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
.
Refer to the note at the beginning of Communication Wiring on
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
.
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.
