2. Data Items

Overview: Data item Configuration

A data item is a definition that becomes a CIMPLICITY point when an object is created from the class.

A data item:

• Can be used in any application that supports points, for example:
• Database Logger
• Event Editor
• BCE
• Point Control Panel
• CimView
• Other CIMPLICITY Software Options
• Can include a subset of expressions of type: string or numeric. Note that a limited number of string substitutions and numeric expressions are supported.
• Displays in the Workbench right pane as a point with its associated object.

Overview: Data Item Instantiated into a Point

Data items are instantiated into CIMPLICITY points, as follows.

1. Class: Data Item Configuration

Data items are configured in Data Item dialog boxes that are opened through the Class dialog box.

Example

An analog data item named LEVEL is created.

Note: Data item ID's are listed on the Data Items tab in the Class dialog box.

1. Object: Object Created

A class is selected to create an object.

Example

A class object created from the class TANKS is named: STATION01.

1. Instantiation: Data Item to Point

Data items are instantiated into points for the new object.

Workbench

The instantiated points are listed in the Workbench right pane.

Example

STATION01 instantiated points are listed in the Workbench.

The data item LEVEL instantiated into a class object point is named: STATION01.LEVEL.

Point Properties Dialog Box

An object's Point Properties dialog box can include several ??fields that class/object configuration have caused to be read-only.

Example

Several data items have been entered in the LEVEL Data Item dialog box.

Those fields in the STATION01.LEVEL Point Properties dialog box are read-only.
