This value is
the maximum number on the gauge |
|
Lower Control
Limit (LCL) |
This is a
specified lowest allowable value. If
the node reading drops below this number, an alarm condition is created. |
|
Upper Control
Limit (UCL) |
This is a
specified highest allowable value. If
the node reading rises above this number, an alarm condition is created. |
|
SMS Alarm |
This field
must be checked for the SMS alarm to be activated for the node. If a limit is exceeded, and the SMS Alarm
box is checked for the node, an SMS Text message and/or email will be sent to
all SMS Alarm recipients. |
|
Alarm Control
Limit |
This is the
number of consecutive times the node data limit has is exceeded
before an SMS and/or Email notification
is sent. (Only works when SMS Alarm is checked) |
|
Precision |
Precision is
used to set the number of decimal places to display on the readings page. If no precision is used, decimal places
will be displayed depending on how large or small the reading value is at the
time. |
|
Node Detail |
If a binary value was used
in the “Unit” column, the type of binary is displayed in this column. Additionally, in applications requiring a
delta reading between two existing nodes a virtual delta node can be
configured. Values for the delta nodes are computed based on the delta logic
specified and are updated whenever the existing nodes change. In Figure 2, NodeID
13 is a delta node of NodeID 11 and NodeID 12. The Min and Max value for the Delta node will computed automatically based on previous nodes. |

SMS Alarm
Once
the box “SMS Alarm” is checked for one or more nodes on the Node Configuration
page, the user can configure which devices will receive those alarms using this
page (Figure 5).
Figure 5
These
alarms can be sent to any device capable of receiving an SMS message or email. This screen allows the user to specify any
and all devices that will be receiving the alarm notification. Based on these
settings, when an alarm condition occurs, an alarm SMS message is sent to the
listed cell numbers, and an email is sent to the listed email addresses.
Alarms
must be reset after they are triggered. This
mechanism is designed so that recipients do not receive constant alarm
messages. Clicking on the red “Alarm
Status” tab from any screen takes the user to the WGR Alarm History page. The alarm is reset from here by clicking on
the green “Alarm Reset” button.
To
add a recipient’s SMS capable device, enter the phone number (e.g. 15554443333)
and select “Add” button. Area codes and the “1” prefix are required on all
phone numbers. Click on “Edit” to
edit the name, number, or email of the recipient. Then click on “Update”
to save the values. To add an email only for a recipient, a “1” must be entered
into the “Phone#” field.
To
use SMTP server for sending email notification, click Edit on the “WGR cell
phone SMS Alarms configuration” table. Specify the SMTP Server name (e.g.
mailhost.mis.mycompany.com), SMTP port (e.g. 25). Only if Credential’s are
required to access the SMTP server then specify the UserID,
Password and Domain name. Then click on “Update” to save the data. (Figure 5a)

Graph
This
screen (Figure 6) is used to display WGR
nodes data in graphical format. Here users can view nodes data between “Start
Date” and “End Date”. The date format is
both date and time expressed as “m/dd/yyyy hh:mm:ss: AM or PM”. User specifies which Node ID(s) to be
displayed. User can select any node from the dropdown list or enter node id(s) in “Node ID for
Graph” field. E.g. 1 or 1,2,5,9 or 1-5,9,20 Check
“select All Nodes” to load all the node ids into the “Node ID for Graph”
field. To graph click “Show Graph”.
Graphing options include:
|
Auto Scale |
The graph will
automatically scale based on values.
By default, this is selected.
To turn off auto scale, uncheck the checkbox, and the “Min” and “Max
fields will enable |
|
Min |
If auto scale is turned
off, the user must specify the min Y value on the graph |
|
Max |
If the
auto scale is turned off, the user must specify the max Y value on the graph |
|
Y-Axis Zoom |
Allows the user to zoom
into data on both the x and y axis. By
default all zooming occurs only on the x axis |
|
Tooltip |
This allows the user to
see the actual reading value on the graph by hovering
the mouse pointer over a point on the graph. By default this option is
turned off to speed up graphing time |
|
Update |
If graphing options have
change, the user may click the “Update” button for the changes to take effect
on the graph |
|
Reset Zoom |
Resets the graph back to
the default view (no zoom) |
|
Log |
Check this for log scale
on y-Axis |
When
graphing multiple nodes, nodes will be from highest reading value to lowest
readings value in the legend. To improve
graphing performance, values may be removed for very large sets of data e.g.
several months worth of data. To ensure
all points are graphed, the user may need to adjust Start Date and End Date. To zoom into data on the graph, using the
mouse pointer, left click and drag the desired zooming area. By default, zooming occurs in the x direction
only. To zoom in on the y axis as well,
the user must select “Y-Axis Zoom”
Table
This screen (Figure 7) will
display node data in table format with the following parameters.
Timestamp: Timestamp of data reading
Node ID: The unique ID number of the WGR node
Description: The name of the
node
Units: The units of the gauge (e.g. PSI)
Above UCL: Indicates if an over-limit alarm occurred
Below LCL: Indicates if a below-limit alarm occurred
LCL: The lower control limit (LCL) value
UCL: The upper control limit (UCL) value
User can export data using
“ExportToExcel” option and save it in a local machine as .xls format.

Alarm Reset
When
a limit has been exceeded the amount of times specified in the “Excursion
Limit” field on the Node Config page, and SMS Alarm
has been enabled for that node, the alarm will trigger and send an SMS Text
alarm or email alarm to specified recipients.
Once this occurs, the specified SMS/Email recipients will no longer
receive alarm notices for these particular nodes. In order to start receiving alarm
notifications again, the user must reset the alarm via the Alarm Reset Page (Figure
9) by clicking on the “Alarm Reset” Button from the “Alarm Status” page. Click
on “Reset all” button to reset all the node alerts. To reset alarms for
individual nodes, find the node in the list, click “Edit” then uncheck the box
for the alarm that triggered, then click “Update” to save changes.
