Visualization Element 'Web Browser'

Symbol:

Tag: Special Controls

The element shows a website, PDF file, or video that has a URL.

Notice

The display options of the Web Browser element depend on the operating system and the display variant of the visualization.

Requirement: The software components of the web browser are available in the runtime and configured accordingly (example: videos to be shown on Linux).

Element name

Example: GenElemInst_59

Type of element

Web Browser

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

Note

You can also change the values by dragging the box symbols () 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 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

Note

You can also change the values by dragging the symbols () 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 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.

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 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.

Note

You can link the variables to a unit conversion.

Note

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.

Note

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

Element property 'Control variables'

URL

URL of the web page that is displayed in the visualization.

  • Variable (STRING or WSTRING)

    Example: PLC_PRG.stURL

  • Literal in single straight quotation marks

    Example: 'http://de.wikipedia.org'

Show

Variable (BOOL).

Example: PLC_PRG.bSetURL

Controls the display of the Web browser element.

If the variable contains a rising edge, then the visualization calls the web page given in URL and displays its contents in the 'Web browser' visualization element.

Back

Variable (BOOL).

Example: PLC_PRG.bGoBack

Controls the back navigation in the Web browser. If the variable has a rising edge, then the visualization displays the contents of the previously displayed page.

Forward

Variable (BOOL).

Example: PLC_PRG.bGoForward

Controls the forward navigation in the Web browser. If the variable has a rising edge, then the visualization displays the contents of the previously displayed page.

These properties are available only when you have selected the Preview: 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.
