Interpreting the USB log
With the HomeVision® Pro version, a CSV (comma separated) log file is created on the USB
stick, the content of which can be read using Microsoft Excel for example.
Remember to specify in the menu system that the USB stick is to be removed, before physically
removing it from the control panel. If this is not done there is a risk of interrupting writing to
memory incorrectly and corrupting the file. Furthermore, you should create a copy of the log file and
save it somewhere else and then use this copy for analysis. Failure to do this can result in mistakenly
saving the file back on the USB stick in modified form, which can result in the control panel then
continuing to log. As soon as the copy is made, reinsert the USB stick so as not to lose any data.
When the copy is opened, allow Excel to sort the data into columns to resemble the example below.
The ”Unit ID” column indicates the Control unit's serial number. For entries created when no control
unit was connected, zero is given. ”PARAMETER NR” indicates the relevant param
eter's number, an
indication which has no value to the user unless it is used for sorting data or for searches.
”PARAMETER NAME” indicates the name of the relevant parameter and ”PARAMETER VALUE” the
relevant parameter's value at the time of the logging.
