FOXBORO FDC280 RH101FQ DCS Modules

Overview

The Foxboro ™ DCSField Device Controller 280 (FDC280) is a distributed, optionally fault-tolerant, field-mounted controller that performs process control and alarming functions according to a user-defined control strategy, as well as providing direct field device integration without the need for additional Foxboro DCS Fieldbus Modules (FBMs). The primary purpose of the Field Device Controller 280 (FDC280) is device integration, including interfacing Ethernet and Serial field devices, accessing data in those devices for display, historization, and performing control tasks. The FDC280 performs regulatory, logic, timing, and sequential control internally. It also performs alarm detection and notification.

The FDC280runs adual-core CPU to provide two computational environments for the FDC280. Core 1 (Control Core) runs the FDC280’s control software and Foxboro DCS Control Network communications software. Core 2 (I/O Core) runs additional features, in this case, the device integration software. The FDC280communicates directly with field devices that support the protocols listed in these PSSs: 

 • ModbusClient TCP Driver for Field Device Controller 280 (PSS 41S 3FDCMBDV) 

 • ModbusClient RTUSerial Driver for Field Device Controller 280 (PSS 41S 3FDCMBRT) 

 • Triconex System Access Application Driver for Field Device Controller 280 (PSS 41S-3FDCTSAA) 

 • OPCUAClientDriver for Field Device Controller 280 (PSS 41S-3FDCOPC) 

 • EtherNet/IP Scanner Driver for Field Device Controller 280 (PSS 41S 3FDCIPDR) The FDC280connects to the Control Network via standard fiber optic or copper 100 Mbps Ethernet cables from network adapters installed on its baseplate. The FDC280requires a host workstation with Foxboro DCS Control Core Services software v9.3 or later.

The FDC280baseplate also includes the following types of connectors:

• TwoCat5RJ-45connectors for Time Strobe connections that allow time strobe cables to connect directly to the baseplate without the need for Time Strobe Adapters. 

• Two10/100Mbpsor1GbpscopperCat5eorCat6Ethernet RJ-45 connectors for Ethernet connections to supported field devices (via customer-supplied Ethernet switches).

FDC280 Ethernet Network Configurations

The FDC280supports various Ethernet network configurations to connect with supported field devices. The FDC280 can connect directly to field devices with Ethernet I/O, or to field devices with Serial I/O via a protocol-specific gateway that performs the Ethernet-to-Serial I/O bridging.

FDC280 Serial Network Configurations

The FDC280hasfour Serial ports. Each port can be individually configured for RS 232, RS-422, or RS-485. In non-redundant configurations, a simplex FDC280 is used for interfacing single ported field devices. In redundant configurations, the fault tolerant FDC280s (Left/Right) can both interface dual-ported and single-ported field devices (RS-232 via a Y cable). The FDC280 supports up to 128 RS-485 field devices distributed over its four ports. On a port configured for RS-485 protocol, the maximum number of devices supported is 32.
