The software for slow-control of
accelerator systems
should allow:
Monitoring of system parameters
Timely alerting to off-optimum situations in equipment performance
Saving data into the database for their future analysis and processing
should consider:
Specialized and even non-standard equipment
Variety of hardware interfaces
Distance between the connected equipment and the operator
Use of mathematical methods of data analysis and processing (including
on-line)
Necessity of on-line and off-line access to the data , including through Web
Methods of slow-control accelerator
system software development
Traditional programming
Following problems may evoke:
high labor costs at every level of application development
absence of a common solution platform
passing the developed software to other programmers for
support
SCADA usage
SCADA help resolve the main part of these problems for they
comprise a set of interrelated components allowing for
simplification and unification of software development
procedures.
The development of slow-control system software for the LUE200 accelerator was implemented in the LabView+DSC
environment.

The server-to-client application and
conversely data transmission is
implemented using Tag-Engine

Alarms storage
Event storage
The initial settings of database record conditions and rate are
defined in the configuration file
The data stored in the DB may be accessed using historical
trends, SQL-queries, and ODBC-compliant applications
(Microsoft Query, Microsoft Access, or Microsoft Excel).
