The NTFB01 Field Bus Termination Unit is a Harmony rack
I/O device that is part of the Symphony Enterprise Manage-
ment and Control System. It provides a communication link
between 15 frequency shift keyed (FSK) smart transmitters or
other smart devices and an IMFEC11 Analog Input Module
functioning in frequency shift keyed field bus mode.
Figure 1-1 shows the Harmony rack I/O architecture. A Har-
mony area controller and the Harmony rack controllers can
use the rack I/O module and termination units for I/O
interface.
