TiVCLComponent.OPCItemUpdateSuspend
TiVCLComponent
Used to instruct the connected OPC Server to suspend sending updates to the
component without disconnecting from the OPC Server.
procedure OPCItemUpdateSuspend(Index: Integer);
Description
Use OPCItemUpdateSuspend to instruct the connected OPC Server to suspend
sending updates to the component without disconnecting from the OPC Server.
This method is useful if you simply want to temporarily suspend the sending of
update by the OCP server without going through the overhead associated with
deactivating and then reactivating the OPC connection. To resume updates from
the OPC Server, call OPCItemUpdateResume.
Example
Delphi
iComponent.OPCItemUpdateSuspend(0); //Suspends Updates for the 1st OPC Item
C++ Builder
iComponent->OPCItemUpdateSuspend(0); //Suspends Updates for the 1st OPC Item
Note: The Index value is 0 based.
