Defines 4 profile specifications: - the DLMS/COSEM SMITP B-PSK PLC Profile; - the Original-SMITP B-PSK PLC Profile; - the Original-SMITP IP Profile; - the Original-SMITP Local data exchange profile.

This Technical Specification contains 4 profile specifications

1. the DLMS/COSEM SMITP B-PSK PLC Profile (clause 4)

2. the Original-SMITP B-PSK PLC Profile (clause 5)

3. the Original-SMITP IP Profile (clause 6)

4. the Original-SMITP Local data exchange profile (clause 7)

The DLMS/COSEM SMITP B-PSK profile (see Clause 4) defines the use of the CLC/TS 50568-4 communication protocol and methods to access and exchange data modelled by the COSEM objects of EN 62056-6-2 via the EN 62056-5-3 application layer. This clause is in line with the DLMS/COSEM suite as described in EN 62056-1-0.

The Original-SMITP Profiles (Clauses 5, 6 and 7) define the use of the CLC/TS 50568-4 communication protocol and methods to access and exchange data modelled by the Original-SMITP Data Model (clause 10) via the Original-SMITP Application Layer (Clause 9). These clauses are not part of the DLMS/COSEM suite as described EN 62056-1-0.

NOTE The expression Original-SMITP refers to the open Smart Metering Information and Telecommunication Protocol originally developed and maintained by the Meters and More Association (see Foreword). The Original SMITP specifications were developed prior to the availability of the DLMS/COSEM SMITP B-PSK profile.
