Specify label to associate with instrument object
You configure Tag
to be a character vector
value that uniquely identifies an instrument object.
Tag
is particularly useful when constructing
programs that would otherwise need to define the instrument object
as a global variable, or pass the object as an argument between callback
routines.
You can return the instrument object with the instrfind
function by specifying the Tag
property
value.
Usage | Any instrument object |
Read only | Never |
Data type | Character vector |
The default value is an empty character vector.
Suppose you create a serial port object on a Windows® machine associated with the serial port COM1.
s = serial('COM1'); fopen(s);
You can assign s
a unique label using Tag
.
s.Tag = 'MySerialObj'
You can access s
in the MATLAB® workspace
or in a file using the instrfind
function and
the Tag
property value.
s1 = instrfind('Tag','MySerialObj');
