Visualization Element: Meter 90°

Symbol:

_visu_img_meter_90.png

Category: Measurement Controls

The element displays the value of a variable. The needle is positioned according to the value of the assigned variable. A meter is used to represent a tachometer, for example.

Element properties

Are all element properties available?

All properties are available only after you select the Advanced option or the All categories filter in Properties.

Element name

Example: GenElemInst_1

Tip

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

Element Type

Meter 90°

Value

Variable (numeric data type)

The variable value determines the pointer direction of the element.

Center

The properties contain fixed values for the coordinates of the point of rotation. The rotation point is displayed in the editor as the _visu_icon_center_point.png symbol and is used as the center for rotation and scaling.

Tip

You can also change the values by dragging the _visu_icon_center_point.png symbol to another position in the editor.

X

X-coordinate of the point of rotation

Y

Y-coordinate of the point of rotation

Absolute movement

The properties can be assigned to IEC variables for controlling the position of the element dynamically. The reference point is the upper left corner of the element. At runtime, the entire element is moved.

Movement

X

  • Variable (numeric data type) for the X-position (in pixels)

    Example: PLC_PRG.iPos_X

Increasing this value at runtime moves the element to the right.

Y

Increasing this value at runtime moves the element downwards.

Rotation

Variable (numeric data type) for 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.

At runtime, 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) for the angle of rotation (in degrees)

Example: PLC_PRG.iAngle2

At runtime, 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.

Tip

You can combine the variables to a Unit conversion.

Tip

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

Animation

Tip

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

Variable for 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

Variable (BOOL) for setting the element in the foreground

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.

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

Position

The position defines the location and size of the element in the visualization window. This is based on the Cartesian coordinate system. The origin is located in the upper left corner of the window. The positive horizontal X-axis runs to the right. The positive vertical Y-axis runs downwards.

X

The X-coordinate (in pixels) of the upper left corner of the element

Example: 10

Y

The Y-coordinate (in pixels) of the upper left corner of the element

Example: 10

Width

Specified in pixels

Example: 150

Height

Specified in pixels

Example: 30

Tip

You can change the values by dragging the box _visu_icon_position_element.png symbols to other positions in the editor.
