Abstract
In the ESO ELT control electronics guidelines, the hardware devices are located in standard COTS cabinets, each equipped with an air-liquid heat exchanger. In this paper a different architecture is explored, with the purpose of further exploiting the possibility of these devices to communicate remotely via EtherCAT. Advantages and drawbacks of this architecture are analyzed in terms of harness complexity, cabinets volume and mass, type of installation. Particular focus is given to the thermal requirement, with an analysis of the distributed architecture compliance with said requirement.
