OPCApply — applies changes to an outgoing connection.
(OPCApply [label])
label
The name for this connection, as displayed in the OPC option of the Properties
window. If label is * or
absent, then the command affects all currently configured
connections.
A message indicating success or error. Please refer to Return Syntax for details.
This command applies any changes made to an outgoing OPC connection specified
by label. The only changes that are not immediately
applied are OPCAddItem and OPCRemoveItem.
Therefore, you can call OPCAddItem and
OPCRemoveItem multiple times and then must issue
OPCApply once for the changes to take effect.
