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.
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, several other
configurations are possible, including those using repeaters and
intrinsic safety protective devices. Repeaters allow a bus to be
expanded into multiple segments, 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.

The FBM223 has a compact design with a rugged extruded aluminum
exterior, providing physical and electrical protection for the
circuits. Enclosures specially designed for mounting the FBMs offer
various levels of environmental protection, up to harsh
environments per ISA Standard S71.04.
The module can be removed or replaced without disconnecting field
device termination cabling, power, or communications cabling.
