FOXBORO FCP280 RH924YA Field Control Processor

The EcoStruxure™ Foxboro™ DCS Field Control Processor 280 (FCP280) is a distributed, optionally fault-tolerant, field-mounted controller module. The FCP280 performs regulatory, logic, timing, and sequential control together with connected Foxboro DCS Fieldbus Modules (FBMs). It also performs data acquisition and alarm detection, and notification. The FCP280 connects to the Foxboro DCS Control Network via standard fiber optic or copper 100 Mbps Ethernet cables from network adapters installed on its baseplate.

• FCP280: RH924YA

• FCP280 Horizontal-Mounted Baseplate: RH924YL

• FCP280 Vertical-Mounted Baseplate: RH924YF

• FCP280 Dual Cable Baseplate: (Horizontal or Vertical mount) RH100JX

• Fiber Adapter: RH924WA

• Copper Adapter: RH924UQ

• Splitter Adapters:

   ◦ Twinaxial Fieldbus Splitter: RH928CV

   ◦ Redundant Module Fieldbus Cable Adapter:

     RH924ZJ - For use when the FCP280 is in the middle of a 200 Series baseplate chain

     RH928CY - Enables the use of redundant module Fieldbus cables between baseplates to split and terminate the Modular Fieldbus and optional time strobe signals

   ◦ Time Strobe Adapter: RH924ZQ

The number of 200 Series and 100 Series FBMs that an FCP280 can support varies depending on the types of FBMs used:

• 200 Series FBMs exclusively used with FCP280 - Each Fieldbus port on the FCP280 baseplate can connect to a baseplate chain with up to 32 Compact or standard 200 Series FBMs per chain via the 2 Mbps HDLC fieldbus for up to 128 modules.

• 200 Series and 100 Series FBMs (dual baud configurations) used with FCP280. The FCP280 can support a total of 128 100 Series FBMs (Y-module) or competitive devices (such as Foxboro DCS system migration FBMs) in one or more baseplate chains, with the remainder of the FCP280's 128 module limit being 200 Series FBMs, depending on the Fieldbus loading of the FCP280. For example, an FCP280 could support 64 100 Series FBMs and 64 200 Series FBMs (as 64 + 64 = 128). Main and expansion FBMs are considered as two FBMs for counting purposes. As well, no more than 64 100 Series FBMs are allowed on each PIO channel/baseplate port.

The FCP280 has a liquid crystal display (LCD) on its faceplate, which displays various status and identification information:

• The first line typically displays the FCP280's letterbug and role (Primary/Shadow/ Single)

• The second line displays the FCP280's part number, hardware revision information, manufacturing date, OS version, and its status on the Control Network
