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)
