Optional DeviceNet Communications

Powermonitor 3000 units with a catalog number ending in “-DNT” are
equipped with an optional DeviceNet communication port in addition
to the native port. Both may operate at the same time. You must
configure the DeviceNet communications parameters before you
connect the Powermonitor 3000 to a DeviceNet network. Use the
Display Module under the Program > Optional Communications
menu. The DeviceNet configuration parameters include node address
(or MAC ID), baud rate, and bus-off interrupt response.

Node address: Range 0 to 64, default 63.
Baud Rate: Range 125, 250 or 500 Kbaud fixed rate, AutoBaud

or Program Baud. Default 125 Kbaud fixed rate

Bus-off Interrupt: Specifies the response to a CAN bus-off

interrupt.

Remotely settable node addressing (node address = 64) enables
RSNetworx™ for DeviceNet to configure the node address of the
Powermonitor 3000. In addition, this allows client devices that support
the DeviceNet Offline Connection Set to identify nodes with duplicate
addresses and automatically reassign the addresses of the offending
nodes.

AutoBaud allows the Powermonitor 3000 to automatically adjust to
the prevailing baud rate of the DeviceNet network. Program Baud
