet adapters (baseplate‑mounted) Operating Power: 24 VDC, typical consumption below 11 W for single module Operating Temperature: −40 °C to +70 °C Storage Temperature: −40 °C to +85 °C Relative Humidity: 5%‑95%, non‑condensing Mounting: Dedicated FCP280 baseplate installation Certifications: CE, G3 corrosive‑gas environment rated industrial controller compliance

Functional Features High‑throughput real‑time control‑block execution for complex process‑control and interlock‑logic tasks. Fault‑tolerant redundant‑pair deployment realizes bumpless master‑standby switchover. Four HDLC fieldbus links support direct access up to 128 FBM modules without extra expansion hardware. Supports both copper and fiber redundant Ethernet communication adapters. Compatible with FCP270 configuration database for convenient system‑upgrade migration. Configuration data is persistently stored in on‑board flash memory against power‑failure events

Application Scenarios Used as core control hardware for new‑build or upgraded petrochemical, chemical and power‑plant Foxboro Evo DCS systems. Executes large‑scale closed‑loop regulation, sequence control and safety interlock logic for complex industrial process units.

Structural Characteristics Rugged die‑cast aluminum controller housing. Gold‑plated bottom connector for electrical connection with dedicated FCP280 baseplate. Baseplate supports plug‑gable copper or fiber Ethernet network adapters. Front‑panel LED indicators for power, master‑standby state, fieldbus and network‑link working status.

Working Principle After power‑on, FCP280 loads control‑configuration database stored in flash memory. It communicates with FBM I/O modules via four HDLC fieldbus links, collects field‑process‑variable data.

Installation Requirements Mount dedicated FCP280 baseplate on standard 35 mm DIN‑rail inside control cabinet. Install required copper or fiber Ethernet adapters onto baseplate. Insert FCP280 module onto baseplate and lock mechanical buckle.
