Objects and groups can be moved up and down during runtime, changing dynamically whenever the value of a particular expression changes. By default, as the value of the expression increases, the object/group will move up (in increments). As the value of the expression decreases, the object/group will move down (in increments).
This property could be used to display the movement of an elevator.
Note: Vertical Movement cannot be used if the Vertical Slider is enabled. A group and its objects can be configured with any movement combination (i.e. a group can move vertically while one of its objects rotates, and so on).
Objects and groups have the following vertical movement properties:
Movement expression
The value of the expression entered in this field (253 characters maximum) will determine the vertical movement of the object/group. By default, when the expression returns its minimum value, the object/group will shift down to its lowest position. When the expression returns its maximum, the object/group will shift up to its highest position. For intermediate values, the object/group will move to the appropriate position between the minimum and maximum offset.
To insert a tag or a function, click the Wizard button to the right of this field. This button displays two options: Insert Tag and Insert Function.
[Movement expression] Specify range
Select this box to manually specify Minimum and Maximum values for the movement expression, rather than using the default values. For an expression containing an analog variable tag, the defaults are the Engineering Zero and Full Scale values from the last variable tag in the expression. If the analog variable tag does not have Engineering Zero and Full Scale values, the defaults are 0 (zero) and 32000. For expressions without tags, the defaults are 0 (zero) and 100.
[Movement expression] Minimum
Enter the minimum value for the expression. When this value is returned by the expression, the object/group will shift down, by the At minimum offset. You can only enter a value here if you have selected the Specify range box.
[Movement expression] Maximum
Enter the maximum value for the expression. When this value is returned by the expression, the object/group will shift up, by the At maximum offset. You can only enter a value here if you have selected the Specify range box.
[Offset] At maximum
The distance (number of pixels from the original object/group center) that the object/group will shift up when the Movement expression returns its maximum value.
You can change the offset value by pressing the up and down arrows to the right of the field, or by entering another value in this field.
[Offset] At minimum
The distance (number of pixels from the original object/group center) that the object/group will shift down when the Movement expression returns its minimum value.
You can change the offset value by pressing the up and down arrows to the right of the field, or by entering another value in this field.
Note: You can shift the object/group up at minimum and down at maximum, by entering negative distances in the Offset fields, or by swapping the expression limits (in the Minimum and Maximum fields).
