| Resumo | |
The ASTRI project (Astrofisica con Specchi a Tecnologia Replicante Italiana) led by INAF (Italian National Institute of Astrophysics) was created to study astronomical sources that emit gamma rays at very high energies. The ASTRI MiniArray project involves the construction and installation of nine Cherenkov telescopes at the Teide Observatory (Spain), three of which have been constructed thus far. This document concerns the development of the low-level software for the control of the remaining six telescopes forming part of the project. The logic to be implemented will be derived from the existing software on the ASTRI-Horn prototype telescope installed on Mount Etna as well as from what was created by INAF on the already existing ASTRI Mini-Array telescopes. The control system of each of the six telescopes is called TCU (Telescope Control Unit) and will be developed on a Beckhoff PLC, using the TwinCAT development environment. The TCU will generate the pointing trajectories, control the telescope's movement, and enable the execution of every procedure required for the maintenance, testing, and calibration of the telescope control system. The TCU will also supervise all of the telescope's sub-devices, such as the camera and power supplies, and will manage I/O signals of the interlocks and the logic of the safety procedures in collaboration with a Beckhoff safety PLC. It will also monitor all parameters related to the movement and status of hardware devices. The low-level control system will interface with the high- level TCS (Telescope Control System) software through a standard OPC-UA (Open Platform Communications - Unified Architecture) server, allowing the supervision and command of all equipment connected to the PLC.
