| Description | An object for controlling collection of data.
'idle' Indicates that no command is in progress.
'swapToNewFile' When written, the current VFile is frozen,
and a new VFile is created for collecting
data.
If the data collection mode is automatic
(see cdcVFileCollectMode), then the current
collection interval is stopped and a new
collection interval is started
(see cdcVFileCollectPeriod).
'collectNow' When written, base object values for
all associated data groups are fetched
and stored into the current VFile. This
value can only be written when the
collection mode is 'manual' (see
cdcVFileCollectMode). |
