Foxboro FBM223 PROFIBUS-DP™ Communication Interface Module
FBM223 PROFIBUS-DP™ Communication Interface Module
The FBM223 PROFIBUS-DP™ Communication Interface Module provides an interface between
PROFIBUS-DP slave devices and the I/A Series® system.
FEATURES
Key features of the FBM223 module are:
Conforms to PROFIBUS-DP Fieldbus
specifications
Provides full support for all device variables and
diagnostic messages
Integrates PROFIBUS slave device data into an
I/A Series control database
The FBM223 and its associated termination
assembly (TA) are suitable for installation in
Class 1. Division 2 and Zone 2 locations.
OVERVIEW
The PROFIBUS-DP Communication Interface Module
(FBM223) provides an interface between
PROFIBUS-DP slave devices — such as motor
drives, I/O modules, and field I/O devices — and the
I/A Series system.
FBM223
PROFIBUS is a vendor-independent, open fieldbus
standard for a wide range of applications in process
automation and manufacturing. Vendor
independence and openness are guaranteed by the
PROFIBUS Fieldbus standard EN 50170. which
specifies the functional, electrical, and mechanical
characteristics for a serial transmission bus.
Physical PROFIBUS-DP wiring is in accordance with
Electronic Industrial Association (EIA) standard RS
485.
In addition to the general PROFIBUS-DP
configuration shown in Figure 1. several other
configurations are possible, including those using
repeaters and intrinsic safety protective devices.
Figure 2 shows how a bus can be expanded into
multiple segments through the use of repeaters, thus
providing support for a greater number of slave
devices.
FBM223 communicates with the PROFIBUS I/O
devices on a master/slave basis. As master, the
FBM223 initializes each data communication
exchange. The slave devices can only acknowledge
received messages, or send messages to the master
when requested to do so.
PROFIBUS-DP TECHNOLOGY
“DP” (in PROFIBUS-DP) represents the
communication profile that is most often used with
PROFIBUS — decentralized periphery. It is optimized
for speed, efficiency, and low connection cost, and is
designed especially for communication between
automation systems (such as the I/A Series control
system) and distributed field devices.
