Specify whether data and event information are saved to one record file or to multiple record files
Description
You can configure RecordMode
to be overwrite
, append
, or index
. If RecordMode
is overwrite
, then the record file is overwritten each time recording is initiated. If RecordMode
is append
, then data is appended to the record file each time recording is initiated. If RecordMode
is index
, a different record file is created each time recording is initiated, each with an indexed filename.
You can configure RecordMode
only when the object is not recording. You terminate recording with the record
function. A object that is not recording has a RecordStatus
property value of off
.
You specify the record filename with the RecordName
property. The indexed filename follows a prescribed set of rules. Refer to Specifying a Filename for a description of these rules.

Example
Suppose you create the serial port object s
associated with the serial port COM1.
Specify the record filename with the RecordName
property, configure RecordMode
to index
, and initiate recording.
The record filename is automatically updated with an indexed filename after recording is turned off.
Disconnect s
from the peripheral device, remove s
from memory, and remove s
from the MATLAB workspace.
