<title>TNG control system software architecture improvement</title>

Abstract

The axes control of a modern telescope such as TNG requires a large amount of software in order to manage the complex control hardware. The low level software is always the most difficult to develop and test since its behavior strictly depends on the physical device, and theoretical solutions often reveal not applicable. Simulation is precious but field tests are in this case absolutely necessary. This paper overviews the main components of the TNG axes control software, refined and tested on the field.
