IEC 62056 6 1 Edition 2 0 201 5 1 1 INTERNATIONAL STANDARD NORME INTERNATIONALE Electricity metering data exchange – The DLMS/COSEM suite – Part 6 1 Object Identification System (OBIS) Échange des don[.]
Reduced ID codes (e.g for I EC 62056-21 )
To adhere to the syntax requirements of protocol modes A to D of IEC 62056-21, the range of ID codes is restricted to meet the typical limitations on digit count and their ASCII representation All value groups are confined to a range of 0 to 99, with specific values outlined in the relevant clauses governing the use of these value groups.
Some value groups may be suppressed, if they are not relevant to an application:
To allow the interpretation of shortened codes delimiters are inserted between all value groups, see Figure A.1 :
Figure A.1 – Reduced ID code presentation
The delimiter between value groups E and F can be modified to carry some information about the source of a reset (& instead of * if the reset was performed manually)
The manufacturer shall ensure that the combination of the OBI S code and the class_id (see
I EC 62056-6-2: –, Clause 4) uniquely identifies each COSEM object.
Display
The usage of OBI S codes to display values is normally limited in a similar way as for data transfer, for example according to I EC 62056-21
Some codes may be replaced by letters to clearly indicate the differences from other data items (see Table A 1 ):

Special handling of value group F
Unless otherwise specified, the value group F is used for the identification of values of billing periods
The billing periods can be identified relative to the status of the billing period counter or relative to the current billing period
There are two electricity billing period schemes outlined in Table 1, each characterized by the billing period length, counter, number of billing periods, and their respective time stamps For further details, refer to section 7.4.1 and IEC 62056-6-2.
In the context of billing periods, a single period is determined by the billing period counter, VZ, where 0 < F < 99 If any OBI S code's value group matches VZ, it signifies the most recent billing period, while VZ -1 indicates the second most recent, and so on The billing period counter can operate in various modes, such as modulo-1 2 or modulo-1 00 Upon reaching the limit, the counter resets to 0 in modulo-1 00 mode and to 1 in other modes like modulo-1 2.
In the range of \$1.01 < F < 1.25, each value of F corresponds to a specific billing period relative to the current one For instance, F = 1.01 indicates the last billing period, F = 1.02 refers to the second last billing period, and so on, up to F = 1.25, which identifies the 25th last billing period.
F = 1 26 identifies an unspecified number of last billing periods, therefore it can be used as a wildcard
F%5 means that the value group F is not used, or identifies the current billing period value(s)
For use of ICs for representing values of historical billing periods, see I EC 62056-6-2: –, 6.2.2

The International Electrotechnical Commission (IEC) is a global standards organization comprising national electrotechnical committees Its primary goal is to promote international cooperation on standardization issues in the fields of electricity and electronics To achieve this, the IEC publishes international standards, technical specifications, technical reports, publicly accessible specifications (PAS), and guides, collectively referred to as "IEC Publications." The development of these publications is entrusted to study committees, which allow participation from any national committee interested in the subject matter Additionally, international, governmental, and non-governmental organizations collaborate with the IEC in these efforts The IEC also works closely with the International Organization for Standardization (ISO) under conditions established by an agreement between the two organizations.
The official decisions or agreements of the IEC on technical matters aim to establish an international consensus on the topics under consideration, as the relevant national committees of the IEC are represented in each study committee.
