RangeParameter

Model Setup / RangeParameter
Block Name: RangeParameter

Code File Location: VisualSim/data/expr/RangeParameter

Block Overview

• RangeParameter value of Int/Double/Long data type between a range to assure that the value for a parameter is not beyond acceptable values.
• The value of this variable cannot be modified during a simulation. The name can be called from any block field, another parameter or code lines. It can be modified, before the start of the simulation.  The parameter value can be modified in the Block Diagram, Simulation Cockpit Views or from the Batch-Mode script line. 

Description

RangeParameter is a variable containing a constant that can be of Int/Double/Long VisualSim data type between a specific range, function and/or a RegEx expression. The RangeParameter is defined by drag-n-drop action from the ModelSetup->RangeParameter Library folder into the Block Diagram.  The RangeParameter value and name must be updated before it can be used.  The parameter can be modified, prior to the start of each simulation. 

Double click of a RangeParameter provides 3 attributes; namely Value, Min and Max. Min and Max is to define the acceptable range, while Value is the value assigned to the parameter. If the user tries to assign value beyond Min and Max, then an exception is generated. For example; if Min is assigned with 10 and Max is assigned with 20; then Value cant be less than 10 and not greater than 20.

This RangeParameter name is available to the current window and all hierarchy blocks below this level.  The RangeParameter name can be accessed directly from lower-level hierarchy blocks, provided there is no intermediate parameter with the same name.  

The RangeParameter can be used in any Block fields, other parameters and in Virtual Machine code.   The RangeParameter name must be unique for each Block Diagram Window.

RangeParameters can be created for a Window, Hierarchical block and standard VisualSim library blocks. 

⇒Note: Illegal data values and values beyong specified range for the parameter will generate error messages.
