ETHERNET HUBS AND SWITCHES

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.

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 auto

partitioned.

For diagnosis there are LEDs available which indicate

fault, link status, segmentation, power and received

data.

Fast Ethernet Switches

For information on the Fast Ethernet switches, refer

to The MESH Control Network Ethernet Equipment

(PSS 21H-7C3 B4).

CONFIGURATOR

The FDSI configurator sets up the FBM232 XMLbased port and device configuration files.

The port configurator allows for easy setup of thecommunication parameters for each port

(such as, Dynamic Host Configuration Protocol (DHCP), IPaddresses).

The device configurator is not needed forall 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).

OPERATIONS

The FBM232 can access up to 64 devices to read or write data. From the I/A Series 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).

This FBM is a generic Ethernet hardware module inwhich 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 connectorlocated 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 HUBS AND

SWITCHES” on page 8). Connection of multiple devices to the FBM232 requires a hub or switch.

CONFIGURATOR

The FDSI configurator sets up the FBM232 XMLbased port and device configuration files.

The port configurator allows for easy setup of thecommunication parameters for each port

(such as, Dynamic Host Configuration Protocol (DHCP), IPaddresses).

The device configurator is not needed forall 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).

Remote Installation

The FCP280 simplifies Foxboro DCS system architecture by requiring only

the enclosure (via field enclosure) while maintaining control,

host workstation with Control Core Services v9.0 or higher, 

and an Ethernet switch to communicate through the control network structure.

The field-installed FCP280 is part of a highly distributed control network

In this network, the controllers work closely with specific process units

mounted in close proximity to their I/O and the actual controlled equipment.

The process units are coordinated via a fibre optic 100 Mbps Ethernet network.

The FCP280 and its network adapters are encased in a robust die-cast aluminium

enclosure that requires no ventilation due to its efficient design.

The FCP280 and its network adapter are CE certified and can be installed

without the need for an expensive dedicated cabinet, helping to protect against electronic radiation.

The FCP280. network adapters and backplane can be installed in G3 rated harsh environments.

This form of upgrade helps to prevent any significant impact on the local control process.

limits

– Liquid crystal display (LCD) shows letter errors as well as real-time roles and statuses

– Connects to the Foxboro DCS control network via standard fibre optic or copper 100 Mbps Ethernet

cable

Enhanced reliability (fault tolerance)

The FCP280’s unique, patented fault-tolerant operation improves 

reliability compared to traditional process controllers.

The fault-tolerant version of the FCP280 consists of two modules operating

 in parallel with two Ethernet connections to the control network.

The two FCP280 modules are combined as a fault-tolerant pair,

ensuring continuous operation of the controller in the event of any hardware failure in one of the

modules.

Both modules receive and process information simultaneously and faults are detected by the modules

themselves.

One important method of fault detection is to compare the communication messages of the modules’

external interfaces.

A message leaves the FCP280 only if the two FCP280s agree on the message to be sent (bit for bit match).

Once a fault is detected, both modules run self-diagnostics to determine which module is affected.

The modules run self-diagnostics to determine which module is affected. 

The unaffected module then takes over control without affecting the normal operation of the system.

This fault-tolerant solution offers the following key advantages over redundant-only controllers

LED Indicators

The light-emitting diodes (LEDs) on the front of the FCP280 module provide a visual indication of the

– FCP280 operating status

– Transmit/receive communication activity on the four extended fieldbus channels

(Fieldbus A and B on each channel) LEDs on copper or fibre optic

network adapters provide visual indication of the following

– Internal and external power supply health status

– Communication activity with the control network A and B links and the FCP280

Redundant controllers only:

– No error messages are sent to the field or to applications using the controller data,

because unless the two modules match exactly bit-for-bit in sending a message, the

No information is allowed to flow out of the controller.

– The secondary controller is synchronised with the primary controller,

which helps to ensure that the most up-to-date data is available in the event of a primary controller

failure.

– Since the secondary controller performs exactly the same operations as the primary controller,

potential defects can be detected prior to any switchover.
