GPS-X Objects
WHAT IS AN OBJECT
An Object refers to the icon, which appears on the GPS-X Drawing Board when selected from
the Process Table. An object is a symbolic representation of a unit process without any process
model associated. There are several items associated with the object:
1. The hydraulic configuration;
2. Physical attributes;
3. Operational attributes;
4. Display Variables;
5. Stream labels; and,
6. Sources.
The hydraulic configuration refers to the number of connection points on an object and the
operation of these connection points; that is, whether the connection point is incoming or
outgoing. The parameters and stream labels are under the Parameters sub-menu and Labels...
sub-menu respectively. Additional sub-menu items are found under the Parameters menu, which
are process model and library specific. The Display Variables menu item is used to select model
variables for display on a graph, while the Sources menu item displays the object number that
acts as a source for some of the Parameters.
Not all menus are active. For example, until the model is chosen for an object, the Parameters
and Initialization menus (if they exist for the object) are not active and appear greyed out. Once
the model has been specified, these menus will become active.
