LABView's many built-in display routines allowed easy visualization of diagnostic and health-monitoring data during testing. Since LABView is built using block diagrams, the software naturally followed the designed control system's block and flow diagrams, and individual software blocks could be easily verified. Developing the software in LABView allowed the system to be flexible, understandable, and able to be modified by the end users. Software was developed in LABView to tie the sensors, operator interface, and mirror-control motors together. The control system, called the Segment Alignment Maintenance System (SAMs), utilized inductive sensors to measure the relative motions of the mirror segments. In order to improve the performance of the HET at the McDonald Observatory, a closed-loop system had to be implemented to keep the mirror segments aligned during periods of observation. The software development for an upgrade to the Hobby-Eberly Telescope (HET) was done in LABView.
