4.3 Dynamics
Dynamics are specifications for changes in graphic objects. These changes can be in response to changes
in variables such as atoms in a controller. For example, when a controller atom changes state or value, this
can be translated into a graphical change in a screen object, such as a change in color of a filled rectangle.
Dynamics can also specify non-graphic actions, to be performed in response to user actions, such as vec-
toring to a different display or changing the setpoint of a Control Module.
Dynamics can be configured by several methods, all of which are accessed from the pop-up menu avail-
able via the right mouse button. To access this menu, position the pointer over the object for which
dynamic attributes are to be configured, then click the right mouse button. The following options are used
in configuring dynamic attributes.
1. Configure Submodel. Dynamics defined in a submodel can be configured (customized) for an
instance of that submodel, via the CONFIGURE SUBMODEL item.
2. Dynamic Attributes. Dynamics which affect a limited set of graphic attributes of an object or
submodel, based on the value of a user-defined expression, can be configured through the
Dynamic Attributes item.
3. Custom Dynamics. Custom dynamics can be created, using the GML language, via the
Custom Dynamics menu item.
4.3.1 Configuring Dynamic Attributes for Objects
To configure dynamic attributes for an object (including submodels), the object must exist in the Working
View. Position the pointer over the object and click the right mouse button. Select the Dynamic Attributes
item on the resulting pop-up menu. The Expression Dynamics window (
Figure 4-11 ) will be displayed.
The Expression entry box on the Expression Dynamics window allows you to enter mathematical opera-
tors, parentheses, variables and data values in a syntax like that of the C programming language, to create
✎ Note
The Expression Dynamics window can also be displayed by
selecting the Grafx menu sequence Edit > Object > Dynamic
Attributes.
