OVERVIEW

Fieldbus Communication Modules (FCMs) are fibre optic communication extenders that allow 200 Series fieldbus modules to be remotely mounted near plant processes.

FCM2F2 (RH914YZ), FCM2F4 (RH917JA) and FCM2F10 (RH916TQ)

Three models are available with nominal maximum substrate-to-substrate fibre optic cabling distances: up to 2 km (1.24 mi), 4 km (2.48 mi) and 10 km (6.21 mi) respectively.

FCMs are mounted in pairs on standard baseboards for redundancy. Non-redundant configurations require only a single FCM.

Fibre optic cabling is unaffected by electrical noise (EMI, RFI and lightning) and is a versatile and highly reliable means of extending signal communications.

It can be used in areas containing equipment such as rotating machinery, arc welders, etc. It can also be installed in cable bridges containing high voltage power lines, or in outdoor areas exposed to lightning hazards.

or outdoor areas exposed to lightning hazards. Its electrical isolation features protect against voltage differences and ground loops.

FCM Design

The FCM has a rugged extruded aluminium enclosure that provides physical protection for the circuitry.

Enclosures specifically designed for the installation of FBMs and FCMs provide varying degrees of environmental protection for the FCM, up to harsh environments (Class G), in accordance with ISA Standard S71.04.

The FCM can be removed/replaced from the base plate without power failure. six light-emitting diodes (LEDs) on the front of the FCM.

Six light-emitting diodes (LEDs) on the front of the FCM are used to indicate the status of network activity with the modular fieldbus and fibre-optic link, as well as the operational status of the FCM.

Figure 1 shows an example of a redundant configuration where the baseboards (containing the FCM) are connected point-to-point via fibre optic cable.

The cabling configuration shows a single fibre optic segment connecting two substrates. However, up to three fibre segments can be used to connect four baseboards (maximum).

The maximum fibre cabling distance between any two base stations is 10 km (using FCM2F10s (RH916TQ)).

The total fibre optic cabling distance (all cable segments) between base stations does not exceed 20 km (10.42 miles).

The Foxboro® brand Model IDP10 is an analogue output, two-wire d/p Cell® transmitter.

It provides accurate, reliable differential pressure measurement and transmits a 4 to 20 mA analogue output signal.

and converts it to a proportional pneumatic output signal for use with other pneumatic instruments or control valves.

As indicated by the “CE” marking on the product, it complies with applicable European Union directives.

Compact and easy to install

The small size and compact design of the E69F converter allows for easy connection to electrical and pneumatic interfaces.

It can be easily mounted on a surface, on a valve yoke or on a vertical pipe with a nominal DN 50 or 2.

Minimal influence on ambient atmospheric conditions

The design of the corona motor in the E69F converter allows a large clearance between the coil and the housing.

Normal atmospheric variations may cause corrosion and dust particles, but will not impede the operation of the mechanism as would be the case with voice coil type instruments.

Wide range of applications

Selectable input and output signals, different input ranges, and direct or reverse action make this converter easily adaptable to a wide variety of applications.

The choice of output signals makes the converter particularly suitable for valve applications.

OVERVIEW

The Compact HART Communication Output Interface Module (FBM215) contains eight channels of isolated output channels.

The Compact FBM215 supports any combination of standard 4 to 20 mA devices and HART devices, and is part of the Compact 200 Series I/O Subsystem, as described in the Compact 200 Series I/O Subsystem Overview.

The Compact FBM215 serves as a host for HART-communicating field devices, allowing the Foxboro Evo system to request and receive two digital telegrams per second from each field device.

The Telegram Pass-Through feature can be used to support HART generic, common, and device-specific commands, but does not support burst communication modes.

These commands are implemented through the Intelligent Field Device Configurator (IFDC – see Intelligent Field Device Configurator FoxCom for details) and the HART protocol.

The compact FBM215 provides an isolated power supply for each channel.

When connected to the appropriate TA, the Compact FBM215 provides the functionality previously provided by the 100 Series FBM I/O subsystem.

TAs support the functional HART devices of the 100 Series FBM37 when the FBM37 is used with the following devices

The 130M Series Pnuematic controllers offer manual setpoint adjustment and are the standard controller in the Foxboro® 130 Series.

All Foxboro® 130 Series controllers are designed for high-density control room installations.

These devices are ideally suited for applications where precise control is critical to skilled process management.

The 130M Series is essentially the same as the 130P and 130F Series with the exception of the following features:

130P Series: Has setpoints that are pneumatically modified by remote signals.

130F Series: Remote/local switching to support manual or pneumatic modification of setpoints.

Designed for high-density control room installations, these controllers are suitable for any situation where precise control is required for efficient process management.

The basic controller is the 130M series with manual setpoint adjustment. 130P series is similar to the 130M, but the setpoint can be adjusted pneumatically via a remote signal.

The 130F series is similar to the 130M but includes a remote/local switch for manual or pneumatic setpoint adjustment.

Large Eye-Catching Display

The visibility and legibility of the large, brightly colored pointer located directly behind the clear vertical scale has become the benchmark against which other display concepts are judged.

The system provides a continuous full-scale display of all variables, an effective indication of controller deviations, and easy scale changes without tools.

Separate automatic and manual control units

Both the automatic and manual control units can be disassembled without disrupting the process.

This design feature avoids costly downtime for servicing the controller.

Completely Unbalanced and Bufferless Transmission

The 130 Series controllers utilize the “integral balancing” method for bufferless transfer. After transfer, the controller simply responds at the integral (reset) rate that

This eliminates any error between setpoint and measurement. In addition to providing easy, unbalanced and unbuffered transmission, this solution preserves the setpoint.

Simple and cost-effective installation

Up to 10 instruments can be accommodated in a multi-unit rack. All air connections are made when the controller is installed in the rack.

Piping costs are minimized as each rack has its own integrated air supply header and individual air shutoff valve.

Easy Maintenance

The 130 Series utilizes a unique pneumatic circuit board that greatly enhances the sophistication of the pneumatic control system. This board eliminates many of the piping and connections found in other controllers.

All components are located on one side of the board and are easily accessible by sliding back the cover on one side.

OVERVIEW

The FBM204.0 to 20 mA Input/Output consists of four 20 mA dc analog input channels and four 20 mA dc analog output channels.

Each input channel accepts an analog sensor input or a self-powered 20 mA supply.

Each output channel drives an external load to produce a 0 to 20 mA output.

The inputs/outputs are electrically isolated from other inputs/outputs on channel and ground.

The FBM204 performs the signal conversion required for electrical input interfaces/output signals from field sensors to an optional redundant fieldbus.

The FBM204 performs analog I/O applications that provide configurable options for the following functions: conversion time,

Fail Safe Configuration (Hold/Return) and Analog Output Fail Safe Return Data (on a per channel basis).

The Fieldbus Module (FBM) can alternatively perform the fast control loops in which Distributed PIDA (DPIDA) applications provide operation.

The FBM204 is electrically compatible with standard HART signals.
