| Abstract | The control software for the Very Large Telescope follows the “Standard Architecture ” and is distributed over several workstations, that provide high-level and coordination services, and VME based systems, for real-time control purposes. The adoption of object-oriented design techniques and the support of a C++ application framework for the implementation of Event-Driven systems reduces considerably the complexity of the applications. The framework provides a general application skeleton and services to automatically receive and analyse events. These are then dispatched to specialized objects, designed to handle specific events. Since all the run-time and configuration data of the whole VLT is stored in a distributed real-time database, there is a strict coupling between the structure of the database and the applications. As a consequence, the real-time database, although based on the hierarchical model, has been structured to provide support for object-oriented design and implementation. This paper describes the architecture of the Telescope Control Software (TCS) for the VLT and the object-oriented infrastructure on which it is based. 1 |
