11.3.1.4 Special parameters and fields
$st $et
If Last time is specified: ($stL or $etL): there is a last time logged for each Tag plus a last time logged for all Tags.
If you specify a given Tag, its own last time will be used, if a specific Tag is not requested, the export is performed for all Tag
(concerned by historical logging) and another last time memory is used.
If output format is graph: $et_0 should be used instead of default value because otherwise the graph spans up to 31/12/2030.
For binary or text output, the default value can be kept.
$ft
Graph format is only allowed if 1 Tag has been specified.
Text format will output a comma-separated file.
The separator is ‘;’ to avoid confusion with decimal point.
If all Tags are output they will be output in a chronological order in the file.
$ut
If only one Tag is specified, the time of the last point for that Tag will be memorized.
All Tags can be output individually and last time is saved for each point.
Another memory if available if $ut is requested for ALL Tags.
$tn
If this Tag is not specified, ALL Tag will be selected for export.
Otherwise, the Tag with the given name will be selected.
