FOXBORO fbm230 231 232 233 The Field Device System Integrator (FDSI) Modbus Master driver

DESCRIPTION

The Field Device System Integrator (FDSI) Modbus Master driver is designed to smoothly integrate single or  dual-ported Modbus devices using several different Modbus protocols into an I/A Series® system.

FEATURES Key features of the FDSI Modbus Master driver are: 

· Integration of single and/or dual-ported Modbus  devices into an I/A Series system at the fieldbus  level 

· Exchange of real-time data between Modbus  devices and the I/A Series system 

· Compliance with the globally accepted and  widely used Modbus communication standard 

· Simplex (FBM230 or 232) or Redundant  (FBM231 or 233) operation of FDSI Fieldbus  Modules

· Support for three Modbus protocols: Modbus  RTU and Modbus ASCII protocols for serial  devices, and Modbus/TCP for Ethernet devices 

· Optionally available vendor-specific device  variations of Modbus drivers  

· FDSI hardware provides a barrier for network  security issues 

· Availability of standard I/A Series plant  management functions and operator displays to  Modbus devices 

· System Monitor detection of Modbus device  connectivity.

OVERVIEW 

The Field Device System Integrator (FDSI) Modbus  Master driver enables the integration of vendorindependent single or dual-ported Modbus devices  using one of several Modbus protocols into an  I/A Series system.

The Modbus Master driver allows the I/A Series  system to obtain real-time data from attached  Modbus devices, manipulate the data using state-ofthe-art control algorithms, and write output data to  the devices.

The Modbus Master driver is downloaded to the  appropriate single or redundant FBM, and allows the  FBM to translate the data sent to the I/A Series  system from the field device or vice-versa.

FBM230 

The FBM230 is equipped with four ports, each of  which can be configured to use either the RS-232,  RS-422, or RS-485 physical interface standard. The  FBM230 supports single-ported devices utilizing  either the Modbus RTU or Modbus ASCII  communication protocols, and provides a serial  interface between the I/A Series system and the  devices. Refer to PSS 21H-2Z30 B4.

FBM231 

The FBM231 is equipped with four ports, each of  which can be configured to use either the RS-232,  RS-422, or RS-485 physical interface standard. Two  FBM231s can be used to implement a redundant  serial interface between the I/A Series system and  dual-ported devices utilizing either the Modbus RTU  or Modbus ASCII communication protocols. Refer to  PSS 21H-2Z31 B4.

Easy Integration of Modbus Devices 

The Modbus Master driver allows you to include new  or existing Modbus-compliant devices in your  process, regardless of device manufacturer.  Incorporating an open communication standard like  Modbus in your system provides a wide range of  options when selecting the best field devices for your  process.

Flexibility 

The Modbus/TCP protocol uses Ethernet and TCP/IP  technologies. The simplicity and low cost of Ethernet  hardware combined with the high speeds and  reliability characterized by Ethernet networks greatly  improves plant efficiency and provides the flexibility  required to constantly keep up with changing  technology. Using an Ethernet network, you can  provide remote access to process data over the  network.
