Communications 4-15
Optional ControlNet Communications
Powermonitor 3000 units with a catalog number ending in “-CNT” are
equipped with an optional redundant ControlNet port and a native
RS-485 port in a dual-port configuration that allows simultaneous
operation of the ports. You must configure the communications
parameters before you connect the Powermonitor 3000 to a
ControlNet network. Use the Display Module under the PROGRAM >
OPTIONAL COMMUNICATIONS menu.
The only configuration parameter is the ControlNet node number
(also called MAC ID). The range of this parameter is 1 to 99 with a
default of 99. A node number of 0 is typically used as the address of a
ControlNet scanner.
Data Messaging Overview
Through communications, the Powermonitor 3000 becomes an
effective source of power and energy data to enterprise information
and automation systems. This section of the manual provides an
overview of data messaging with the Powermonitor 3000. Following
the overview, discussions will focus on the details of messaging using
specific communications types (e.g. serial, Remote I/O, DeviceNet and
Ethernet).
