Ground Based and Airborne Instrumentation for Astronomy VI, DOI: 10.1117/12.2231890
With the steadily increasing complexity of scientific instruments, there is an ever-growing demand for improved control electronics. This is especially important for infrared instruments, where the challenging vacuum and cryogenic systems increase the demands on the overall control system. The control electronics must monitor and adjust many different subsystems in different locations, some mounted at the telescope and others placed inside the telescope building. To implement these different demands, a comprehensive Interlock system with process visualization and powerful diagnostics has been developed for the CARMENES instrument at the Calar Alto Observatory.
