Abstract

The Multiconjugate adaptive Optics Relay for ELT Observations (MORFEO), and adaptive optics module being developed for the ESO Extremely Large Telescope, has officially entered the Final Design phase. The control electronics functions, power and network distribution, system management and monitoring are all part of the MORFEO Instrument Control Hardware. It is based on industrial COTS components, and most of its functions are managed through the use of a PLC-based architecture. The EtherCAT protocol also allows great flexibility in the choice of the PLC modules topology. This proves especially useful for MORFEO, as its control electronics cabinets are distributed in different locations, due to the limited space available on the Nasmyth Platform. The industrial elements also present many additional advantages: among them, a quick update of the components during the life of the telescope, useful support from the providers in their implementation, easy procurement of spare parts, and a more accurate reliability analysis of the whole system. This paper describes the current, up-to-date design of the Instrument Control Hardware and the general ruels developed for the design of each MORFEO subsystems control electronics, in order to optimize the architecture while in compliance with ESO requirements. Finally, an overview of the expected steps that will be taken to bring all aspects of the overall design to a Final Design maturity level is given.
