The Line-Side display was used to quickly display conformance to defined tolerances to assembly line workers. It consisted of two seperate programs; the Data Manager and the Graphical Annunciation Screen. The Data Manager received data from vision Gauges via OPC messages. It then sent that value and the current tolerances for the point to the Graphical Annunciator via Microsoft Message Queue. The Annuncuator then displayed the setting as red / Yellow / Green depending on how close the measurements was to the ideal value.
