Label to associate with OPC Toolbox object
You configure Tag
to be a character vector value that uniquely
identifies an OPC Toolbox™ object.
Tag
is particularly useful when constructing programs that
would otherwise need to define the toolbox object as a global variable, or pass the
object as an argument between callback routines. You can return a toolbox object
with the opcfind
function by specifying the
Tag
property value.
