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.

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
