through a single cable from a program-
mable controller directly to smart
devices such as sensors, push buttons,
motor starters, simple operator inter-
faces, drives and weigh modules. You no
longer have to hard-wire each device to
an I/O module or I/O block. Because
you use significantly less wire, you
spend far less time and money on wiring
and installation time. The network also
provides access to the intelligence
present in the devices for superior diag-
nostics and troubleshooting to help
increase system up time. The DeviceNet
network lets you monitor your plant-
floor devices from a central location and
reconfigure them as your needs change
or service them as required. You can, for
example, configure the weigh module for
different applications. The DeviceNet
network's capabilities help ease integra-
tion, and reduce installation and wiring
costs. (See Fig. 1-1)
