9.4 Logging Variables
Logging of the variable values for future review or exporting can also be enabled by performing the following
steps:
Variable Properties Window – Log Tab
Step 1
Select the ‘Log tab’ of the Variable Properties window (right click the variable and select ‘Properties’if not
currently editing a new variable)
Step 2
In the Log Data field, select a time interval from the drop down box. The current variable value will be recorded
with a time stamp once every selected time interval.
Once each required temperature or humidity value from the appropriate registers has been stored in a variable,
the variables created can be used purely to log the data received. The logged values can be viewed in the
Protege System Management Suite by right clicking the variable name and selecting ‘Variable History’. This will
bring up the variable history which can be scrolled through, or exported to a CSV (Comma Separated Value) file
by right clicking any log value and selecting ‘Export’. This file is suitable for importing into Microsoft® Office
Excel or other processing software.
The variables can also be used to create graphical representations of the temperature and humidity levels for the
Protege Temperature and Humidity Sensor on a floor plan page in the Protege System Management Suite.
An
example of this is described in the following section.
