FOXBORO FBM222

Description

The FBM222 Redundant PROFIBUS Communication Interface Module provides a reliable, high-capacity
interface between PROFIBUS-DP slave devices and the I/A Series
®
system.
FEATURES
Key features of the FBM222 are:
Integrates PROFIBUS-DP/PA slave devices into
the I/A Series control system
Conforms to the PROFIBUS-DP Specification
IEC61158 Part 3
Supports up to 125 slave devices per port with
full 244 byte data transfer
Maximizes uptime by providing redundant TAs,
hot-swappable redundant FBM modules, and
fully redundant communication between the
FBM222 and fault-tolerant control processors
Enables addition, modification and removal of
devices without impacting on-going operations
Propagates the PROFIBUS-PA device values and
status to I/A Series control blocks
Provides a user-selectable status parameter for
input data as well as read-back values for output
data
Supports PROFIBUS-DP Class 1 and Class 2
Masters along with multi-master configurations
Provides two galvanically isolated PROFIBUS
channels
Suitable for installation in Class 1, Division 2 and
Zone 2 locations
Supports the FBM223 Termination Assembly
allowing a simple upgrade from an FBM223 while
maintaining existing wiring and cable.
OVERVIEW
The Redundant PROFIBUS Communication Interface
Module (FBM222) provides an interface between the
I/A Series system and PROFIBUS-DP/PA slave
devices, including motor drives, I/O modules, and
field I/O devices. The FBM222, which can be used in
a single or redundant configuration, supports two
PROFIBUS links with a maximum of 125 slave
devices per port when repeaters are utilized. The
FBM222 connects the slave devices to the versatile
and robust I/A Series control system via Distributed
Control Interface (DCI) blocks. Physical PROFIBUS-
DP wiring is in accordance with Electronic Industrial
Association (EIA) standard RS-485.
There are multiple ways to connect FBM222s
installed as a redundant pair to a PROFIBUS-DP
network. When the PROFIBUS segments are single
networks as shown in Figure 1, an FBM228/FBM222
Redundant Adapter (P0922RK) connects a single
termination cable to the redundant pair. The other
end of the cable is plugged into a termination
assembly (TA), which provides connections for the
two network segments (Figure 1).
