Abstract

Interlock and safety systems (ILS) play a significant role in the safe and reliable operations of cyber-physical systems such as optical telescopes. We performed a comprehensive hazard analysis to identify and classify various hazard issues and their severities together with the required actions. ILS has been deployed in reliable PLC platforms in the INO340 telescope to deliver all related functionalities in safe and stable conditions. Since ILS provides dedicated engineering panels for specific operators, we have also developed a specific Alarm/warning management system for the operator/astronomer applications in parallel. In this paper, we briefly present the INO340 telescope hazard analysis process, ILS architecture and development methodologies, and Alarm/warning management system design and implementation.
