Abstract

The Square Kilometre Array Observatory (SKAO) is an international organization that currently builds two multi-purpose radio telescope arrays. The SKA Low Frequency Telescope array (SKA Low), located in the Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory in Western Australia, with the observing range 50 - 350 MHz, will consist of more than 131,072 log-periodic antennas organized as 512 stations; the maximum distance between two stations is 65 kilometres. The SKA Mid Frequency Telescope array (SKA Mid), located in the Karoo region, Northwestern Cape province, South Africa, with the observing range 350 MHz - 15 GHz, will comprise 197 offset-Gregorian dishes; the dishes are 15 metres in diameter, the maximum baseline is 150 kilometres. This paper provides an overview of the automated attribute alarm handling in Tango Controls devices of the SKA Control System, the current software design for the early stages of the observatory, its horizontally scalable deployment, its integration and the lessons learned when real users and engineers deploy and use software.
