Options on the Horizontal Position tab

Specify a tag name or an expression that will evaluate to numeric values at runtime. An expression is a mathematical or logical equation that returns a value. It can contain tag names; constants; mathematical, relational, logical and bitwise operators; and built-in alarms and events functions. A tag name can be used as an expression.

If you have specified a tag in the Expression box, click this button to use the tag's minimum and maximum values to define the range of values for the expression. This option only applies to tags for which minimum and maximum can be defined, such as HMI tags.

To use constant numeric values to define a range of values, click this button and specify values for minimum and maximum.

To define the range of values using one tag's value for the minimum and another tag's value for the maximum, click this button and then specify a tag for minimum and another for maximum. Using this option, when the animation for an object is started, the tags' values are read once to set the minimum and maximum values. The tags are not read again after, nor are the minimum and maximum values changed.

Horizontal offset determines the object's position in the display. The At Minimum and At Maximum fields determine where the object is to be at the expression's minimum and maximum values.

Specify the starting position of the object in pixels, or drag the object to its starting position then click the check box. The offset value, in pixels, will reflect the object's new position.

Specify the ending position of the object, in pixels, or drag the object from its start to its finish position, then click the check box. The offset value, in pixels, will reflect the object's new position.
