Visualization Element 'Webbrowser'
Tag: Special controls
The element shows a website, PDF file, or video that has a URL.
Notice
The display options of the Webbrowser 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 system and configured accordingly (example: videos to be shown on Linux).

Type of element |
Webbrowser |
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.

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.

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 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 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.
|
|
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 select the Preview: Support client animations and overlay of native elements option in the Visualization Manager.
You can animate a movement, a rotation, and the visibility of a visualization element.
|
Animation time |
Time that the element executes an animation (in milliseconds) Example: 500 |
|
Move to the foreground |
Property value (BOOL) TRUE: At runtime, the element is displayed in the foreground. FALSE: At runtime, the element is displayed in the layer where it was inserted in the visualization editor. |
