I -1. Introduction
Identification System is based on the
Kraftwerk - Kennzeichen - System (KKS)
This System is the basis for the standard and clear identification of all installations and subsystems
in power plant.
The present Part 1 is aimed to present the KKS general rules and it contains KKS keys for systems,
equipment units and components.
I - 1.1.
The origin and development of KKS
It is absolutely essential for the parties participating in the construction and operation of a power
plant to agree upon a standard system for the designation and classification of the plant, its part and
components.
Due to the size of power plants and the fact that the large number of parties participating are all in
different locations, communication problems arise which can incur costs which cannot be estimated
in advance.
A standard designation system enables each party, irrespective of language and assignment, to
identify uniformly and unambiguously, those parts of the plant within its responsibility. The Power
Station Designation System KKS satisfies these requirements to a degree not previously attainable.
The planning, construction and operation of power plants was based in the past on attempts to
identify installations and parts thereof by means of differing incompatible systems. The result was a
series of operations whose sequence was often irrational.
Bearing in mind the scale of power plants being built up to the early sixties, the Plant Identification
System AKS could be regarded as adequate for the needs of planning and construction engineers at
that time.
In the meantime, the AKS has been adopted as the main system of identification in a number of
conventional and nuclear plants.
Increased unit sizes, higher rates of automation and further developments in power-plant technology,
coupled with the demands made on classification systematics by power plant operators, all called for
a uniform and total solution of the classification problem.
A working party, consisting of planners, operating companies, authorized inspectors and other
authorities, was set up in 1970 with the task of finding such a solution.
The result of this joint effort is the Power Station Identification System KKS. This draws clear
divisions between power plant installations and systems, and takes full account of the needs of
manufacturers, operators, inspectors and other authorities as well as the technical requirements of the
mechanical engineering, process engineering, civil engineering, and electrical and control
engineering sectors.

Areas of application are:
• Planning and project engineering
• Licensing
• Erection
• Acceptance
• Commissioning
• Documentation
• Operation and supervision
• Maintenance
• Spares and replacement parts
• Defect statistics
• Plant accounts
• Plant budgeting and cost control
The Power Station Identification System: Kraftwerk - Kennzeichen - System (KKS) was
published in 1978 (1st edition) by the VGB and is now the basis for the designation of installations
and subsystems in power plants. Since this time the KKS has been further developed by the VGB
Technical Committee on Technical Classification Systems.
Current members of the technical committee are:
• ABB Asea Brown, Boveri AG
• Berliner Kraft- und Licht (BEWAG) AG
• Braunschweigische Kohlenbergwerke AG
• Energie - Versorgung Schwaben AG
• EPZ. The Netherlands
• ESKOM, Republic of South Africa
• F.D.B.R. Fachverband Dampfkessel, Behälter – und Rohrleitungsbau e.V.
• Gesellschaft für Reaktorsicherheit
• Hartmann & Braun AG
• Maschinenfabrik Augsburg – Nürnberg AG
• Rheinisch - Westfälisches Elektrizitätswerk AG
• Schnell - Brüter - Kernkraftwerkgesellschaft mbH
• Siemens AG, Corporate Groups E and KWU
• STEAG AG
• VDEN, The Netherlands
• VDMA, Verband Deutscher Maschinen – und Anlagenbau e.V.
• Vereinigte Elektrizitätswerke Westfalen AG
• Vereinigte Kesselwerke AG
KKS takes account of other relevant standards such as IEC, ISO, etc., and its principles are laid
down in DIN 40719, part 2.
I - 1.2.
Requirements to be met by the Identification System
To perform the set tasks the Identification system must be capable of satisfying the following
requirements:
• Determination of all installations and subsystems;
• An adequate number of reserve codes must be available for future developments in power
plant engineering;
Page
Identification System KKS
8/282
Part 1 – General
Chapter I – KKS Guidelines and Total Plant Key
• The classification of installations and subsystems must be generally applicable to all types
of power plant: all individual circuits and arrangements must, however, be clearly
identifiable;
• Clear identification of all subsystems;
• A designation used in a power plant must be nonrecurring;
• Subdivision with graded details and a fixed meaning for the data characters;
• Variable designation length depending upon the detail requirements of the various areas of
application;
• Independent designation of various systems must be possible;
• Ease of recognition ensured by clarity and an acceptable length for the designation;
• Plausibility check facility, especially for data processing;
• Account must be taken of existing standards, guidelines and recommendations.
I -2. Format of Code
I - 2.1.
Types of Code and Breakdown Levels
In consideration of the various requirements placed on the identification of plants, sections of plants
and items of equipment in power station, KKS has three different types of code:
• Process-related code
Process-related identification of systems and items of equipment according to their functions
in mechanical, civil, electrical and control and instrumentation engineering
• Point of installation code
Identification of point of installation of electrical and control and instrumentation equipment
in installation units (e.g. in cabinets, panels, consoles)
• Location code
Identification of locations in structures, on floors and in rooms and also of fire areas.
These types of code are distinguished by means of prefix and breakdown symbols.
These three types of code use the same identification scheme, which is subdivided into four
breakdown levels. Originally the titles of the breakdown levels were based on the process-related
code:
Serial no. of

Format of Breakdown Levels
The code is made up of breakdown levels. The individual breakdown levels are differently
formatted. They are made up of classifying and numbering code elements. The latter consist of data
characters occupied by alpha and numeric symbols.

In the middle line of the above table is written the designation of data character. The origin of the
letters used in it is in German language, namely:
G - Gesamtanlage: Total plant
(e.g. power station unit, non-unit-specific plant);
F - Funktion: Function
(e.g. main cooling water, piping system, steam turbine drain and vent system, generator
transformer incl. cooling system);
A - Aggregat: Equipment unit
(e.g. pump unit, valve incl. actuator, heat exchanger);
B - Betriebsmittel: Component.
(e.g. el. motor, coupling, protective device, delay device).
In Power Station Identification System KKS we apply two types of data character:
A - alpha characters (Roman letters except I and O)
Exceptional is the data character B1 where we apply for electrical components special
symbol “−” instead of a letter
N - numerical characters (Arabic numerals).

The breakdown levels and the data characters within the breakdown levels denote progressively
smaller entities from left to right. Read from left to right no data characters may be omitted. Special
guidelines apply to data characters G, F0 and A3.

The classifying coding letters and designations are established on a non-project-specific basis in the
KKS keys, namely as:
• Function key, for F1 F2 F3 on breakdown level 1 (see Chapter II).
• Equipment unit key, for A1 A2. on breakdown level 2 (see Chapter III)

The terminology of the key may be modified on a project-specific basis but only provided that the
contents are not altered. Such modifications are subject to agreement between the parties to the
project.
Coding letters which are “blocked” are reserved for future technologies and new systems
engineering configurations.
I - 2.3.2.

These numbering code elements are subject to agreement on a project-specific basis and between the
parties to the project as regards numbering systems and direction of numbering. However the
following principles apply:
•
•
•
•
Numbering starts anew when one of the preceding code elements changes.
Numbering may be consecutive or grouping.
Numbering need not be continuous.
Numbering conventions, once established, may not be altered, not even in the event of
changes made in the progress of planning.
• Redundant zeros must be written, except as modified below.
• An application-specific scheme of numbering may be established. However, such schemes
may not have the effect of reserving numbers in other applications, not even within the
same engineering discipline.

In classical KKS version, the so called “total plant” is designated in breakdown level 0 by one letter
or one digit (data character G).
The contents of this designation in KKS, is left for coordination for particular power plant. For
example we can identify here:
• power station units,
• non-unit-specific plants,
• extensions, etc.
Data character F0 contains so called prefix number. It is one digit which identifies one from two or
more identical subsystems in the overall plant. The prefix number is used in cases when for instance
in compass of one power unit appear two or more identical subsystems (two boiler plants, two
turbosets, etc.). Adoption of a.m. data character is remained in KKS also for coordination for given
power plant.
Data character G as well as data character F0 can be omitted in KKS if the further part of designation
will remain complete univocal.

• System numbering
It is numbering subdivision of systems and plants into subsystems and sections of plants.
Numbering starts anew when one of the preceding code elements changes.
System numbering must consist of two digits. Redundant zeros must be written e.g. the fourth
section of a system which is classified with letters LAE will be designated LAE04.
Generally valid rules on the use of FN numbering are not expedient. It should be decided on a caseto-case basis which numbering convention is best suited to the extend and structure of the systems
and plants to be identified.
FN numbering is governed by the following principles:
• Numbering starts anew when one of the preceding code elements changes;
• Numbering may be consecutive or grouping;
• Numbering need not be continuous;
• Numbering conventions, once established, may not be altered, not even in the event of
changes made in the progress of planning;
• The direction of numbering coincides as a rule with that of fluid flow;
• FN numbering is governed by priorities (e.g. run pipe and branch pipe) or by a defined
direction of view (e.g. from left to right, from bottom to top);
• The possibility of later addition to the systems should be considered in the course of
numbering.

Examples
Examples of the identification of installation spaces in panels
To identify the installation space, draw on front of the panel coordinate system origin
- so called grid. Subdivide for this aim the panel elevation into planes:
• horizontal (x axis)- the result of subdivision are lines (rows),
• vertical (y axis)- the result of subdivision are columns (spaces).
Such established grid after addressing can state the coordinate system.
The coordinate system made by construction (so called „constant grid”) appears in panels of
electronics, control rooms etc.
Examples:
X - axis
columns
Y- axis (lines)
front of the panel (service side)

The code may be written with or without spacing but in such a way that it cannot be misinterpreted.
The allowable notations are fixed. Their use for any intended purpose is subject to agreement
between the parties to the project.
Spaced notation promotes the comprehensibility and mnemonic quality of codes. Codes may be
spaced by the insertion of blank spaces or interposing lines at predetermined points and by multipleline notation:
“small spacing” Blank spaces or interposing lines between the breakdown levels for codes which
do not have to be understood within a limited period of time;
“large spacing” Blank spaces or interposing lines between alpha and numeric elements within the
breakdown levels where the breakdown levels are more than 4 data characters long, for example for
codes in the control room, which have to be understood in a relatively short period of time.

Assignment of System Codes to Mechanical Equipment and
Measuring Circuits
Equipment units are identified according to the system within the interfaces of which they are
located. Supply systems which serve only one equipment unit are identified on an equal footing as
subsystems of the system in which they are installed. Where an equipment unit serves as an interface
between two or more systems, its system code is assigned on the originator principle, i.e. according
to the system whose functions require the items concerned. Measuring circuits are identified
according to the system within the interfaces of which the sensor is installed.
I - 5.3.
Special Rules for Mechanical Engineering
I - 5.3.1.
Valves
Valves are identified on the equipment unit level by the letters AA regardless of their type, design or
actuator. Safety equipment, consisting of safety valves and their associated piping, are assigned to
the system to which they are connected.
Drains and vents are identified as far as the final isolation element – including double valves – or as
far as the open outlet as part of the drained or vented system (originator principle). This applies
analogously to supply systems.
System isolation valves for measuring circuits are identified on the level of the equipment unit code
by the classifying letters AA. Subsequent isolation and pressure equalization valves in the measuring
circuit are components of the measuring circuit and therefore classified as KA.
I - 5.3.2.
Mechanical Supports
Supports may be identified using the system code or the structure code. On breakdown level 2
supports should be identified by BQ.
Structure-related identification is expedient where different systems are held by shared supports.
System-related identification is expedient where the supported items are positively assignable to one
system.

Special Rules for Electrical and Control and Instrumentation
Engineering
I - 5.5.1.
Shared equipment
Combined electrical and control and instrumentation equipment
Combined electrical and control and instrumentation equipment, with or without a power unit (e.g.
housed in one cabinets), is identified on breakdown level 1 under letters CM to CT (subdivision for
system combinations) or D. If necessary, further grouping can be performed by using FN.
Transducer Racks, Supports, Frames
This auxiliary equipment is identified on breakdown level 1 using the code for the equipment
location (structure code), with the exception of auxiliaries for main machine sets and heavy
machinery (system code). On breakdown level 2, transducer racks, supports and frames are identified
by means of GZ.
Junction Boxes
On breakdown level 1, junction boxes receive the code of the structure and floor on which they are
installed. Exceptions are junction boxes for main machine sets and heavy machinery, and junction
boxes in electrical and control and instrumentation cubicles and cabinets; these are identified on
breakdown level 1 according to the associated main machine or heavy machine and cubicle or
cabinet respectively. On breakdown level 2 junction boxes are identified by means of A1 = G
(electrical equipment).
Connections
Connections are identified in accordance with DIN 40719 Part 2 by means of a dedicated code unit
which is preceded by the prefix symbol “ : ” (colon). This code unit can be combined with any
breakdown level as necessary for identification. Any combination of alpha and numerical symbols
appropriate to the requirements is acceptable for the identification of connections.
I - 5.5.2.
Electrical Equipment
Transformer Systems for Power Transmission and Auxiliary Power Supply
Transformers are identified on breakdown level 1. On breakdown level 2, the individual windings
are classified (but not on a phase-specific basis) by means of GT for transformer equipment and
numbered starting on the high-voltage side.
Measuring Transformers
The types of measuring transformers as well as their quantities in the given system are identified in
breakdown level 2 by letters GT and three digits. Particular cores and phases of measuring
transformers are identified in breakdown level 3 by component symbols “ –T ” and by two digits.

Switch gear, Battery Chargers, Inverters and Battery Sets
These systems and items of equipment are identified regardless of equipment location in the
classifying section of breakdown level 1 in accordance with the rules for main group F1 = B. If the
letters available are insufficient, FN may be used. In such instances the first character of FN has a
classifying purpose. The second character of FN numbers the cubicles.
I - 5.5.3.
Control and Instrumentation Equipment
I - 5.5.3.1.
Measuring Circuits
Measuring circuits comprise analog signal acquisition, conditioning, distribution and measured data
recording and indicating processing elements. They are generally identified after the system within
the interfaces of which the sensor is installed.
On breakdown level 2, direct measuring circuits are identified by means of A1 = C, indirect
measuring circuits (gated or calculated) by means of A1 = F and A2 according to the measured
physical variable (e.g. pressure, temperature).
Equipment Unit-Specific Analog Signal Processing and Measuring Circuits
Equipment unit-specific analog signal processing elements comprise control and instrumentation
equipment which is only provided for one equipment unit such as control interface, protective logics,
instruments in the feeder and command termination for final control elements. These analog signal
processing elements receive the code of the equipment unit concerned.
Function-Specific Analog Signal Processing
Function-specific analog signal processing elements comprise gates between more than one
measuring circuit and / or equipment unit-specific analog signal processing elements for systems
such as open-loop control (but not control interfaces). They encompass the control and
instrumentation equipment for more than one equipment unit and are identified on breakdown level 2
by means of A1 = E (analog and binary signal conditioning). A2 identifies control and
instrumentation functions (e.g. alarm gating, subgroup control).
Function-Interfacing Analog Signal Processing
Where control and instrumentation equipment serves more than one process system identified in F2
and F3, the letter Y for generic control and protection systems may be used in the appropriate data
character on breakdown level 1. Control and instrumentation equipment which serves more than one
main group may be identified under main group C for control and instrumentation, e.g. unit control
system = CJA.

Given the possibilities shown in the table, it is not practicable to meet all possible requirements for
identification of discrete process-related function (e.g. functional group control). Thus for example,
it may be necessary to use items which are identified differently on breakdown level 1 (main system
and associated parts of auxiliary and ancillary systems) in order to fulfil a given process-related task
(functional group). Identification of the functional groups involved in process-related tasks so as to
relate them to the principal task concerned may be performed by using the alpha characters in F1...F3
of the principal process-related task.
In this application, however, a suitable identifier such as a prefixed Y should be used to indicate that
a software coding unit is concerned, thus to rule out confusion with process-related codes. This code
is subject to agreement between the parties to the project.

Analog Signal Gating
In principle, it is true of signal linking functions that the code of the signal to be processed is retained
after the gating element, e.g. for alarm gating.
Gated analog signals representing physically similar direct measured variables are identified by
means of a set number, e.g. “9”, in the first data character of AN and retain the code of the physical
variable in data character A2.
Gated analog signals representing physically dissimilar indirect measured variables are identified by
means of A2 = U (combined variables) provided the output variable is dimensionless.
Where signals or measured data are used to limit or suppress the original measured data, the
processed output signals retain the code of the original measured data.
Where measured data are corrected (e.g. flow measurement corrected for pressure and temperature)
and if only the corrected measured data are further processed, the codes stay the same as those of the
origin measured data in spite of the gating of dissimilar measured data.
Where a distinction is to be made between calculated analog data after analog data gating functions
and the original measured data, the indirect (calculated) measured variables are identified by means
of A1 = F (indirect measuring circuits). Identification in data character A2 is governed by the
physical variable.
I - 5.5.3.2.
Closed-Loop Control Circuits
The principles for the identification of measuring circuits apply analogously to the identification of
closed-loop control circuits on breakdown level 1. Every control loop and every closed-loop control
circuit comprises measuring, control and positioning elements regardless of whether electrical,
pneumatic, hydraulic or other items of equipment are used. Closed-loop controls are identified
according to the controlles variable and not after the measuring circuits which serves the control or
the final control element on which the control acts.
I - 5.5.3.3.
Signals and Signal Applications
Breakdown level 3 is used to identify signals and their applications. For this purpose, data character
B1 can contain:
X
Signal origins
Y
Signal applications
Z
Gated signals
No generally valid rules have been made for signal and application areas. They should be established
individually for different control and instrumentation concepts.

The alphabetical symbols of this breakdown level are used to classify and divide the overall plant
into subsystems, systems or building structures.
24 Roman letters except I and O are used as alphabetical symbols. It is not allowed to use any other
letters.
Wherever possible, all three alphabetical symbols are permanently allocated, including their
associated boundary constraints and task allotment in modern power plant technology.
Coding letters of the main groups F1 are specified on next and the subdivisions in F2 and F3 are given
in the present chapter II.
The numerical digits count and subdivide the unit (e.g. sections of piping system, cubicles, floors of
buildings etc.) coded in the last alphabetical symbol.
New KKS symbols are mostly marked on Process and Instrument diagrams.
Usually the code is written above the line:
09LBA11
or the “flag” symbol represents codes for piping. The flag points in the direction of fluid flow.
System
One should remember, that the code of a system must consist of five symbols: three letters and two
numerical symbols. No one of these symbols can be omitted.

III - 1.1. Equipment Unit Identification
In the process-related code which is the most important and mostly applied type of codes in every
branch of engineering, the entire system is subdivided according to the function or process.
In this type of code, the breakdown level 2 contains equipment unit code.
Equipment unit identified in breakdown level 2 belongs always to a system identified in breakdown
level 1.
Equipment unit code consists of 2 letters (data characters A1 and A2), 3 digits (data characters AN)
and sometimes 1 letter (data character A3) which can be, and often is omitted.

Numbering code elements
The AN number of breakdown level 2 is used to number the items of equipment classified in A1 and
A2.
Redundant zeros must be written, e.g. CF012 means the twelfth local measuring circuit of fluid flow
(the code CF12 is not correct).
The numbering code for the main group “C” (direct measuring circuits) in the same system and for
the same measured variable should not repeat in the last two numerals, although it is distinguished
by the first numeral.
Details of equipment unit numbering are subject to agreement between the parties to the project.
It is a common practice to apply a grouping numbering of equipment units: the first numeral points
the kind (type) of equipment unit identified in A1 and A2 (e.g. AA1 . . manual operated valves,
AA2 . . motor operated valves, etc.)

Additional code
For the equipment unit code.
The additional code is used for the numbering of:
• Pilot valves and overpressure protection equipment
• Multiple supplies for electric loads
• Measuring circuits which share one sensor.
The additional code can be omitted.
Further applications are subject to agreement between the parties to the project.
The additional code is not an alternative code for the components identified under breakdown
level 3.

In digital systems , in which automatic regulation systems are most often realised with
standard procedures, other ways of describing of regulation systems are applied. Modern methods of
digital systems programming and ability of efficient use of technical documentation require to use
the concept of functional group ( positions A1 and A2 ) and number of the group ( positions An - three
numerals) depending on degree of complexity of automatic analog control system.
In case of single automatic regulation circuits there is possibility of using rule of identifying
this circuit with so called „object end”, that is executive device. All signals in such automatic
regulation system in breakdown level KKS 0, 1, 2, are described identically. These signals differs
only with component code so called ‘extensions’. This rule does not refer to direct measurement
circuits, which apply to technical installation and physical variable. The way of assigning
‘extensions’ is described in chapter IV - Component codes.
In case of single closed regulation circuits, it is divided into 2 parts: regulation part and
control part. Regulation part is described in level 1 by process-related installation, and level 2 by the
controlled parameter - control part is described by executive device e.g.
H1 LAD10 DL100
H1 LCH10 AA201
regulation part - level loop in HP heater no. 3
control part - level loop in HP heater no. 3
Referring to combined (superior) automatic regulation systems for sign position AN (three
numerals) it is recommended to apply the following rules :
• 100, 200, 300 etc. - the whole main circuit e.g. boiler load analog control loop
• 101, 102, 103 etc. - auxiliary circuits in main circuit
Manual regulation circuits ( URR ) are described on levels 1 and 2 according to the same
way, while AN numbers are between range 001 and 099.

Referring to conditioned variables ( E ) for code position AN ( three numerals ) it is recommended to
apply the following rules:
• 100, 200, 300, etc. - whole main circuit related to signal conditioning e.g. control
• 101, 102, 103, etc. - auxiliary circuits of signal conditioning in main circuit
The numbers of functional group (code positions AN - three numerals ) are very often indicated by
other conditions which help quickly to locate this group , e.g.
• in one or two channels systems ( Simatic system ) each protection algorithm is given
identical functional group’s KKS and number of function is conform to address of
software program block „FB”
for “FB10”
10HYH10EY10n
•
for “FB45”
10HYH10EY45n
for “FB12”
10HYH10EY12n
„n” means the consecutive number of algorithm, if there is more than
one in a block.
in three channels systems (system Procontrol P13 ) each algorithm is given the same KKS
of functional groups (numbers of functions), functional groups are distinquished by
consecutive numbers related to channel number for the same function, e.g.
10HYH10EY101
channel 1
10HYH20EY101
channel 2
10HYH30EY101

In Teleperm system each analog signal conditioning group is given KKS number
according to cubicle (in level 1) while function number is the same as number of position
of the card in this system ( so called „Steckplatz” ), eg.

cubicle no.1 , “steckplatz” no. 25
10CJJ01EM121

Creating combined (secondary) variables
Refering to indirect measuring circuits, realized in Digital Control System (DCS), there are
rules that only in case of mathematical-logical operations letter „C” to „F’ is being changed , with
modification of serial number at the same time , depending on processed operation . On the contrary
in case of mathematical-logical operations created on field equipment , measurement circuit changes
only its serial number at the position describing kind of electrical variable to „9”. The next counting
signs of the circuit does not change when is creating only one combined variable. In case for eg. one
combined variable:
• CP201
direct measurement of pressure
• CP202
direct measurement of pressure
combined variable:
• CP901
calculated difference of pressures
e.g. for few combined variables:
• CP201
direct measurement of pressure
• CP202
direct measurement of pressure
combined variables:
• CP901
calculated difference of pressures
• CP902
calculated extremum
Secondary variables created in digital systems DCS for the same installation (circuit)
Secondary variables created from one specified measuring variable get number of direct
measurement of this variable. E.g. after selection 1 of 2 : change „C” to „F”, but number remain
without change e.g.
• direct measurement of temperature
CT301
•
direct measurement of temperature
CT302
•
selection 1 of 2 measured temperature
FT301
Secondary variables calculated as a result of a few measuring variables of the same kind as a sum,
difference, extreme result, average. For example maximum of a few direct measured variables:
change “C” to “F”, number begin from 900 and the end according to measured variable e.g.:
•
direct measurements of temperature
CT301, CT302, CT309, CT310
•
maximum value of these temperatures
FT901
E.g. : after selection 2 of 3: change “C” to “F” is making, number is similar but beginning from 900
•
direct measurement of temperature
CT301, CT302, CT303
•
selection 2 of 3
FT901
Page
Identification System KKS
204/282
Part 1 – General
Chapter III – Equipment Unit Key
In case of calculation a few secondary variables from the same circuit (installation) it is nessesary
not to repeat the identical numeration for different variables but to do it consecutively. E.g. average
number , selection 2 of 3, minimum : change “C” to “F” , numbers consecutive but beginning with
900:
•
direct measurements of pressure
CT301, CT302, CT303
•
average value of these temperatures
FT901
•
selection 2 of 3
FT902
•
minimum value of these temperatures
FT903
Secondary variables calculated as a result of a few measuring variables of different kinds gets
numbers beginning with 900 and the ends according to measured variables, with changing the
second letter of the code to “U”. E.g., calculation of the enthalpy:
•
direct measurement of pressure
CP202
•
direct measurement of temperature
CT301
•
calculated enthalpy
FU901 or FU902
When creating redundancy indirect measurement circuits ( eg. when creating the double signals of
limits for instrumentation and control systems 1 of 2) it is necessary to follow the rules:
double circuit gets symbol like a basic circuit with change of the numbers 200, 300, 400 to 600 and
900 to 700. For example:
•
indirect measurement of pressure
FP201 ⇒ FP601
•
indirect measurement of temperature
FT301 ⇒ FT601
•
indirect measurement of saturation temp.
FT901 ⇒ FT701
Secondary variables created in digital systems (DCS) of the same installation where
differs only with counting sign.
When creating in DCS systems secondary variables of the same technical installation that differs
with counting sign for breakdown level 2, the same rules are to apply as for this variables created
from the same installation. But it is necessary to modificate the counting signs of breakdown level 1
- installation unit code.
When technical installations differs only with counting signs of installation it is necessary to assign
to a secondary variable counting signs like for one of those installations e.g.
•
direct measurement of pressure
LAA10CP201
•
direct measurement of pressure
LAA20CP201
•
average measurement of pressure
LAA10FP901

or counting signs “passive” (neutral), that is not appeared in identification code of these installations
e.g., “00”
•
direct measurement of level
LAA30 CL201
•
direct measurement of level
LAA40 CL201
•
average measurement of level
LAA00 FL901
Secondary variables created in DCS systems from different technical installations
In case of creating secondary variables in DCS systems from different technical installations, to
describe technical installation is used rule which appears in chapter II , while device component is
described by rule appeared above, e.g.
• direct measurement of pressure
LBB21 CP201
•
direct measurement of pressure
LBC11 CP201
•
