PXG Real Time Clock
The PXG600E maintains an internal real time clock. This clock can be set
manually through the Web UI or automatically synchronized to a system
clock using NTP.
This clock is used to time stamp data and events from “downstream”
devices. The resulting time stamped events and data can be viewed in the
PXG600E web pages or automatically reported to the Power Xpert Software
for integration into an enterprise power management system.
To support high accuracy of event time stamps, the PXG600E also integrates
the capability to synchronize the clocks in certain INCOM devices to the real
time clock in the PXG600E. The list of devices that support this feature can
be found on the PXG600E device data map. Please refer to the device data
map at

.
Trend Viewing
The PXG600E allows the user to view real-time trend graphs for individual
parameters for supported devices. The user can select to enable trending on
the Device Configuration page. Once trending is enabled, an icon will be
displayed next to the trended parameters on the Device page. Clicking on the
icon will take you to the trend graph for that particular parameter. There is
an option to view the past 24 hours, 7 days, 30 days or All Data when you
access the Trend Graph page. It should be noted that if this option is not
selected for a given device, the data will not be available to graph and it will
not be published to Power Xpert Software and it will not be populated in the
data log. The list of devices that support this feature can be found on the
PXG600E device data map. Please refer to the device data map at
www.eaton.com/pxg
.
Data, Interval and Event Logs
The PXG600E stores both historical data and events that can be downloaded
into a human readable file, CSV format. This file can be used to perform
analysis to discover potential system issues or perform maintenance on a
proactive basis.
Waveforms
The PXG600E supports waveform acquisition for selected devices capable of
generating waveforms. This feature is user-selectable on the device
configuration page. The waveform files are converted and stored as a
COMTRADE file format. The files can then be downloaded and viewed using
a standard COMTRADE waveform viewer. The list of devices that support
this feature can be found on the PXG600E device data map. Please refer to
the device data map at
www.eaton.com/pxg
.
NOTICE: The Modbus communication versions of the Feeder
Protector and Motor Protector relays (i.e. FP5000 and FP6000) are
not capable of generating waveforms.
