	Monitoring and control solutions for large one-off systems are typically built in silos using multiple tools and technologies. Functionality such as data processing logic, alarm handling, UIs, device drivers are implemented by manually writing configuration code in isolation and their cross dependencies maintained manually. The correctness of the created specification is checked using manually written test cases. Non-functional requirements – such as reliability, performance, availability, reusability and so on – are addressed in ad hoc manner. This hinders evolution of systems with long lifetimes. For ITER, we developed an integrated specifications environment and a set of tools to generate configurations for target execution platforms, along with required glue to realize the entire M&C solution. The SKA is an opportunity to enhance this framework further to include checking for functional and engineering properties of the solution based on domain best practices. The framework includes three levels: domain-specific, problem-specific and target technology-specific. We discuss how this approach can address three major facets of complexity: scale, diversity and evolution.

The Monitoring and Control system for the SKA radio telescope is now moving from the conceptual design to the system requirements and design phase, with the formation of a consortium geared towards delivering the Telescope Manager (TM) work package. Recent program decisions regarding hosting of the telescope across two sites, Australia and South Africa, have brought in new challenges from the TM design perspective. These include strategy to leverage the individual capabilities of autonomous telescopes, and also integrating the existing precursor telescopes (ASKAP and MeerKat) with heterogenous technologies and approaches into the SKA. A key design goal from the viewpoint of minimizing development and lifecycle costs is to have a uniform architectural approach across the telescopes, and to maximize standardization of software and instrumentation across the systems, despite potential variations in system hardware and procurement arrangements among the participating countries. This paper discusses some of these challenges, and their mitigation approaches that the consortium intends to work upon, along with an update on the current status and progress on the overall TM work.
