FCP280 RH924YA servo controller module Foxboro

Description

When supporting 200 Series and 100 Series FBMs, each Fieldbus port (PIO channel) is dedicated to supporting either a 268 Kbps HDLC fieldbus (for 100 Series FBMs) or a 2 Mbps HDLC fieldbus (for 200 Series FBMs) – not both. For connections to 100 Series FBMs over 60 m (198 ft), an FBI200 pair is required to extend communications up to 1830 m (6000 ft). See Figure 2 below. To connect a Fieldbus port to a 268 Kbps HDLC fieldbus directly, the Fieldbus splitter (RH928CV) provides a connector for any Fieldbus port on the FCP280 baseplate, and two Termination Cable Assembly (TCA) termination blocks for the twinaxial cabling from the 100 Series FBMs.

The FCP280 can also communicate with serial and Ethernet devices, such as PLCs, via Field Device System Integrators. This allows you to connect to new device interfaces without any changes to the controller software. To estimate the FCP280’s processor load, refer to Field Control Processor 280 (FCP280) Sizing Guidelines and Excel Workbook (B0700FY).

FCP280 modules connect to a pair of fiber or copper adapters (see Figure 4) which each connect to one Ethernet switch in The Mesh control network. The FCP280 baseplate passes inbound traffic from either of the two switches to both FCP280s, and pass outbound traffic from the primary FCP280 module to either switch.

The FCP280 simplifies the Foxboro Evo Process Automation System architecture, maintaining control while only requiring housing (via field enclosures), host workstations with Foxboro Evo Control Core Services v9.0 or later, and Ethernet switches for communication via The Mesh control network architecture, described in PSS 21H-7C2 B3. The field-mounted FCP280 is an integral part of the highly-distributed control network where controllers are closely aligned to specific process units mounted in close proximity to their I/O and the actual equipment being controlled. Coordination between process units takes place via a fiber optic 100 Mbps Ethernet network.
