You must initialize a KKS domain using a KKS database. Smart Instrumentation supplies an empty KKS database (IN_KKS.ddti found in the folder where you installed
Smart Instrumentation. In addition, you must select the KKS mode check box in the Domain Definition window.
For the KKS naming convention to function the Rule Manager option must be selected in the Domain Definitions. You then, in Rule Manager using the KKS Cable Name rule, set the number of segments to be used in the calculation of the unique suffix number in the KKS name.
Smart Instrumentation supports KKS naming conventions for process-related identification of the following item types:
-
Instruments (including functional requirement tags and virtual tags)
-
Loops
-
Lines
-
Process equipment
-
Control system tags
-
Panels (plant panels only, belonging to panel categories available in the Convention list in the Naming Conventions dialog box)
-
Cables (plant cables only)
For each of these item types, the following KKS segment properties are available:
|
KKS Level Name |
Property |
Description |
|---|---|---|
|
Total Plant |
Total Plant |
Single character (numeric or alphabetic). |
|
System Code |
System Code Prefix (optional) |
Single digit. |
|
System Classification |
Three-character alphabetic key, selected from a standard list, that represents the type of system in use the plant. |
|
|
System Numbering |
Two-digit number with leading zeros. |
|
|
Equipment Unit Code |
Equipment Unit Classification |
Two-character alphabetic key, selected from a standard list that represents the type of equipment within the system used for measuring or monitoring the system, or the type of measurement circuit (level, flow, and so forth). |
|
Equipment Unit Numbering |
Three-digit number with leading zeros. |
|
|
Equipment Unit Additional Code |
Optional character (alphabetic). |
|
|
Component Code |
Component Classification |
Two-character alphabetic key, selected from a standard list that represents the type of component. |
|
Component Numbering |
Two-digit number with leading zeros. |
|
|
Numbering Element (for cables only) |
Application Area |
Single digit (0-9) representing the application area of a cable (voltage levels). |
|
Cable Number (digits 2 and 3) |
Two-digit number. |
|
|
Cable Suffix |
The fourth position of the cable number, a numeric character, mostly used for grouping purposes. |
-
Smart Instrumentation does not auto-increment the numbering of the various segments in the process identification.
-
The software does not automatically add leading zeros to imported items whose names include spaces. You must manually add the leading zeros to the source before importing KKS data.
Process Identification Prefix and Notation Characters
Process Identification usually uses the equal (=) character as a prefix. Identification may include space (" ") or pipe (|) characters.
Examples
For a medium voltage panel (excluding device panels), only the System Code segments are required in most cases. Thus, a suitable KKS name would be 1 0BBA01, where the values are designated as follows:
|
Property |
Value |
Description |
|---|---|---|
|
Total Plant |
1 |
|
|
System Code Prefix |
0 |
|
|
System Classification |
BBA |

|

For a flow transmitter, the KKS identification 1 0PAE01 CF013 –B01 could be used, where the values are designated as follows:
|

-
When creating a new instrument, the associated loop inherits the relevant segments of the instrument names and vice versa. Also, KKS naming is propagated to cables when you connect them to panels that already have KKS naming. Cables inherit the KKS naming of the panel whose system code is first in alphabetic order.
-
Not all items use all the described segments. For example, DCS and PLC panels do not use equipment unit code and component code segments. Marshaling racks, junction boxes, process equipment, and lines do not use component code segments.
-
When editing a name using the KKS naming conventions, do not remove any segments from the name. Removing segments from the KKS name causes problems when creating new instruments. You can though add more segments to the KKS name created in Smart Instrumentation.
-
You can change the terminology of a key on a project-specific basis provided that the contents remain unchanged. Make sure that you do not select a code that is designated as Blocked. Blocked coding letters are reserved for future technologies and new systems engineering configurations. They may only be allocated and released by the VGB Technical Committee on Technical Classification Systems.
