Example: GenElemInst_1

Type of element

Potentiometer

Variable

Variable (numeric data type). Contains the position of the pointer for the potentiometer.

A visualization user can modify the value by dragging the pointer to another position.

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 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.

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

Note

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

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.png 

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.png 

Note

You can link the variables to a unit conversion.

Note

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