The Data Acquisition and Control Systems for ATF:an Overview

A data acquisition and control system is being developed to support the Advanced Toroidal Facility (ATF) at the Oak Ridge National Laboratory (ORNL). This system has two separate elements: a VAX-based data acquisition and management system and a status and control system that uses programmable logic controllers (PLCs). Although these systems can operate independently, they are intended to cooperate fully and complement one another. This paper presents an overview of the hardware components, software architecture, and operations of these systems.
