Tag[another tag]. Arrays simplify many configurations and permit the use of multiplexing in
screens, recipes, and communication interfaces. Also, it saves development time during the tag
declaration.
Indirect tags (pointers): Use of the @Tag construct causes an indirect read or write. For
example, if the X tag has the value “Setpoint” and you use the @X construct, then you are
reading or writing value of the tag Setpoint. You can use @Tag wherever you use a tag name,
such as the name of a pen in a trend graph.
Classes: You can define a data structure such as: ClassPID { PV, CV, SET, KP, KI, KD } and
declare tags or even arrays of the type ClassPID that will have groups of values instead of a single
value.
You can even combine all tags features (array, pointer and classes) - For example: @Tag[another
tag] or Tag[another tag].SP.
Mathematical functions
InduSoft Web Studio has an internal programming language used for writing logical relationships
and mathematical calculations needed in applications programs.
Online configuration
The runtime tasks accept new configurations immediately and without the need to restart or
recompile the programs. You can change any element in the configuration, including
mathematical calculations, reports, addresses in the PLC, and the type of a tag in the database. All
these changes can take place on the fly, without halting the application or your process. You can
also run an emulation of the application on your development computer and test it before
downloading to the target runtime station.
Easy addition of symbols
Reusable objects or groups of objects that you store for reuse are known as symbols. In a few
seconds you can add a new symbol or modify an existing symbol, which allows you to quickly
reuse symbols as you build your application.
Report generation
InduSoft Web Studio has all the tools you need to generate and save to disk reports that contain
text and graphics, without requiring the use of other software packages such as Microsoft Excel.
Recipes in ASCII
The InduSoft Web Studio database supports direct access to recipe files written in ASCII.
DDE, NetDDE, ODBC and OPC (on Windows NT, Windows 95)
The product provides DDE, NetDDE, and OPC as well as the ODBC interface for access to
relational databases on the Windows NT/2000 runtime. Windows CE also supports the interface
OPC.
