dOPC Client Toolkit

Areas contains an area filter, which means that only events of the specified areas will be reported.

property Areas: TStrings;
__property TStrings Areas;

If this string list is empty, the events of all areas will be reported. If you modify this collection while the control is connected to an OPC server, you need to call the Refresh method to apply the changes.

var Filter : tdOPCEventFilter; begin Filter := dOPCEventServer1.Filter[0]; //get first filter Filter.Areas.Clear Filter.Areas.Add('Area 1') Filter.Areas.Add('Area 2') Filter.Refresh; end;
