opcfind - Find OPC Toolbox objects with specific properties
Syntax
Out = opcfind
Out = opcfind('P1',V1,'P2',V2,...)
Out = opcfind(S)
Description
Out = opcfind returns a cell
array, Out, of all existing OPC Toolbox objects.
Out = opcfind('P1',V1,'P2',V2,...)
returns a cell array, Out, of toolbox objects whose
property values match those passed as property name/property value
pairs, P1, V1, P2, V2,
etc.
Out = opcfind(S) returns
a cell array, Out, of toolbox objects whose property
values match those defined in structure S. The
field names of S are object property names and
the field values of S are the requested property
values.
Examples
Create some OPC Toolbox objects:
da1 = opcda('localhost','Dummy.ServerA');
da2 = opcda('localhost','Dummy.ServerB');
set(da1, 'Tag','myopcTag', 'Timeout',300);
grp = addgroup(da2, 'TestGroup');
itm = additem(grp, {'Dummy.Tag1', 'Dummy.Tag2'});Find all OPC Toolbox objects:
allObjCell = opcfind;
Find all objects with the Tag 'myopcTag':
myOPC = opcfind('Tag', 'myopcTag')Find all daitem objects:
itmCell = opcfind('Type', 'daitem')
