opcreset - Disconnect and delete all OPC Toolbox objects
Syntax
opcreset
opcreset -force
Description
opcreset disconnects and
deletes all OPC Toolbox objects. This command flushes any data
stored in the buffer, cancels all asynchronous operations, and closes
any open log files.
You cannot reconnect a toolbox object to the server after you
delete the object. Therefore, you should remove these objects from
the workspace with the clear function.
Note that you cannot call opcreset if an opctool session
is open, or if Simulink models containing OPC Toolbox blocks
are open. Close all opctool sessions and all open Simulink models
containing OPC Toolbox blocks before calling opcreset.
opcreset -force closes all
open opctool sessions and all Simulink models
containing OPC Toolbox blocks, without prompting to save those
sessions and models. If you use the -force option,
you lose any unsaved changes to those sessions and models. Use the -force option
only as a last resort.
Examples
Create an opcda object, and add a group to
that object. Then delete the OPC Toolbox objects using opcreset,
and clear all variables from the workspace.
da = opcda('localhost','Dummy.Server');
grp = addgroup(da);
opcreset; % Deletes all objects
% Clear the variables
clear da grp
