5�1 Conguring sensors and actuators
When you connect a sensor or actuator to a WMPro, you
need to tell the device what you are connecting. A WMPro
measures V, mA, Ω or Hz, depending on the signal sup-
plied by the sensor. A scale factor or a conversion function
is applied to convert the reading into the quantity being
measured, e.g. °C, kPa, kWh or m
3
/h. The same applies to
actuators, only the other way around.
5�1�1 Databases
The WMPro has three databases, which are used to store
selected information at regular intervals. You can use
the sensor and actuator settings to specify the informa-
tion you want to store. The size of the database history
depends on how many values are saved at each interval.
If you only save values from a small number of sensors, this leaves space for a longer history. This is
why you have the option of selecting the values you are interested in.
The short time database normally stores information every second, so it contains momentary values.
The other two databases stored values every hour and once a day respectively. In these longer-term
databases, statistical information is usually more interesting than a snapshot of values at the begin-
ning of the hour/24-hour period. So you can choose from statistics like mean values, highest and
lowest values over the period, how much the signal varied over the period, etc.
5�1�2 Names and display options
The sensor settings include the name and other options
governing how the sensor/actuator will be displayed on
web pages and overviews.
Sensors and actuators
Sensors and actuators can also be
congured directly on the channel
page. For more details, see section
11.
This section explains how to change the settings for various types of sensor and actuator. The
settings relate to the sensor type and to the information you want to store in the databases. You
can also go to the channel page to change some of the settings directly.
Databases
Go to section 10 to nd out how
to use databases and view the
information they contain.
View menu
There is also a Sensors & Actuators
option in the View menu. The page
is the same as the Settings menu,
except you can view and update
current values. What you cannot
do is change any settings.
