Visualization Element 'Slider'dl-permalink__symbolPermalink

Symbol:

_visu_img_slider

Category: “Common Controls”

The element changes the value of a variable, depending on the position of the slider within the slider bar. You define the value range of the slider bar by means of the scale start and scale end.

Element properties

“Element name”

Example: ‎Speed controller conveyor belt 1‎

Optional

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

“Type of element”

“Slider”

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.

“Variable”

Variable (numeric data type)

Example: ‎PLC_PRG.rSlider‎

When executed, the variable assigns a value that corresponds to the position of the slider in the bar.

“Page size”

Page size

  • As a fixed value, for example ‎10‎

  • As an IEC variable of data type integer

Requirement: The “Move to click” element property is not selected.

“Move to click”

Behavior of the slider at visualization runtime when it is clicked:

_cds_icon_option_activated: The slider moves to the clicked position.

_cds_icon_option_deactivated: The slider moves to the value (defined in the “Page size” element property) in the direction of the click.

Element property 'Scale'

“Show scale”

_cds_icon_option_activated: The element has a visible scale.

Note: This option is available for the “Slider” only.

“Scale start”

Least value of the scale and the lower limit of the value range for the element.

Example: ‎0‎

_visu_icon_variable: The property “Variable” is shown below.

“Variable”

Variable (integer data type). Contains the scale start.

Example: ‎PLC_PRG.iScaleStart‎

Declaration:

PROGRAM PLC_PRG
VAR
		iScaleStart : INT := 0;
END_VAR

“Scale end”

Greatest value of the scale and the upper limit of the value range for the element.

Example: ‎100‎

_visu_icon_variable: The property “Variable” is shown below.

“Variable”

Variable (integer data type). Contains the scale end.

Example: ‎PLC_PRG.iScaleEnd‎

Declaration:

PROGRAM PLC_PRG
VAR
		iScaleEnd : INT := 120;
END_VAR

“Main scale”

Distance between two tick marks on the rough scale.

Example: ‎10‎

_visu_icon_variable: The property “Variable” is shown below.

“Variable”

Variable (integer data type). Contains the distance.

Example: ‎PLC_PRG.iMainScale‎

Declaration:

PROGRAM PLC_PRG
VAR
		iMainScale : INT := 20;
END_VAR

“Subscale”

Distance between two dashes on the fine scale. You can hide the fine scale by setting the value to ‎0‎.

Example: ‎2‎

_visu_icon_variable: The property “Variable” is shown below.

“Variable”

Variable (integer data type). Contains the distance.

Example: ‎PLC_PRG.iSubScale‎

Declaration:

PROGRAM PLC_PRG
VAR
		iMainScale : INT := 5;
END_VAR

“Scale format (C Syntax)”

Formatting of the scale label (example: ‎%d %s‎)

Note: This property is available for the Slider only.

“Scale proportion”

Size of the scale (in %) of the total size

Element property 'Bar'

The property defines the representation of scaling and direction of travel.

“Diagram type”

The drop-down list varies depending on the alignment of the diagram.

Horizontal

  • “Top”: Scale is above the slider.

  • “Bottom”: Scale is below the slider.

  • “Top and bottom”: Two scales frame the slider above and below.

Vertical

  • ‎Left‎: Scale is left of the slider.

  • ‎Right‎: Scale is right of the slider.

  • ‎Left and right‎: Two scales frame the slider on the left and the right.

“Orientation”

Alignment of the slider; defined by the ratio of width to height.

  • “Horizontal”

  • “Vertical”

You can modify the alignment in the visualization editor by using the pointing device to adjust the width and height of the scrollbar.

“Running direction”

The drop-down list varies depending on the alignment of the slider.

Horizontal

  • “Left to right”: Scale starts at the left.

  • “Right to left”: Scale starts at the right.

Vertical

  • “Bottom to top”: Scale starts at the bottom.

  • “Top to bottom”: Scale starts at the top.

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.
