FOXBORO-FBM232 Field Device System Integrator Module

FOXBORO-FBM232 Field Device System Integrator Module

Key features of the FBM232 are: • 10 Mbps or 100 Mbps Ethernet network transmission rate to/from field device • Communicates with up to 64 field devices • I/O software driver is downloadable from a library of available protocols • Up to 2000 DCI block connections • Integrates field device data into a Foxboro DCS control database using Ethernet connectivity • Field mounted • Class G3 (harsh) environments. 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. 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). 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. The FBM232 collects the required data from the devices, performs the necessary conversions, and then stores the converted data in its database for incorporation into the Foxboro DCS plant management functions and operator displays. Data may also be written out to the individual devices from the Foxboro DCS system.
