The object parameter is a link between commodity codes and geometric tables. The geometric tables hold all the dimensions that are needed to create the size-dependent description of a component.
The object parameter is a grouping and arrangement of geometric attributes. The purpose of the object parameter is to achieve a common depth of description of objects. Object parameters must be defined so that they cover a meaningful number of similar objects (for example, pipes, bends B2, B3, B5, screws, and so forth). The number and description depth must be large enough to be sufficient for the envisioned usage. Object parameters supplement the commodity codes to produce a meaningful whole.
The object parameters are defined on the S.10.04 Object Parameter screen, and the object parameter details on the S.10.05 Object Parameter Details screen. To clearly describe the 90 degree elbow for our example, we need an object parameter with one nominal pipe size (NPS) and one schedule (SCH), as defined in the geometric table that will be used to build the idents. See the picture below.
The existing object parameter P_1N1S_E contains exactly these two attributes.
All geometric attributes needed to describe the component and to build the idents must be included in the object parameter details. With the object parameter details, you define the name of the attributes, whereas the exact attribute name used in the geometric table must be entered in the Attr Name field, and the same name or any synonym can be entered in the Name field. The Input? check box indicates if it’s an input or output value. With the Ident? check box you define if this attribute is needed for ident creation, to make the ident unique. For optional attributes the Opt? check box is selected. The attribute unit is copied from the attribute definition on A.50.01 Attributes to the Unit field. The Kind of Detail field indicates the type of the attribute, and the available values in the drop-down list are:
-
1./2. Nominal Size
-
1./2. Schedule
-
Nominal Pressure
-
Size Range From/To
-
Bolt Diameter/Length
-
Other
Use the Short Desc and Description fields to enter meaningful information.
Click the Next Block button to open Window 2, where you can define the layouts for the object parameter. When the idents are built, this layout will be concatenated with the commodity code layout to build the ident layout.
Use the list of values to select the necessary text modules. The attributes assigned to the object parameter in window 1 are available. These values are entered enclosed with # characters. Key in any fixed text strings when needed. To create tabulated text, use the CTRL + TAB keys from the keyboard.
All object parameters that might be used to build idents for a commodity code must be assigned to the part that is associated to the commodity code on S.10.06 Part Object Parameter.
Now the object parameter can be assigned to the commodity code as described above.
