====Text-File Live Driver Information====

===Source Properties===

Live text sources are designed for situations where you have a system that regularly dumps information to a text file.

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|
|Value Column|The number of the column that contains the value|

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|

===Zero Labels===

**If you use zero as the label column number in your source**, the 'label' you use to connect your asset properties to live data will be the //order// of the values. Ie. to connect your temperature to the value in the third line of the file, the label would be '3'.

<code>
12.5
16.95
11.4
Stationary
</code>

A temperature linked to label **'3'** would receive a value of **11.4** from the file above.

===Non-Zero Labels===

If you've specified a label column number in your data source, the driver will search for a line with the label chosen in the link properties.

<code>
ROOM1_TEMP    12.5
ROOM2_TEMP    16.95
ROOM3_TEMP    11.4
ROOM2_FAN    Stationary
</code>

A temperature linked to the label 'ROOM2_TEMP' would receive a value of **16.95** from the file above.
