The Graph View
Figure 4-5
- Sample Graph View
The Graph view shows logged data in a graphical for-
mat with sample times as the X (horizontal) coordinate
and sample values as the Y (vertical) coordinate. To access
a graph view:
1.
Highlight a value from any screen and press
to open the Actions Menu.
2.
Select Graph, and a graphed view of the selected
value opens.
Upon first entering the Graph view for a logged value,
all available samples are displayed. The X axis (sample
time) ranges from the time and date of the earliest avail-
able sample relative to the time and date of the latest sam-
ple. The Y axis (sample value) ranges from the minimum
sensor reading to the maximum sensor reading.
In the case of an input point log, (e.g., suction pres-
sure) assume the Log Group setup specifies Samples as
1000 and Log Interval as 0:03:00. Also assume that the
system has been running continuously with no interrup-
tions for one week. The X axis would span a time interval
starting approximately six days and six hours ago all the
way up to the present.
If suction pressure ranged from 18 psi to 25 psi during
the time period of the log, the Y axis of the graph would be
just large enough to show all samples in the log.

Zooming In and Out
For a more detailed view of a graph, zoom in by press-
ing . This results in half of the samples of the current
view being redrawn to fill the entire view. Using the above
example, the graph would now shows three days and three
hours of samples from the middle of the original graph.
Locating Logged Inputs/Outputs
Pressing again zooms in even farther.
Pressing zooms out, resulting in a graph whose
time scale spans twice that of the previous view. This dou-
bles the number of displayed samples.
Navigating a Zoomed View
While zoomed in on a graph, only a subset of the total
number of samples are visible. To view samples that were
recorded earlier or later than those in the current view,
press the left and right cursor keys. The availability of ear-
lier or later samples is indicated by the presence of arrows
at either end of the X (time) axis.

Checking Boards Online
Figure 4-6
- Network Summary Screen
You can check all boards that are on either the Echelon
Network (E2 controllers) or the I/O Network from the Net-
work Summary screen (See Figure 4-6). This screen dis-
plays information such as board status, name of the device,
type of device (board, controller, etc.), firmware revision,
the network address for each device, the number of Eche-
lon controllers (E2s) that are online or offline, and the
number of I/O boards online or offline. After determining
which board is offline, turn to Appendix A: Troubleshoot-
ing for more information.
To access the Network Summary screen:
1.
From the Main Menu screen, press
for the Status menu.
2.
Press
(Network Summary) and the Network
Summary screen will be displayed.
The Network Summary screen can also be accessed
by:
