Powermonitor 3000 45
Optional DeviceNet Communications
Powermonitor 3000 units with a catalog number ending in -DNT are
equipped with a DeviceNet port in addition to the native RS-485 port.
DeviceNet is an open-standard, multi-vendor, industrial device data
network that uses a variety of physical media. DeviceNet 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 publication DN-6.7.2,
DeviceNet cable System Planning and Installation Manual.
Refer to the note at the beginning of Communication Wiring page 38.
Install suitable terminating resistors at the ends of the DeviceNet
cable.
Configuration options for optional DeviceNet Communications
include the node address (MAC ID) and data rate. Defaults are node
63 and 125k baud. Refer to the Powermonitor 3000 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 Powermonitor 3000 consumes less than
100 mA from the DeviceNet 24V dc supply.
