Text-File Historical Driver Information
Source Properties
Historical text sources are designed for situations where you have a spreadsheet or table of results with date-stamps.
When setting up the text file source, you'll be asked to specify…
| Option | Use |
|---|---|
| Path | The full path to the text file |
| Delimiter | The 'delimiter' character that separates the columns. If blank, it is assumed to be 'tab' |
| Label Column | The number of the column that contains the 'name' of the value |
| Date Column | The number of the column that contains the date as text or as a UNIX epoch |
| Value Column | The number of the column that contains the value |
| Timezone | The name of the timezone for the data. If blank, UTC is assumed. |
Note that in the above values, the column count begins at '1'. A zero indicates that the column is not present in your file.
Link Properties
These are the options that appear when you link a property to a text data source…
| Option | Use |
|---|---|
| Label | The lookup label |
2016-03-10 10:00 ROOM1_TEMP 12.5 2016-03-10 10:00 ROOM2_TEMP 16.95 2016-03-10 11:00 ROOM1_TEMP 11.4 2016-03-10 11:00 ROOM2_TEMP 18.23
In the above example, the property linked to the 'ROOM1_TEMP' label would get the value 11.4 when 11:00 on the 10th of March 2016 was requested.
