2-2 Product Description
Master Module
Publication 1404-UM001D-EN-E - October 2004
The Master Module contains the main microprocessor-based
monitoring functions, including terminations for power system
connections, status inputs, control outputs, a native RS-485
communications port and a port for the Display Module.
Configuration
Although the Powermonitor 3000 ships from the factory with default
settings, you need to configure it for your particular requirements.
You may configure the Powermonitor 3000 using the optional Display
Module. Alternately, you may use an external device or application to
write configuration, operational parameters and commands to the
Master Module through its native or optional communications port.
Optional external applications that you may use for Powermonitor
3000 configuration include RSPower32
software operating on a computer with a Microsoft Windows
operating system. Contact your local Rockwell Automation sales office
or distributor, or visit http://www.software.rockwell.com/
information on available software packages.
