Optional DeviceNet Communication

Powermonitor 3000 units with a catalog number ending in -DNT are equipped with a

DeviceNet port in addition to the native RS-485 port. The DeviceNet network is an

open-standard, multi-vendor, industrial device data network that uses a variety of physical

media. The DeviceNet network also provides 24V DC power to devices connected to the

network. The DeviceNet port and the native RS-485 port may be used simultaneously,

although overall data throughput may be reduced.

For detailed DeviceNet system installation information, including cable lengths, the

placement of terminating resistors, power supplies, and other media components, refer to the

DeviceNet Cable System Planning and Installation Manual,

publication DNET-UM072

Refer to the note at the beginning of Communication Wiring on page 36

Install suitable terminating resistors at the ends of the DeviceNet cable.

Configuration options for optional DeviceNet communication include the node address

(MAC ID) and data rate. Defaults are node 63 and 125 Kbps.

Refer to the Powermonitor 3000 Unit User Manual, publication 1404-UM001

TIP

Some DeviceNet devices are equipped with internal terminating resistors.

IMPORTANT

You must install and wire a suitable 24V DC power supply to the V+ and V- conductors in

the DeviceNet cable. The power monitor consumes less than 100 mA from the DeviceNet

24V DC supply.
