Variable history
You can make CalcExpress maintain a history of desired variables. It will collect values
assigned to a variable together with timestamps in the history's circular buffer according
to specified history parameters. History values can then be retrieved in a few provided
ways. CalcExpress includes set of basic VIs to manage variable histories and set of VIs
that help you build data logging applications.
Aliases
You can associate an alias with a variable and use it to access the variable in VIs and
scripts. The advantage of using aliases is simple access to variables residing in
arbitrary contexts; furthermore, the syntax of an alias name is less strict than the
syntax of a variable name.
Variable Manager VIs
New VIs give you more control over variables and variable contexts, and provide extended
information on them.
CalcExpress functions
New CalcExpress functions give you capability to operate on aliases and variable histories
in a script.
New probe functions have implementation that makes it possible to use them in executable
programs.
Error handling
CalcExpress 2.4 uses new method of error handling and messaging. In order to identify an
error more strictly, it uses own set of the fixed error codes. In addition, you can
specify a custom error code in your FuncVI. CalcExpress VIs will return this code if the
FuncVI function finishes with an error.
VarMan Spy utility
New VarMan Spy has modern user interface and gives you full control over variables and
their properties. Furthermore, it can now be embedded into an executable program in order
to investigate and control working parameters of the program at runtime.
CESP ISP utility
New ISP (Interactive Script Processor) has innovations that make your work more
productive. You can open as many ISP windows as you need and work with them in parallel.
You can even execute several scripts at the same time. It has also options that simplify
script debugging with the help of VarMan Spy.
Compatibility
CalcExpress 2.4 is compatible with LabVIEW 7.
