Description
The Foxboro RH101AA is the FCP280 (Field Control Processor 280) module manufactured by Foxboro (Schneider Electric / Invensys) for the EcoStruxure Foxboro DCS (formerly Foxboro Evo and I/A Series).
As the central control engine in modern Foxboro automation systems, the RH101AA executes continuous, sequential, regulatory, and logic control algorithms. It communicates across high-speed Ethernet control mesh networks and manages high-density 200 Series Fieldbus Modules (FBMs) for real-time plant process control.

Core Features & Operating Capabilities
- High-Speed Control Execution: Executes regulatory loops, advanced logic sequences, and batch processing subroutines with fast execution scan times.
- Backward & Forward Compatibility: Integrates seamlessly into existing Foxboro I/A Series infrastructures, allowing modern FCP280 processors to replace legacy FCP270 or ZCP270 controllers while utilizing existing 200 Series FBM blocks.
- Fault-Tolerant Redundancy: Configurable in 1:1 redundant pairs that perform continuous, cycle-by-cycle state synchronization to ensure bumpfree failover if the active primary controller experiences a hardware or link fault.
- Gigabit Control Mesh Connectivity: Connects directly to the Foxboro high-speed fiber or copper Ethernet mesh network for rapid data throughput to workstation servers and neighboring controllers.
- Online Configuration & Hot-Swappable: Supports live module removal and replacement on operational baseplates without interrupting adjacent running loops or field communications.
