When creating or editing the properties of a wiring item, Smart Instrumentation validates that the wiring item has a unique name and sequence. The software applies the following validation rules:
Item Sequence
If Smart Instrumentation detects that the sequence of a wiring item is not unique, the software displays an appropriate message and does not create the item until you enter a unique sequence.
The software validates sequence uniqueness according to the following rules:
-
In an owner operator domain, the software validates sequence uniqueness in As-Built and all the projects belonging to the current owner operator domain.
-
Panels, cables, and connectors do not require any sequence.
-
Terminals must have a sequence which is unique at the terminal strip level.
-
All the other wiring items must have a sequence which is unique at the level of the immediate parent item under which the item exists.
Item Names
If Smart Instrumentation detects that an item does not have a unique name, the software displays a warning message, after which you proceed depending on the setting you made on the General page of the wiring preferences. You can set the software to proceed without changing the item name if you do not select the Enforce name uniqueness wiring preference option on the General page. If you select the Enforce name uniqueness check box, you must rename the item to proceed with your work.
The software validates name uniqueness according to the following rules:
-
In an owner operator domain, the software validates name uniqueness in As-Built and all the projects belonging to the current owner operator domain.
-
For panels and cables, Smart Instrumentation checks for name uniqueness at the level of the current <plant>.
-
Wires do not require name uniqueness.
-
The software checks for terminal name uniqueness at the terminal strip level.
-
For all the other wiring items, Smart Instrumentation checks for name uniqueness at the level of the immediate parent item under which the item exists.
-
If you try to create a wiring item that has no name, the software prompts you to enter a name. If you select the Enforce name uniqueness wiring preference option, the software treats items without names according to the validation rules stated above. If you do not select this wiring preference option, the software allows you to create wiring items without names.
-
When moving an item to another parent item, the software validates the name uniqueness at the target level. If you did not select the Enforce name uniqueness wiring preference option, the software moves the item and retains its name. If you selected the Enforce name uniqueness wiring preference option, the software does not allow you to move the item if the item name violates the validation rules.
