On the Graphics tab, in the Animations group, click Color to add the animation to a selected object. The Colors animation allows you to modify the color of a static object during runtime based on the value of a tag or expression.
Double-click on the object to open the Object Properties dialog.
Figure 1. Object
Properties: Colors
You can use this dialog to specify the following
parameters:
- Type: Determines
the mode in which this animation works:
- By Limit: When selecting this type, you can specify up to four limits (Change Limit) for this animation and a color for each limit. When the value of the tag or expression configured in the Tag/Expr field reaches the limits, the color associated with the respective limit is applied to the object.
- By Color: When selecting this type, you can specify the code of the color that must be applied to the object directly in the Tag/Expr field. Using this code, you can apply any color supported by your device to the object.
Tip: You can configure the RGBColor function in the Tag/Expr field when Type = By Color. This allows you to configure the color by its RGB codes. See Color Interface for a table with the codes for the most commonly used colors. - Tag/Expression field: Type the name of a tag or expression you want to monitor. When Type = By Limit, IWS compares the result of the tag/expression with the specified Change Limits to determine the proper color for the selected object. When Type = By Color, the result of this field sets the color that will be applied to the object.
- Change Limit
field: Type a limit value (a numeric constant or tag) for the color
change. The numbers must be configured in ascendant order according
to the following sequence of the fields displayed on the Object
Properties dialog: Upper left, lower left, upper right and lower
right field. If you click on the More button, you can configure up
to 16 different limits for the color animation.

Note: The
following fields are automatically disabled (grayed out) when
