The ARIEL Instrument Control Unit (ICU) implements the monitoring, control, and commanding of both the ARIEL IR Spectrometer (AIRS) and Telescope Control Unit (TCU). It acquires the AIRS scientific data provided by the AIRS detector control units and implements the onboard pre-processing and downlink to the satellite Mass Memory. Based on a preliminary Technical Specification, a high-level preliminary software architecture has been produced. In this paper we provide the ARIEL ICU Application SW layers description and some examples of the static and dynamic diagrams that will be included in the final architecture
