Visualization Element 'Image Switcher'dl-permalink__symbolPermalink

Symbol:

_visu_img_image_switcher

Category: “Lamps/Switches/Bitmaps”

The element displays one of three referenced images. Mouse actions change the displayed image. The images are defined in the “Image settings” element properties. The effects of mouse clicks are defined in the “Element behavior” property.

Element properties

“Element name”

Optional

Hint: Assign individual names for elements so that they are found faster in the element list.

Example: ‎ImageSwitcher_1‎

“Type of element”

“Image Switcher”

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.

“Variable”

Variable (‎BOOL‎).

The value of the variable changes according to user input and it is independent of the “Element behavior” element property.

Image settings

“Image "on"”

Image ID from an image pool. The image can be selected using the input assistant.

The image is used if the variable of the “Variable” property has the value ‎TRUE‎.

“Image "off"”

Image ID from an image pool. The image can be selected using the input assistant.

The image is used if the variable of the “Variable” property has the value ‎FALSE‎.

“Image "clicked"”

Image ID from an image pool. The image is selected using the input assistant.

In runtime mode, the visualization displays the referenced image when the element is clicked (and the mouse button is held down).

Requirement: The “Element behavior” is “Image toggler”.

“Transparency”

_cds_icon_option_activated: The “Transparent color” is selected.

“Transparent color”

The image pixels that have the transparent color are displayed as transparent.

Requirement: “Transparency” is activated.

  • _cds_icon_three_dotsThe “Color” dialog box opens.

  • _cds_icon_arrow_down: A drop-down list with color names opens.

“Scaling type”

Defines how an image fits in the element frame.

  • “Fixed”: The original size of the image is retained, regardless of the dimensions of the element.

  • “Isotropic”: The entire image is shown in the element frame, either larger or smaller. As a result, the proportion of height and width are retained.

  • “Anisotropic”: The image resizes automatically to the dimensions of the element frame, filling the entire element frame. As a result, the proportions are not retained.

“Horizontal alignment”

Horizontal alignment of the image within the element frame or element

  • ‎Left‎

  • ‎Centered‎

  • ‎Right‎

Requirement: “Scaling type” is “Isotropic”.

“Vertical alignment”

Vertical alignment of the image within the element frame or element

  • ‎Top‎

  • ‎Centered‎

  • ‎Bottom‎

Requirement: “Scaling type” is “Isotropic”.

“Element behavior”

  • “Image toggler”: Every mouse click switches the image.

  • “Image tapper”: While a visualization user holds down the mouse button, the image of the “Image on” property is displayed. At the same time, the value ‎TRUE‎ is assigned to the “Variable” property.

“Tap FALSE”

_cds_icon_option_activated: While the mouse button is pressed, the image of the “Image” property is displayed and the “Variable” property gets the value ‎FALSE‎ instead of the value ‎TRUE‎, and back.

Requirement: “Image tapper” is selected in the “Element behavior” property.

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 'Texts'

“Tooltip”

String display as tooltip for the element

Example: ‎Valid access‎.

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

“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 “Position  Angle” property, 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 “X”, “Y”, “Rotation”, and “Interior rotation” properties 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.

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

“Deactivate inputs”

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

‎TRUE‎: User inputs do not have any effect in runtime more. The element is shown as deactivated.

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

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.
