abstract = {At the Forschungszentrum Julich, an upgrade of the existing
distributed system for data acquisition (DAS) at the fusion
experiment TEXTOR94 is under development. DAS is currently
restricted to VAX/VMS and DECNET based communications, but
it is planned to add UNIX based systems, and to open the
local network for an improved wide area network access for
remote operations. Therefore, the DAS system is to be
equipped with a suitable client/server interface, which is
able to cope with the various computer platforms and
operating systems involved. For this purpose, the common
object request broker architecture (CORBA) will be used.
CORBA is an object oriented, standardized architecture for
distributed systems, which provides a high degree of
modularity in software design and allows for flexible
implementations. It is to act as a connecting link between
the existing system and new extensions. In order to provide
the desired client/server functionality for the data
acquisition tasks, the components of the system (diagnostic,
database, etc.) are modelled by CORBA interfaces. Processes
for diagnostic control and data readout in the existing
OpenVMS systems are aimed at to be accessible by CORBA
server implementations. The corresponding client
implementations will be developed for the operating system
platforms most frequently used at TEXTOR94. Communication
between clients and server will be based on TCP/IP and are
to be managed by CORBA. By this standardized way, remote
control of diagnostic instrumentation becomes possible in a
multiplatform computer and wide area network environment. At
a later stage it is intended to integrate the system into a
'virtual control room' environment, which should enable the
participation of cooperating institutions in the full
experimental program of TEXTOR94. (C) 1999 Elsevier Science
