Metering Protocol Laboratory
The implementation of Open Protocol for Static Energy Meter /
Smart Meter is one of the mostessentially required key features in
present scenario for implementation of Automatic MeterReading
(AMR), Advanced Metering Infrastructure (AMI) and Smart Grid across
the country toensure interoperability of Energy meters.
The open protocol based on IEC 62056 helps to overcome most of
the challenges regardingdata acquisition of utilities, uniformity
and homogeneity among various energy metermanufacturers in
India.
Subsequently, BIS has formulated India Companion Specification
(ICS) and published
- IS: 15959 (Part 1): 2011- “Data exchange for electricity meter
reading, tariff and loadcontrol – Companion specification” (Part 1
for Static Energy Meters). - IS: 15959 (Part 2): 2016 (Smart
Meters) as part of IS 16444 (Part 1): 2015 - IS: 15959 (Part 3):
2017 (Transformer operation Smart meters) – “Data exchange
forelectricity meter reading, tariff and load control- Companion
specification for Smart meters” aspart of IS 16444 (Part 2):
2017.
This companion specification covers Indian specific requirements
for design of open protocolenergy meters / smart meters. The open
protocol for Static & Smart Energy meter formulatedas ICS will
also serve as the backbone for Advanced Metering Infrastructure
(AMI).
In order to meet the above mentioned DLMS protocol testing
requirements of utilities andmeter manufacturer’s, CPRI has
established comprehensive state-of-art technology ‘Meteringprotocol
Laboratory’ at Bengaluru, Bhopal and Noida Units. By using latest
versions ofConformance Test Tool – CTT and Functional Evaluation
Tool – FET both Static EnergyMeters and Smart Meters will be
verified for their compliance respectively. Additionally,
Communicability for Smart Meters can also be verified.
The laboratory’s testing and developmental assistance services
has been utilized by manyIndian / overseas manufacturers,
Utilities, Integrators etc.
CPRI is a member of DLMS UA (Device Language Message
Specification User Association),Geneva. The CPRI Test Reports will
carry the logo of DLMS UA as shown below.

Metering Protocol Laboratory
Our Metering Protocol Laboratory has been duly accredited by (i)
NABL as per the StandardISO/IEC 17025:2005 and (ii) BIS for its
testing activities for DLMS/ COSEM with respect torelevant
Standards and the major tests carried out are listed below:
Conformance Test in general accordance with IEC 62056 The
purpose of the DLMS/ COSEM (IEC 62056) conformance certification
scheme is tovalidate that the Implementation under Test (IUT)
correctly implements the features selectedfrom the features
available in the DLMS/ COSEM specification.
As part of testing, CPRI has DLMS/ COSEM test facility for
Energy meters (Static and SmartMeters) supporting HDLC, TCP-IP
based (wired and wireless) communication profiles includingsecurity
layers for data level protection in Smart meters.
Parameter verification in general accordance with various ICS
for Energymeters (Static and Smart meters) Parameter verification
is carried out using Functional Evaluation Tool (FET) an
automatedTEST tool in accordance with IS 15959 (Part 1): 2011, Part
2: 2016 and Part 3: 2017 and aspart of IS 16444 (Part 1): 2015 and
IS 16444 (Part 2): 2017. The tool verifies the
parametersimplemented in the meters to be in line with the ICS. FET
can access all the associations (PC,MR, US for static meter and PC,
MR, US, PUSH, Firmware Upgrade & IHD for Smart meter) toread /
write / modify the data. Test cases supported by FET for Static
Meter:
