For sp cif i ation purp ses, this stan ard u es the tec niq e of o ject model n

An o ject is a col ection of atributes an method At ributes re resent the c aracteristic of

an o ject The value of an at ribute may af fect the b haviour of an o ject The f irst at ribute of

an o ject is the logic l_ ame It is one p rt of the identifi ation of the o ject An o ject may

of f er a n mb r of method to either examine or modif y the values of the atributes

Objects that s are common c aracteristic are generalzed as an interface clas , identified

with a clas _id Within a sp cif i IC, the common c aracteristic (at ributes an method ) are

des rib d on e for al o jects In tantiation of ICs are cal ed COSEM interf ace o jects

Man facturers may ad pro rietary method an at ributes to an o ject; se 4.2

Fig re 2 i u trates these terms by me n of an example:

R egist er cla s_id

The IC “Register” is f ormed by combinin the features neces ary to model the b haviour of a

generic register (containin me s red or static information) as se n f rom the clent (data

col ection s stem, han held terminal) The contents of the register are identif ied by the

at ribute lo ical_ ame The logic l_n me contain an OBIS identif ier (se IEC 6 0

6-6-1:2 15) The actual (d namic) content of the register is car ied by its v lue at ribute

Def i in a sp cif i meter me n def i in several sp cif i o jects In the example of Fig re 2,

the meter contain two registers; i.e two sp cif i in tan es of the IC “Register” are

in tantiated Throu h the in tantiation, one COSEM o ject b comes a “ otal, p sitive, active

energ register” where s the other b comes a “ otal, p sitive, re ctive energ register”

4.2 Ref ere cing methods

Atributes an method of COSEM o jects can b ref eren ed in two dif ferent way :

Using logic l name (LN referencing): In this case, the at ributes an method are

ref eren ed via the identifier of the COSEM o ject in tan e to whic they b lon

The referen e f or an atribute is: clas _id, value of the logic l_n me at ribute,

at ribute_in ex

The ref eren e f or a method is: clas _id, value of the logic l_ ame atribute, method_in ex,

where:

• atribute_in ex is u ed as the identif ier of the at ribute req ired At ribute in exes are

sp cif ied in the def i ition of e c IC They are p sitive n mb rs startin with 1

Pro rietary at ributes may b ad ed: these s al b identif ied with negative n mb rs;

• method_in ex is u ed as the identif ier of the method req ired Method in exes are

sp cif ied in the def i ition of e c IC They are p sitive n mb rs startin with 1

Pro rietary method may b ad ed: these s al b identified with negative n mb rs

Using short name (SN referencing): This kin of ref eren in is inten ed for u e in simple

devices In this case, e c at ribute an method of a COSEM o ject is identif ied with a 13-bit

integer The s ntax f or the s ort name is the same as the s ntax of the name of a DLMS

named varia le Se IEC 613 4-4-41:19 6 an IEC 6 0 6-5-3:2 16, Clau e 8
