Sample Applications C-17
To read the date and time from the Powermonitor 3000, click the Read
graphic element. To write the data and time to the Powermonitor
3000, enter the desired data and time into the worksheet along with
the Powermonitor 3000 password (default = 0) and click the

Date and Time Summary
You may use the examples above as building blocks to create
applications to meet your business needs. Refer to Appendix A for
detailed information on the Powermonitor 3000 data tables as well as
the sections of this manual that describe the functionality you wish to
include in your application.
Rockwell Automation also offers software products such as
RSPower32 and RSEnergyMetrix that perform much of the data
integration work for you. Please contact your Rockwell Automation
representative for more information.
Multiple Data Table Reads
Using DeviceNet
The following is a ladder program designed to return a number
real-time data tables from a Powermonitor 3000 to an SLC 500
processor via DeviceNet using a DeviceNet scanner module. The
following example and ladder diagram uses these settings:
•
Node (MAC ID) = 5
•
Port = 0
•
Class = 4
•
Instance = 14, 16, 18, 20, 22, 17, 25
•
Attribute = 3
•
Command = 1, 4
•
Size 3
•
Size = 3
•
Service = 14
Explicit Message Transfer Setup
The Explicit Message Transfer Block header for this example is
assembled in integer file N10:0. The header contains the information
for all aspects of the transmission request. Each different node or
instance requires assembling another file. Each file has to be moved in
turn to the output M0 file starting at word 224.
