Field Device System Integrator Module

OVERVIEWA 

pair of FBM231 modules combine to provideredundancy at the Fieldbus Module 

(FBM) level, withfield wiring to two termination assemblies (seeFigure 1). In this 

configuration, one FBM231 is theMaster, and the other is the Tracker module. 

Inputpoints on the control station are updated from thedevice inputs received on 

the network connected tothe Master. Device output points, depending on theI/O 

driver, are written by both the Master and Trackermodule. Role switching is automatic 

if actualproblems are detected (for example, heartbeat) bythe I/O driver, or the 

user can switch the roles at anytime via SMDH.The FBM231 has four ports - each 

can beindividually configured in software for RS-232,RS-422 or RS-485. This allows 

a single FBM231the flexibility to connect to multiple similar but notidentical devices. 

Ports 1, 2, 3, and/or 4 can beconfigured as a single logical port with redundantcables 

allowing you to interface with dual-ported I/Odevices within your plant. The general 

networkconfigurations are shown in Figure 1.

The FBM231 and its associated terminationassemblies (TA) accommodate several 

types ofconnections to dual-ported devices; directconnection to devices; connection 

to modems whenused with the RS-232 communication interface, andmultidrop connections 

to RS-485 devices. Intrinsicsafety devices can be connected between the TAand the 

field device. For single ported devices, youshould use the FBM230.
