The following procedure explains how to create an association between a reference control station or reference instrument and a reference equipment item. For example, you can create an association between a reference motor and a reference control station or create an association between a reference instrument and a reference heater.
After an association has been established, the software places a logical connector between the two associated items. By default, the software shows logical connectors as black dashed lines. You can change the style of the line by using the Define Item Type Symbology feature in Options Manager (in Options Manager, select .Options > Item Type Symbology > Define).
The association created by the software is only kept in the typical CBD drawing that you are currently working on. After creating a plant CBD based on the current typical CBD, logical associations will become real associations between plant items.

Open an existing typical CBD or create a new one.

Select one of the required items and then the other item to associate them with each other.
The software places a logical connector between the associated items. The logical connector is shown as a black dashed line.
To dissociate two items from each other, do one of the following:
-
Select the required logical connector and then press the Delete key or select (Remove) on the Edit drawing toolbar.
-
Remove one of the associated items from the drawing.
