CONFIGURATION
TRANSCEIVER
Digital Field Bus Communication Networks
To date, despite its many draw backs, the 4 - 20 mA ana-
log current loop has been the most widely accepted
standard for implementing process control systems. In
today’s manufacturing environment, however, automat-
ed systems are expected to help manage the process,
not merely monitor it. With the advent of digital field bus
communication networks such as CC-Link, DeviceNet,
PROFIBUS, and Smart Distributed Systems (SDS), gone
are the days of constrained information. Controllers can

now receive multiple readings from field devices (sen-
sors, actuators, etc.) in addition to diagnostic informa-
tion.
The physical model for each of these digital field bus
communica tion networks is very similar as shown in
Figure 15. Each includes one or more buses, an interface
unit, optical isolation, transceiver, and sensing and/or ac-
tuating devices.
