Glossary
Address Code
Each X10 device has a user settable address used to
identify it from others on the same power circuit.
Alarm
An Alarm means notifications sent by Whzan to the Customer
based on Customer set threshold values of datapoints.
You may
want to keep your home at a certain temperature, for instance.
You can ask Whzan to alarm you when the home temperature drops
below the level you want it to be. Alarms can be set on
any datapoint
or derivatives of datapoints
and alerts by
email.
COM Port
A COM port is a communications channel over which data is
transferred between computing devices.
Controller
In the Whzan context, a Controller is the part of a device
that controls it, or it can be a separate device that controls
another, such as a control panel for a boiler.
Data Center
In the Whzan context, this is the Center where the
different types of data are defined. Different types of data
can include alpha and numeric characters, for instance.
Datapoint
Datapoints in Whzan hold values, that is numbers, dates,
text and Booleans (logical on/off). Once defined, Whzan
datapoints
can be displayed, stored in history, used in
calculations, subject to alarm checking and set via screen
graphics. Their values can be set from or sent to Whzan
Gateways such that they keep in synchronization with the
external world.
Device
A Device in the Whzan context is many things. In the field
of Home Automation, a device can be the house boiler, the
garden lights (or the control panel that controls your garden
lights) or the heating of a swimming pool. In an industrial
context, a device can be an instrument, a control panel or
tool, a piece of software controlling the air-conditioning of
an office or a PLC
which is used to control an element of a
production line or system. We also use the words 'equipment' and
'instrument' often instead of Device.
Dynamic change
In the case of Whzan, when a datapoint
value changes, any
displayed graphics containing a reference to that datapoint
may also be set to change. Most properties (e.g. color,
thickness, style, height etc) of each graphical component
(line, rectangle, image, Widget etc) can be bound to a
datapoint
or a derivitive of it. So as well as Widgets
showing changes any part of a
mimic
may change. This could be a Widget showing the temperature of your
swimming pool water as a gauge, and the color of the pool
water.
Gateway
A Gateway in Whzan is a software program that can be
downloaded from the Whzan Shop. Its function is to exchange
data between Whzan and the outside world. A Gateway can be
created to operate on any computer platform as long as it has
an internet link.
Gateway Manager
This is software which is embedded in the Gateway software.
Its role is to manage the Gateway and helps you to setup Whzan
and the Gateway itself.
Graphics Editor
The Graphics Editor is the Whzan graphics drawing programme
which allows the Whzan user to edit and create graphics for
displays and user intervention.
Graphics Object
In software that is used to draw pictures, each picture or
element thereof is regarded as an "object". In case of Whzan,
a graphics object could be a part of a picture that you are
drawing of your home automation system (the lights in the
house and garden maybe) or of the industrial production
process, like a biscuit baking production line.
History
Whzan enables you to store changes to datapoints
over time.
Once stored, the data can be extracted and shown on charts and
graphs.
Internet cloud
An internet cloud is a facility to provide the user almost
limitless computer capacity both in terms of processing power
and disk space. The facility is provided by a number of
service providers.
Mimic or Graphics
This is a graphical display created with the Whzan Graphics Editor
which is typically a drawing of the device (home boiler,
garden lights etc), instrument or production which you can
monitor using the Whzan service across the Internet. The
drawing effectively "mimics" or copies the behaviour and look
of the device environment.
Open architecture
The Open architecture of software, including the software
underpinning the Whzan service, means that the structure of
the software is such that it is easy to add new pieces of
additional software code to the original software code.
Serial port
A Communications interface on PCs usually with a 9 or 25
pin connector.
SDK
Software Development Kit.
Template
In the Whzan context, we are providing Whzan users
different ready-made combinations of Widgets
and
Mimics.
We call these Templates.
USB
Universal Serial Bus. A communications interface on
modern PCs.
Widget
A Widget in Whzan is a pictorial element that can
dynamically change in relation to a datapoint.
Widgets
are typically parts of an overall Mimic. It could be a
pictorial representation of a dial of a clock, thermometer or
speed gauge. In Whzan, there is a selection of ready-to-use
Widgets
that you can insert into your Mimic picture of your
system that you want to monitor across the Internet using
Whzan.
X10
X10 is a communications protocol that devices can use to
talk to each other.
X10 Controller Device
This plugs into your power supply and PC. The PC then
can send commands to control other X10 devices on the power
circuit.
