WIDE CHOICE OF CONTROL MODES

On-off, proportional, proportional plus derivative, proportional plus integral (reset), proportional plus integral plus derivative, differential gap, and www.cniacs.com automatic shutdown actions are available.

BROAD RANGE OF INTEGRAL (RESET) AND DERIVATIVE ADJUSTMENTS

The integral unit has the complete range from 0.01to 50 minutes, and the derivative unit from 0.05 to 50 minutes.

VARIETY OF OPTIONS

These controllers are available with an extensive list of optional features. Among these are internal bumpless automatic-manual transfer stations (two types), “batch” function, remote pneumatic set point, Type 70 electric contacts, and control valve mounting.

ACCURACY UNAFFECTED BY MOUNTING STRESSES

Both the control unit and the measurement element are mounted on a rigid steel plate. Thus, these components are isolated from case stresses due to mounting, and dependable accuracy is ensured.

POWER FAILURES DO NOT INFLUENCE PROCESS-DRIVEN INDICATION

A power failure and the likely subsequent loss of supply pressure do not influence the process-driven indication.

WEATHERPROOF CONSTRUCTION

A glass fiber reinforced case and a gasketed door with a shatterproof polycarbonate window meet IEC IP53 and provide the environmental protection of NEMA® Type 3.

VERSATILE MOUNTING

Instruments may be mounted in a panel, on a flat surface, on a INTERNAL BUMPLESS AUTOMATIC-MANUAL TRANSFER STATION

This option provides bumpless-balanceable transfer between automatic and manual control by simple 2step procedure. Accidental transfer is avoided because the door must be opened to gain access to the transfer station.

The FBM233 connects to an Ethernet switch or hub to communicate with one external device or up to 64 external devices.

The combination of a pair of modules provides redundancy at the fieldbus module (FBM) level.

In this configuration, one FBM233 is the master and the other is the tracking module.

Input points on the control station are updated from device input points received on the network connected to the master.

Device output points (depending on the I/O driver) are written by both the master and the trace module.

If the I/O driver detects a problem (e.g. any device loses its heartbeat), a role switch is automatically performed, or the user can switch roles at any time via the SMDH.

Functional Features

Key features of the FBM233 include

– Redundant 10 Mbps or 100 Mbps Ethernet network transfer rates to and from field devices

– Communication with up to 64 field devices

– Downloadable I/O software drivers from available protocol libraries

– Up to 2000 DCI block connections

– Integration of field device data into the Foxboro DCS control database using an Ethernet connection

– Field Installation

– G3 rated (harsh) environments.

I/O Driver

The FBM is a general purpose Ethernet hardware module that can be loaded with different software drivers.

These drivers configure the FBM to recognise the specific protocol used by the device.

Some of these software drivers are standard products. Other custom drivers can be developed to meet specific needs.

These drivers are dynamically downloaded to the FBM233 with software code specifically designed to interface with the protocols of third party devices.

The configuration steps and software requirements for each driver are specific to the device integrated into the system.

Ethernet Link Setup

Data communication between the FBM233 and field devices takes place via the RJ-45 interface on the front of the FBM233 module.

The RJ-45 connector of the FBM233 can be connected to the field device via a hub or an Ethernet switch.

The FBM233 connects to an Ethernet switch or hub to communicate with one external device or up to 64 external devices.

Configurator

The FDSI Configurator sets up the FBM233 ports and XML-based device profiles.

The Port Configurator makes it easy to set communication parameters (e.g., Dynamic Host Configuration Protocol (DHCP), IP address) for each port.

The Device Configurator is not required for all devices, but when it is, it can configure device-specific and point-specific considerations

(e.g., scan rate, address to which data is to be transferred, and amount of data to be transferred in a single transaction).

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.

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.
