A Database SQL Query (or SQL Query for short) is interpreted
dynamically at runtime.
enabling different Queries to be run for varying situations however, the
SQL Text has to be compiled on the fly every time it is executed and
consequently is less efficient than a Server Query.
DBCS stands for Double Byte Character Set and is a Microsoft extension
of ASCII which uses 2 bytes (16 bits) to define character codes. With this
larger range it can include accented characters, extended ASCII characters,
Nordic characters and symbols.
DCOM is a distributed version of COM that allows components on
different PCs to interact over a network.
Dynamic Data Exchange.
correctly prepared programs can actively exchange data and control other
applications within Microsoft Windows.
SCADA applications are created and tested using the development
environment within CX-Supervisor.
application can be delivered as a final customer application to be run by
the run-time environment.
Dynamic Link Library. A program file that although cannot be run stand-
alone as an executable, can be utilised by one or more applications or
programs as a common service.
DLL's comprise a number of stand-alone functions. In CX-Supervisor, a
DLL containing icons can be accessed to represent the display part of an
OLE object. One such DLL, 'MORICONS.DLL', is provided in the
standard Microsoft Windows installation.
A recipe is downloaded during runtime. This process involves identifying
the appropriate recipe and executing the validation code, if any exists. The
download is complete when each ingredient has set its point to the target
value.
A file that contains programs or commands of an application that can be
executed by a user or another application. Executable files have a *.EXE
file extension. CX-Supervisor provides two executable files, one for the
development environment (CXSUPERVISORDEV.EXE), and one for the
run-time environment (SCS.EXE).
In the CX-Supervisor script language, expressions are a construct for
computing a value from one or more operands.
example "lift = height + rate", the expression is "height +
rate" where the result yielded from the expression is used for the value
of "lift". Outside of the script language, expressions consisting of
operators and operands can be used to control objects , through actions.
The SQL Text can be modified at runtime,
Now obsolete. A channel through which
On completion, the finished
DLL files have a *.DLL extension.
