Event
Archiving
 The event archive consists of data files recording all local
and remotely acquired time-stamped events, such as point alarms, alarm
acceptance, control actions, user login etc. This extensive archive is
backed up automatically daily and monthly by the system providing an unlimited
record of all recordable events and alarms on the system. In addition,
exported event data can be accessed via the SQL Events database.
Controls
  Digital and analogue controls may be performed by a privileged operator via summary displays
or mimic pages. Simply clicking on a controllable point with the mouse
brings up the control dialogue.
The operating privilege level for
performing controls is configured within the workstation, an operator must
be logged into an account with this privilege level or higher in order to
execute controls.
SQL Database
The SQL database tables form the heart of an extensive Information
Management System. These database tables are maintained in real-time by
the PC6-SQL export software. Import tables are used to provide
a conduit for privileged SQL and Web users to submit requests (controls,
set points etc.) and import new or modified archive data back into the
system. The system supports both Microsoft Access and/or Microsoft Sql
Server databases and provides access for both Web browser users and any
SQL based Microsoft compatible package (MS Access, MS Excel etc.).
 SQL Point Archive
The
SQL Archive database records all exported point archive and time-stamped
point archive data. Every archive sample is recorded in the SQL Archive
along with its time-stamp (to one second accuracy). This data forms part
of an unrestricted telemetry point archive on the system.
SQL Event Archive
The SQL Event database records all exported system, alarm
and control related event data. Every exportable event is recorded in
the appropriate SQL database table along with its time-stamp (to one second
accuracy). This data forms part of an unrestricted event archive on the
system.
SQL Access
 The SQL database
tables can be accessed by all SQL based Microsoft compatible packages
(MS Access, MS Excel etc.). Various proprietary data analysis and presentation
packages are also available. The supplied Software Development Kit (SDK)
provides support for SQL access and can be used to develop bespoke user
applications in any one of the five MS .NET Framework languages, including
Visual Basic, Visual C++ and Visual C#.
