Visualization Element 'ActiveX'dl-permalink__symbolPermalink

Symbol:

_visu_img_activex

Category: “Special Controls”

The element is used to link an existing ActiveX control in the visualization. You can configure the method calls and their parameters in the element properties of the “ActiveX” element.

Element properties

“Element name”

Example: ‎GenElemInst_1‎

“Type of element”

“ActiveX”

“Element”

Installed ActiveX component that is linked to the visualization.

Hint: To avoid typing errors, select the required ActiveX component by means of the Input Assistant.

Element property 'Position'

The position defines the location and size of the element in the visualization window. These are based on the Cartesian coordinate system. The origin is located at the upper left corner of the window. The positive horizontal x-axis runs to the right. The positive vertical y-axis runs downwards.

“X”

X coordinate of the upper left corner of the element

Specified in pixels.

Example: ‎10‎.

“Y”

Y coordinate of the upper left corner of the element

Specified in pixels.

Example: ‎10‎.

“Width”

Specified in pixels.

Example: ‎150‎

“Height”

Specified in pixels.

Example: ‎30‎

You can also change the values by dragging the box symbols (_visu_icon_position_element) to other positions in the editor.

Element property 'Center'

The properties contain fixed values for the coordinates of the point of rotation. This point of rotation is shown as the _visu_icon_center_point.png symbol. The point is used as the center for rotating and scaling.

“X”

X-coordinate of the point of rotation

“Y”

Y-coordinate of the point of rotation

You can also change the values by dragging the symbols (_visu_icon_center_point.png) to other positions in the editor.

Element property 'Absolute movement'

The properties contain IEC variables for controlling the position of the element dynamically. The reference point is the upper left corner of the element. In runtime mode, the entire element is moved.

“Movement”

“X”

Variable (numeric data type). Defines the X position (in pixels).

Example: ‎PLC_PRG.iPos_X‎.

Increasing this value in runtime mode moves the element to the right.

“Y”

Variable (numeric data type). Defines the Y position (in pixels).

Example: ‎PLC_PRG.iPos_Y‎.

Increasing this value in runtime mode moves the element downwards.

“Rotation”

Variable (numeric data type). Defines the angle of rotation (in degrees).

Example: ‎PLC_PRG.iAngle1‎.

The midpoint of the element rotates at the “Center” point. This rotation point is shown as the _visu_icon_center_point.png symbol.

In runtime mode, the alignment of the element remains the same with respect to the coordinate system of the visualization. Increasing the value rotates the element to the right.

 _visu_img_prp_rotation

“Scaling”

Variable (integer data type). Causes centric stretching.

Example: ‎PLC_PRG.iScaling‎.

The reference point is the “Center” property.

The value ‎1‎ shrinks the element by a factor of ‎0.001‎. The value ‎1000‎ returns the element to its original size.

“Interior rotation”

Variable (numeric data type). Defines the angle of rotation (in degrees).

Example: ‎PLC_PRG.iAngle2‎.

In runtime mode, the element rotates about the point of rotation specified in “Center” according to the value of the variable. In addition, the alignment of the element rotates according to the coordinate system of the visualization. Increasing the value in the code rotates clockwise.

The rotation point is shown as the _visu_icon_center_point.png symbol.

Note: If a static angle of rotation is specified in the property “Position  Angle”, then the static angle of rotation is added to the variable angle of rotation (offset) when the visualization is executed.

 _visu_img_prp_inner_rotation

You can link the variables to a unit conversion.

The properties “X”, “Y”, “Rotation”, and “Interior rotation” are supported by the "Client Animation" functionality.

Element property 'State variables'

The variables control the element behavior dynamically.

“Invisible”

Variable (‎BOOL‎). Toggles the visibility of the element.

‎TRUE‎: The element is not visible at runtime.

The “Invisible” property is supported by the "Client Animation" functionality.

Element property 'Initial calls'

These method calls are executed during initialization. They are executed in the first cycle only.

“Method calls ”

Button '“Create new”'

Creates a subnode below “Methods” with parameters for the method call.

“Methods”

“[<number>]”

  • “Method”: Name of the method

  • “Parameter”: Parameter passed at the method call

  • “Result parameter”: Optional variable for the return value of the method

Element property 'Cyclic calls'

These method calls are executed in every cycle. They are executed in the refresh rate of the visualization.

“Method calls ”

Button '“Create new”'

Creates a subnode below “Methods” for a method call and its parameters.

“Methods”

“[<number>]”

  • “Method”: Name of the method

  • “Parameter”: Parameter passed at the method call

  • “Result parameter”: Optional variable for the return value of the method

Element property 'Conditional calls'

These method calls are executed in the refresh rate of the visualization. You define the call condition in the property “Methods  [<number>]  Call condition”.

“Method calls ”

Button '“Create new”'

Creates a subnode below “Methods” with a call condition and parameters for the method call.

“Methods”

“[<number>]”

  • “Method”: Name of the method

  • “Call condition”: Variable (‎BOOL‎). A rising edge of this variable triggers the call of this method.

  • “Parameter”: Parameter passed at the method call

  • “Result parameter”: Optional variable for the return value of the method

These properties are available only when you have selected the “Support client animations and overlay of native elements” option in the Visualization Manager.

“Animation duration”

Defines the duration (in milliseconds) in which the element runs an animation

  • Variable (‎integer value‎)

    Example: ‎Menu.tContent‎ with ‎VAR tContent : INT := 500; END_VAR‎

  • Integer literal

    Example: ‎500‎

Animatable properties

  • “Absolute movement”, “Movement”, “X”, “Y”

  • “Absolute movement”, “Rotation”

  • “Absolute movement”, “Interior rotation”

  • “Absolute movement”, “Exterior rotation”

The animated movement is executed when at least one value of an animatable property has changed. The movement then executed is not jerky, but is smooth within the specified animation duration. The visualization element travels to the specified position while rotating dynamically. The transitions are smooth.

“Move to foreground”

Moves the visualization element to the foreground

Variable (‎BOOL‎)

Example: ‎bIsInForeground‎ with ‎VAR bIsInForeground : BOOL := FALSE; END_VAR‎

‎TRUE‎: At runtime, the visualization element is displayed in the foreground.

‎FALSE‎: At runtime, the visualization element is displayed in the layer where it was inserted in the visualization editor.

Element property 'Access rights'

Requirement: User management is set up for the visualization.

“Access rights”

Opens the “Access rights” dialog. There you can edit the access privileges for the element.

Status messages:

  • “Not set. Full rights.”: Access rights for all user groups : “operable”

  • “Rights are set: Limited rights”: Access is restricted for at least one group.
