OWMT-SOFT (M-4064) Overviewx1

Overview

Description

OWMT-SOFT is a data acquisition monitoring system for the personal computer.

It was designed and developed for use with the Microsoft® Windows® operating

systems. This makes OWMT-SOFT easy to install, setup and, operate. This puts all

the features you need within the familiar easy to use Windows® operating

environment including complete online help for all functions.

All data collected may be viewed graphically in real time or as a historical display.

OWMT-SOFT shows trends, minimum and maximum and indicates alarms. ASCII

data logging to a file is also available to allow import into other programs such as

spreadsheets and data base programs.

OWMT-SOFT can be used to collect data from a wireless network. Data from up to

six sensors can be displayed. Currently supported sensors include:

OMWT-TEMP15 Temperature

OMWT-TEMPRH Humidity

OMWT-AIN5V Analog 5 Volt'

OMWT-AIN10V Analog 10 Volt

OMWT-AIN20MA Analog 20 MA

OMWT-VIB Vibration

OMWT-MOT Motion

OWMT-SOFT is actually a DDE client application that works in concert with a DDE

server application called OWMT-SOFT-DDE. OWMT-SOFT-DDE handles the

details of communicating or receiving data from the wireless sensors. OWMT-

SOFT-DDE verifies that the communication is correct, processes the sensor samples

and then forwards the data to the DDE client. OWMT-SOFT is responsible for the

presentation and analysis of the collected data.

2xOverview OWMT-SOFT (M-4064)

Quick Start

When OWMT-SOFT runs for the first time this help screen is displayed

You may access this screen again by clicking

Help

on OWMT-SOFT menu bar then

select

Contents

then

Quick Start

. A shortcut icon will be created in the installation

program group that points to the "OWMT-SOFT.HLP" file.

Make sure your receiver is plugged into your serial port and that no other application
is using that port before you start OWMT-SOFT. OWMT-SOFT will try to find the
receiver. If it cannot find the receiver, you may specify which receiver and COM
port you are using.

OWMT-SOFT begins in

Numeric mode

. All

alarms

are disabled, data logging is
disabled, and historical data accumulation is set Start/Stop. To enable or change any
of these features you will need to click the Setup menu and select the OWMT-SOFT
Setup or Device Setup menus.

To use the

Historical View

option you must let OWMT-SOFT run for a while to

accumulate some data to be displayed. While in

Historical View

mode you can

Zoom and

Analyze

the data. An example session is provided.

Wireless Setup

OWMT-SOFT automates the process of setting up your hardware. You have to
select the sensors you want to use. Follow these steps to start.

1. Connect your receiver (OWMT-RS232-600) into your serial port.
Verify that no other software is using this serial port.

2. Start OWMT-SOFT. OWMT-SOFT will display the Quick Start help
the first time.

3. Once the Quick Start Help is exited, OWMT-SOFT will try to find a
receiver. If it cannot find a receiver, OWMT-SOFT will prompt for a
receiver type and port number. When OWMT-SOFT finds a receiver,
it will display the “Add Wireless Device” window.

4. You will need to define what sensors, OWMT-SOFT will use. When
OWMT-SOFT receives packets from wireless sensors, it will name
them and display their name and serial numbers in the “New Device”
listbox. You can speed up OWMT-SOFT-DDE's collection of sensors
by un-checking "Service Mode Only" (which is checked by default). If
"Service Mode Only" is checked, then OWMT-SOFT-DDE will only
display sensors received by pressing the service button on the wireless
sensor. This allows you greater control in selecting wireless sensors.

5. When the correct sensors are displayed, click on a sensor to highlight it
and click on the "Edit" button. A setup screen will appear. Select the
transmission rate for the sensor. The default is 60 seconds. OWMT­SOFT will use this transmission rate to determine if a device is offline.
By default, a device is considered offline if OWMT-SOFT has not
received a packet from the device in (3 * the transmission rate)
seconds. This interval can be changed.

OWMT-SOFT (M-4064) Overviewx3

6. When you have the sensors you want, click "OK" to start viewing their

data.

7. OWMT-SOFT will now display the data received by the receiver.

4xSetup OWMT-SOFT (M-4064)

OWMT-SOFT Setup

Do Not Prompt For Temperature From Probe

If this box is checked then OWMT-SOFT will not prompt you to create a
temperature object from the temperature sensor contained inside some probes such as
humidity.

OWMT-SOFT (M-4064) Setupx5

Trend Sensitivity

This field requires a number of seconds between 1 and 255, which sets the length of
time for the running average used to calculate the trend sensitivity. The larger the
number the slower the trend will respond to changes.

The default value is 20 seconds.

Units

The units field selects which scale OWMT-SOFT will use to display readings for
devices that have more than one scale.

There are three temperature scales

Fahrenheit, Celsius

and,

Kelvin

.

There are seven pressure scales

in of Hg, kiloPascal, milliBar, cm of H2O, mm of

Hg, kg / cm2

and,

atmos

.

Analog devices can be set up for any units, but the default is %. Set up the units for
analog in the "Device Setup" screen.

Changing any unit field will cause current graph(s) and display(s) using the changed
unit to be recalculated and updated based on the new units setting.

The default value for temperature is

Fahrenheit

.

The default value for pressure is

in of Hg

.

Note: If the units are changed while OWMT-SOFT is logging ASCII data a new
header record will be inserted into the file. However you may want to stop OWMT­SOFT first and rename your log file to prevent having two types of data in the same
file. This can make the data confusing and difficult to analyze.

Graphing

Display Grid

If this box is checked then vertical and horizontal grid lines will be displayed on both
Real Time and Historical Graphs.

6xSetup OWMT-SOFT (M-4064)

Alarm Lines

If this box is checked then horizontal lines will be displayed on the Real Time graph
to show where the current high/low alarm set points are.

Alarming

Alarm Notification Window

If this box is checked then OWMT-SOFT will pop a notification window up on top
of the current application when any alarm condition occurs.

This window will also display the nature of the alarm and start the Alarm Sound.

Clicking the OKbutton on the alarm notification window will close it and stop the
alarm sound if it is set to Sound Continuously.

Default setting is on. (Checked.)

Sound Continuously

If this box is checked then the currently selected sound will be repeated until the user
acknowledges the alarm condition by clicking the OKbutton on the alarm
notification window.

The default setting for this is enabled. (Checked.)

Logging

Log File Enable

If this box is checked then the log file

“OWMT-SOFT.LOG”

will be updated with
readings based on the current Log File Rate. Each log files first record will be a
header formatted as follows:

"DeviceA Serial Number,DeviceA Type,DeviceA Name,Current Units","DeviceB
Serial Number,DeviceB Type,DeviceB Name,Current Units" and so on for each
device.

Scale will be the current unit setting for the device.

OWMT-SOFT (M-4064) Setupx7

Values logged will be in the current scale unit. Changing units with logging enabled
will result in two or more different types of readings in the same file.

If devices are changed by adding, removing, or replacing, a new header record will
be generated inside the file to separate the data.

If

“OWMT-SOFT.LOG”

does not exist then OWMT-SOFT will create this file in

the same directory where OWMT-SOFT resides, typically C:\OWMT-SOFT.

The following format is used to log data readings:

Time,Date,DataA,DataB

Example: 13:44:30,3/22/96,54.70,70.34

Log File Rate

This field requires a number between 1 and 32,767, which will represent the number
of seconds between readings being written to log file. The value of this field will
have no effect unless Log File Enable has been checked.

The default value is 60.

Caution:

Setting this value to a low number and allowing OWMT-SOFT to run for

long periods of time will result in a very large log file.

Historical

Historic Session

A new session is created each time OWMT-SOFT is started or when the

Historic

Period

has expired. The length of a Historic Session is selectable by the user in

setup.

If historic data is enabled and the user changes session length i.e. from 4 hours to 8
hours, OWMT-SOFT will terminate the current session and start a new session based
on the new session length.

Historic Period

This field displays a selection box for the user to choose how long a session will be.
Choices are NONE, Start/Stop, 4, 8, 12 hours and 1, 2, 3, 5, 7 days. When NONE is
selected no historical data is saved. The

Historic Rate

is changed automatically
when Historic Period is changed. It will be from 1-42 seconds depending on the
length of period selected. When Start/Stop is selected a button will appear on the

8xSetup OWMT-SOFT (M-4064)

toolbar to allow you to start and then stop a historical session. While in Start/Stop
mode data is logged at once per second with a 10 second minimum.

The default value is Start/Stop.

Historic Rate

This field is display only, and displays the current rate of logging based on the
session period selected. Rate is defined as number of updates per second and ranges
from 1-42. The longer the

Historic Period

the more delay between updates. At 4

hours, 1 update per second will occur. At 7 days, 1 update per 42 seconds will occur.

Device Setup

Select Device

All devices that are or have been active are displayed in the select device to edit
window. The current online device(s) will have an * in front of their name.

Add Difference Monitor Button

When selected, OWMT-SOFT adds a Difference Monitor device to the Select
Device list. You then can setup the Difference Monitor as you would any other
device, specifying a name, alarm points, etc. A Difference Monitor allows you to
view the difference between two like devices, for instance, two temperature sensors
or two analog sensors. When configuring a Difference Monitor for analog sensors,
the analog sensors must have matching units, scale, and offset. If there are too many
sensors on the Real-Time View, the Difference Monitor may not be displayed.

Label Tab

Serial Number

Displays currently selected device's serial number. Cannot be edited or changed.

Name

A 10 character alphanumeric field to allow the user to enter a unique name or ID for
each device.

Alarming Tab

Alarm Levels

Checking the enable box will enable high/low alarming for selected device. High and
low alarm points should then be entered for that device.

Default setting for device is disabled. (Not checked)

Alarm Rate of Change

Checking the enable box will enable rate of change alarming for selected device. A
value in current units per minute should then be entered for that device. And check
“+” or “-” slope to determine whether the alarm will occur when the rate of change is
increasing “+” or decreasing “-”. Both “+” and “-” slopes may be selected at once.

In order for the alarm to trigger again the slope has to be zero or change direction.

10xSetup OWMT-SOFT (M-4064)

Default setting for device is disabled. (Not checked)

Alarm Sounds Tab

If Alarm Notification is enabled for a device then sounds will be enabled for that
device.

These sounds are played when the alarm notification window is displayed.

Default Sounds

If this box is checked then currently available Windows® sounds will be used for
alarm notifications. Otherwise “WAV” file sound will be enabled. OWMT-SOFT
has default “WAV” files for all alarms. These may be changed through setup.

The default setting for this is disabled. (Not Checked.)

WAV File Selection

If Alarm Notification is enabled for a device then sounds will be enabled for that
device.

These sounds are played when the alarm notification window is displayed.

If default sounds are selected then “WAV” files cannot be played.

To have OWMT-SOFT play a “WAV” file for the alarm condition indicated, you
can either type the name of the “WAV” file in the setup dialog box including the full
path (if no path is entered OWMT-SOFT expects the file to be located in the
OWMT-SOFT directory or in the Windows® directory), or click the browse button
and use the Windows® file selection window to find and select the desired “WAV”
file. You may use the same file for all alarms or you may have a different file for
each alarm. Clicking the play button allows you to preview the sound.

Alarm Images Tab

Bitmap (BMP) File Selection

You may select the images OWMT-SOFT displays for the alarm conditions. You can
click the image you want to change or click the browse button and use the file
selection window to find and select the desired “BMP” file.

OWMT-SOFT (M-4064) Setupx11

OWMT-SOFT has a set of four images that are used as the default images for
alarms.

The bitmap image is displayed as a 100 X 100 pixel image. If you select an image
that is larger than this, it will be scaled to fit and may not appear as expected.

Trend Images Tab

Bitmap (BMP) File Selection

You may select the images OWMT-SOFT displays for trends. You can click the
image you want to change or click the browse button and use the file selection
window to find and select the desired “BMP” file.

OWMT-SOFT has a set of up, down, and sideways arrows that are used as the
default images.

The bitmap image is displayed as a 100 X 100 pixel image. If you select an image
that is larger than this, it will be scaled to fit and may not appear as expected.

Scale Tab

Analog devices only

. This tab allows you to specify the scale and offset to be
applied to the analog data. Analog data is usually displayed in percent (%) 0-100. If
you wish to scale the data you may enter the information here. The scale and offset
will be applied before the data is displayed. The formula is

displayed data = (Scale * raw data) + Offset.

Also on this screen, you may select the decimal places (precision) shown when the
data is displayed. The scale screen also has a place to enter units, in both a long
string (displayed on the graph) and a short string (displayed in numeric view.)

Scale and Offset Calculator

This calculator will calculate scale and offset for you when you enter two points.
Each point has a raw value and a scaled value. Enter these in the boxes and the scale
and offset will be calculated.

Remove Device

When you select this option a list of devices is shown. The list only includes devices
that are not currently being displayed. Devices no longer being polled or Difference
devices that don't fit on the screen may be shown here. You may double click to
remove these devices from the device list.

Numeric

In this mode the following information will be displayed for each channel:

Current data in current scale units reading.

Minimum reading since last reset.

Maximum reading since last reset.

Current trend: up, down, or constant.

Alarm state: High, Low, or, None.

Current scale: units.

Labels for each device.

To reset minimum or maximum readings double clicking on

min, max

or the

on the display will show the

date and time the condition occurred.

A large red “X” will appear over the data reading if OWMT-SOFT loses
communication with the device.

Real Time

Real Time mode displays a graph that is updated real time based on a one second
update rate. The window then scrolls to the left with time as new points are added. A
numeric display also shows the current temperature reading and sensor label. If

Display Grid

is enabled then an XY dotted grid will be displayed on the plot

background. If

Alarming

is enabled and alarm points are within current

Units Scale

range, then alarm lines will also appear on plot background. Note only the alarm

changes occur dynamically with real time data updates to the graph. Right clicking
with the mouse over a point on the graph trace will cause the date, time, and value of
that point to be displayed at the right side of the toolbar. This allows you to
accurately determine the time and value of a specific point on the graph. If you
double right click and hold the right button down on the second click the toolbar
readings will zero for time and value; if you then continue to hold the button down
and move the mouse along the graph the offset will be displayed from where you
started. You can then determine elapsed time and the difference in value between
two points on the graph.

Units Scale

Clicking on the S button on the real time graph may set the units scale range. You
may enter value(s) for maximum and minimum Y-axis scaling. Optionally, clicking
the

Calculate Axis Minimum/Maximum

button will cause OWMT-SOFT to
calculate values automatically based on the data collected to that point. To change
the time scale press the

Time

button on the toolbar.

Historical

Historical mode displays a graph that is created based on the data loaded from the

Select Session

window. After session is loaded, all points are displayed to view more

detail. You can switch to historical zoom view with the

Zoom Function

and then

Zoom

in and stretch time. Analyze and Data Pan features are then made available

while in historical zoom mode. If

Display Grid

is enabled then an XY dotted grid
will be displayed on the plot background. Right clicking with the mouse over a point
on the graph trace will cause the date, time, and value of that point to be displayed at
the right side of the toolbar. This allows you to accurately determine the time and
value of a specific point on the graph. If you double right click and hold the right
button down on the second click the toolbar readings will zero for time and value; if
you then continue to hold the button down and move the mouse along the graph the
offset will be displayed from where you started. You can then determine elapsed
time and the difference in value between two points on the graph.

Zoom Function

You can expand the historical graph time axis by placing the mouse on the graph,
then press and hold the left mouse button and drag the mouse to draw a box around
the area of the graph to be zoomed. The view will switch to historical view mode.
The graph will be expanded to full window size and re-scaled to show the expanded
time range. A scroll bar will appear below the graph for panning and an

Undo Zoom

button will appear. Now dragging the scroll bar will allow you to pan through the
data with more resolution. This process of zooming may be repeated until the data
can be viewed in suitable detail or for a total of 10 zooms. Clicking the

Undo Zoom

button will step back through each zoom until all points are again displayed. Only
one historical data session may be zoomed and analyzed at one time.
