This example illustrates the use of a Program to manage a domain download into a control system as depicted in Figure A.1. The download requires the segmented transfer of control operation data from a secondary storage device to the local memory within a control system.

Figure A.1 – Program example

The domain download has a source and a target location which are identified when the download is initiated. Each time a segment of the domain is successfully transferred the Client is notified and informed of the amount of data that has been downloaded. The Client is also notified when the download is finished. The percentage of the total data received is reported periodically while the download continues. If the download fails, the cause of the failure is reported. At the completion of the download, the performance information is kept at the Server.
