<p>If you look at the last paragraph of the following webpage, you will see how National Instruments used the LabVIEW DataLogging and Supervisory Control (DSC) module for their headquarter's building automation.
http://www.ni.com/opc/opc_resources.htm Echelon Lonworks was used to communicate with Siebe controllers via an OPC Server. I believe the OPC Server for LonWorks was from GesyTec: http://www.gesytec.de/englisch/products/easylon/el_opc-server.htm The LabVIEW-DSC module comes with built-in OPC support, tag management, alarms, security, and is geared towards applications with a high channel count. You may want to evaluate if this is a good fit for your application: http://www.ni.com/labviewdsc Regards, <i>Khalid</i><p>
