Title
Distributed Control System for the Test Interferometer of the ALMA Project
Abstract
The control system (TICS) for the test interferometer being built to support the development of the Atacama Large Mil- limeter Array (ALMA)(1) will itself be a prototype for the final ALMA array, providing a test for the distributed con- trol system under development. TICS will be based on the ALMA Common Software (ACS)(2) (developed at the Eu- ropean Southern Observatory), which provides CORBA- based(3) services and a device management framework for the control software. Simple device controllers will run on single board com- puters, one of which (known as an LCU) is located at each antenna; complex, compound device controllers may run on centrally located computers. In either circumstance, client programs may obtain direct CORBA references to the devices and their properties. Monitor and control re- quests are sent to devices or properties, which then pro- cess and forward the commands to the appropriate hard- ware devices as required. Timing requirements are met by tagging commands with (future) timestamps synchronized to a timing pulse, which is regulated by a central reference generator, and is distributed to all hardware devices in the array. Monitoring is provided through a publish/subscribe CORBA-based service.
