Visualization Element 'Meter 90°'

Symbol:

Tag: 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

Element name

Example: GenElemInst_1

Type of element

Meter 90°

Value

Variable (numeric data type)

The variable value determines the pointer direction of the element.

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 '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.

Own image

  • Image: ID of the background image.

    You select the background image from an image pool by clicking .

    Info: If you specify the value <default> or select the image from the Default category in the Input Assistant, then the original element background image is used.

  • Transparency color: Selection from list box or Input Assistant.

Element property 'Arrow'

Drop-down list for the alignment of the element

Additional arrow

: An additional arrow is shown inside the scale.

Element property 'Scale'

Element property 'Label'

Label

Selection list

  • Outside: Scale values are placed outside of the scale.

  • Inside: Scale values are placed inside of the scale.

Unit

Text that is displayed in the element.

Example: Units displayed in m/s.

Font

Font for labels (example: scale numbering).

Selection from the drop-down list or by clicking the button.

Scale format (C Syntax)

Values scaled in "printf" syntax

Examples: %d, %5.2f

Max. text width of labels

(optional) Value that redefines the maximum width of the scale label. The correct value is normally set automatically.

Note: Change this value only if the automatic adjustment does not yield the expected result.

Text height of labels

(optional) Value that redefines the maximum height of the scale label. The correct value is normally set automatically.

Note: Change this value only if the automatic adjustment does not yield the expected result.

Font color

Selection from the drop-down list or by clicking the button.

Element property 'Positioning'

Usage of

  • Preset style values: Values from the current style

  • User-defined settings: The subnode Positioning appears.

Positioning

Requirement: User-defined settings is selected as Usage of.

The displayed positioning settings depend on the type of needle instrument and Potentiometer, and partially on whether a custom background image is selected. The following settings are used for achieving the exact position relative to the background image.

Needle movement

Length of the needle (in pixels)

Scale movement

Distance from the tick marks to the center (in pixels)

Requirement: A customer image is selected as Background.

Scale length

Length of the tick marks (in pixels)

Requirement: A customer image is selected as Background.

Label offset:

Distance from the labels to the tick marks (in pixels)

Unit offset:

Distance of the unit text Label ‣ Unit from the upper scale edge (in pixels)

Origin offset

Offset of the element (in pixels)

Requirement: For the elements Meter 180° and Meter 90°, this property is displayed only if a custom image is selected as Background.

Element property 'Colors'

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.

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 Position ‣ Angle property, 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 X, Y, Rotation, and Interior rotation properties are supported by the "Client Animation" functionality.
