Evaluation Editor View

The Evaluation Editor view allows you to create animated graphics by configuring and applying expressions and substitutions to the properties of an element and associated data point properties.

Expression Section

Evaluation Editor
	Description
Expand/Collapse Button	Expand and collapse the Evaluation Editor view.
Property	Select from a list of properties in the drop-down menu. The properties listed are all associated with the active element or object on the canvas. The property selected is affected by the evaluation.
Type	Select and display the type of evaluation to apply to the selected element property.
	Clear Empty all the fields in the Evaluation Editor, except for the Property field. The Type field is reset to Simple. Use this if you want to recreate an evaluation.
	Enable\Disable Evaluation Select the check box to enable the current evaluation or, deselect this check box to disable the evaluation. Use this during testing, if you want to temporarily disable an evaluation.
Value	Displays the current value used to manipulate the associated graphic object or data point. This is a read-only field: Displays the current value of the property in Test and Runtime mode. In Design mode, the value displayed is the current value of the element property in the Property Viewer.
	Previous and Next Arrows Select previous or next arrow to scroll through recently created evaluations associated with the active element on the canvas. The arrows are only visible if there are existing evaluations associated with the active element.
Expression	The path, data point name and property that is being evaluated. The value or result is applied to the property being evaluated. The data point property value can be derived from one of the following: value string literal data point s JavaScript command The path and property name of the data point whose value is applied to the property evaluation. The path of the data point displays using the data point “Names” setting. (See System Browser) The data point’s default property value is used, if none is specified in the path. For example, the following is the path to data point `AI_1`: `System1.ManagementView:ManagementView.FieldNetworks.BACnetNetwork_1.Hardware.TECDevice_1.Local_IO.`AI_1; The default property above is .Present_Value. To specify a specific data point property, type “`.Property_Name`” at the end of the data point path, after the “`;`”. For example, `System1.ManagementView:ManagementView.FieldNetworks.BACnetNetwork_1.Hardware.TECDevice_1.Local_IO.AI_1;.`Limit_Enable To find out what properties are associated with the currently selected data point, navigate to the Extended Operations tab in System Manager.
Type	Allows you to select which information from the data point or source in the Expression field, you want to display in the Result field. The options are as follows: Reference (Default) - The COV value of the data point. Function - The Function name of the data point reference. Object Model - The object model name of the data point reference. Script - Returns a result based on JavaScript(TM) expressions entered.
Result:	Display the result of the expression using the value type of the source. The data type of the expression result is always the type of the expression. This value is mapped to the property type.

Evaluation Editor Tools Menu

Evaluation Editor Tools Menu
	Description
Condition Order	Organize the conditions in order of preference. Only applies to Animated, Discrete, and Linear evaluations.
Delete Condition	Delete a condition.
New Condition	Add a new condition to the list. Only applies to Discrete and Linear evaluations.

Linear Evaluation Editor Section

Linear Evaluation Fields
	Description
Range	Display the minimum and maximum range applied to the expression value. If the expression value falls below the Min value, then the associated Value is applied to the property evaluated. If the expression value is higher than the Max range, than that Value is applied to the property.
Value	Display the value associated with Min and Max fields determine how the property displays in the graphic.
Auto Range	If checked, the Min and Max value range from the expression is applied. If one of the Min or Max values is left blank, then the corresponding minimum or maximum range is taken from the expression range.

Discrete Editor Evaluation Section

Discrete Evaluation Fields

Description

Condition

Display a range or threshold, when met by the expression result, applies the associated Value to the property evaluation.

Multiple conditions are supported.

Animation Editor Evaluation Section

Animated Evaluated Fields
	Description
Frame	The frame number.
Value	The value that is applied to the expression result during that frame interval.
Animation Interval	The interval time between frames in mille-seconds when animated. The value must be greater than or equal to 100.

Multi Evaluation Editor Section

Multi Evaluated Fields
	Description
Condition	Associates one check box per expression, indicating whether an expression is true, false, or unspecified. If a condition is true, the associated Value is applied from left (top) to right (bottom) expression. One check box per expression displays for each condition.
Value	If checked, the enumerated values of a property type display with the property value in the Discrete and Linear Value field.
