meet your functional, performance, and plant requirements. The switches allow you to interconnect system

components (controllers, workstations, servers) effectively and to minimize the quantities and lengths of

interconnectivity cabling.

OVERVIEW

The Modular Baseplates enable overall system

installation functionality by providing unit increments

of 2, 4, and 8 module positions in combination with

vertical and horizontal mounting.

These Modular Baseplates support distributed

control for both small and large systems and

specifically support the following I/A Series® system

DIN rail mounted modules:

 Field Control Processor 280 (FCP280) faulttolerant

or non-fault-tolerant

 Field Control Processor 270 (FCP270) faulttolerant

or non-fault-tolerant

 Field Communications Modules (FCM100Et and

FCM100E) and other FCMs

 Fieldbus Expansion Modules (FEM100E)

 Fieldbus Isolator/Filter Modules (FBI100)

 DIN rail mounted Fieldbus Modules (FBMs) and

100 Series FBMs connection.

 Splitters/terminators for time strobe and A/B

Fieldbus

 DIP switch for identification of certain Modular

Baseplates

 Backwards compatibility with existing DIN I/O

subsystems allowing for future expansion without

additional interface hardware

 Adding additional Modular Baseplates without

removing the system from service (requires

redundant bus)

 Keyed positions dedicated to FCP270 or

FCM/FBM only

 Passive backplane to increase system reliability.

MODULAR BASEPLATE MOUNTING

Most Modular Baseplates are available in two basic

mounting configurations — horizontal DIN rail mount

(see Figure 1) or vertical DIN rail mount (see Figure 2).

Either of these mounting configurations can be

employed internal to an enclosure, external to an

enclosure, or mounted on a secure DIN rail.

The DIN rail mounted Modular Baseplates provide the mounting platform and communication backplane for DIN rail mounted modules.

FEATURES

Key features of the Modular Baseplates are:

 2, 4, and 8 module positions in combination with

vertical and horizontal mounting

 Connection for optional GPS time strobe for

FCP280, FCP270, and FCM100Et

 Connection to the 2 Mbps Module Fieldbus for

the DIN rail mounted Fieldbus Modules, or to a

268 Kbps Fieldbus for the 100 Series FBMs

 Primary and secondary 24 V dc power and

communications connections

 Field connection for I/O termination assemblies,

redundant adapters and module identifiers for

each module

Fast Ethernet Switches

to The MESH Control Network Ethernet Equipment

(PSS 21H-7C3 B4).

4-Port 10 Mbps Hubs for ISO/DIN Rail

The 4-Port 10 Mbps Industrial Hubs are DIN rail

mounted and support 10 Mbps Ethernet protocol

to/from devices that communicate at speeds of

10 Mbps. You can connect up to three Ethernet

devices using one 4-Port hub. Multiple hubs can be

interconnected to connect up to 64 devices to a

single FBM232.The hub mounts on an ISO/DIN rail and the 24 V dc

can be supplied redundantly from the FPS400-24 to the hub.

A terminal block contains an integrated indicator

contact, receiving error and warning messages of the

hub which are defined as digital signals. These

signals, for example, can be utilized as process

messages when connected to a digital input FBM.

DIN Rail Mounted 5-Port 10/100 Base TX Switch

The 5-port 10/100 base TX Ethernet switch

(P0972WE) is Din rail mounted and available for use

with the FBM232. You can connect up to four

Ethernet devices using this 5-port switch.

Additionally, multiple switches can be interconnected

to connect up to 64 devices to a single FBM232.

For detailed physical and electrical specifications,

refer to Model SFNB 5TX 2891001 at

www.phoenixcontact.com/us/products.

Rack and Chassis Mounted Fast Ethernet

The indicator/contact becomes active as soon as

disturbances appear in the hub, that is, when a

power supply should fail or at least one twisted pair

port reports a faulty link status or has autopartitioned.

For diagnosis there are LEDs available which indicate

fault, link status, segmentation, power and received data.

Operations

The FBM232 can access up to 64 devices to read or write data. From the Foxboro

DCS control station to which the FBM232 is connected, up to 2000 Distributed Control

Interface (DCI) data connections can be made to read or write data. Supported data

types are determined by the particular driver loaded on the FBM232. which converts

the data to the DCI data types listed below:

• An analog input or output value (integer or IEEE single-precision floating point)

• A single digital input or output value

• Multiple (packed) digital input or output values (packed in groups of up to 32

digital points per connection).

Thus the FBM232 can access up to 2000 analog I/O values, or up to 64000 digital I/O

values, or a combination of digital and analog values up to the maximum capacity a

user allows within the sizing guidelines of the control processor. The frequency of

access to the FBM232 data by a control station can be as fast as 500 ms. The

performance depends on each device type and the layout of data in the device.

Configurator

The FDSI configurator sets up the FBM232 XML based port and device configuration

files. The port configurator allows for easy setup of the communication parameters for

each port (such as, Dynamic Host Configuration Protocol (DHCP), IP addresses). The

device configurator is not needed for all devices, but when needed it configures

device specific and point specific considerations (such as, scan rate, address of the

data to be transferred, and the amount of data to be transferred in one transaction).

I/O Drivers

This fieldbus module (FBM) is a generic Ethernet hardware module in which different

software drivers can be loaded. These drivers configure the FBM to recognize a

particular protocol used by the device. Several of the software drivers are standard

product offerings. Other custom drivers can be developed to meet specific needs.

These drivers are dynamically downloaded to the FBM232 with software code

specifically designed to interface with the third party device’s protocol. The

configuration procedures and the software requirements for each driver are unique to

the device(s) being integrated into the system.

Ethernet Link Setup

Data communication between the FBM232 and field devices are through the RJ-45

connector located on the front of the FBM232 module. The RJ-45 connector of the

FBM232 can be connected through hubs, or through Ethernet switches to the field

devices (refer to Ethernet Switches for Use with FBM232. page 12). Connection of

multiple devices to the FBM232 requires a hub or switch.
