Abstract

The Frascati Tokamak Upgrade (FTU) continuous (slow) data acquisition system has been redesigned to allow easy monitoring of the status of the plant. In the new system "Opto22™" modules, which use Ethernet as fieldbus, substitute the old "programmable logic controller (PLC)" devices allowing easy access to and display of many continuous measurements. Data collected by "Opto22" modules are stored in a "MySQL" database via a driver written in C++ language. A "CORBA" server, running on the same machine hosting the "MySQL" server, allows the database access from any remote client regardless of the local platform. A remarkable aspect looks out for the use of totally free software packages. This new architecture overcomes the limitations of the previous monitoring system:an interface based on internet browser allows to easily configure Opto22 modules and MySQL database;a graphical interface, developed in Java, allows data management and visualization;the above operations are completely platform independent. In addition the CORBA server introduces the advantages of:hardware independence, thus allowing maximum flexibility in the choice of platforms and system components;both network and programming languages being completely transparent. This paper will present the new system architecture, last results and future developments. © 2005 Elsevier B.V. All rights reserved.
