FBM230 FOXBORO
OVERVIEW
The FBM230 has four ports – each can be
individually configured in software for RS-232,
RS-422 or RS-485. This provides a single FBM230
the flexibility to connect to multiple similar but not
identical devices.
The FBM230 and its associated termination
assembly (TA) accommodate several types of
connections to single ported devices; directconnection to devices; connection to modems when
used with the RS-232 communication interface, and
multidrop connections to RS-485 devices. Intrinsic
safety devices can be connected between the TA
and the field device. The general network
configurations are shown in Figure 1.
FIELDBUS COMMUNICATION
The Fieldbus Communication Module (FCM100Et or
FCM100E) or the Field Control Processor (FCP270)
interface the redundant 2 Mbps module Fieldbus
used by the FBMs. The FBM230 accepts
communication from either path of the redundant 2
Mbps Module Fieldbus – should one path fail or be
switched at the system level, the module continues
communication over the active path.
