INTERFACE SPECIFICATION –Physical Layer Mechanical and Electrical Interface for
|STS 101-1 describes the de-facto industry standard(s) "credit reader port" mechanical and electrical interface as implemented by existing prepayment meters, but with minor deviations and enhancements. |
The specification aligns with IEC 62055-52.
|STS101-2 ||ELECTRICITY METERING – PAYMENT SYSTEMS |
Standard Transfer Specification – Physical Layer Protocol for a two-way virtual token carrier for remote connection over COSEM
|This document specifies the requirements for a new token carrier (STS_COSEM_TC) for the transfer of tokens using standard DLMS/COSEM client/server protocols and a selection of COSEM interface classes.|
|STS200-1 ||COMPANION SPECIFICATION - |
Generic classes for meter function objects
|The Specification introduces, describes and defines the concept of Meter_Function_Objects, which provide for specifying the functionality of the meter without imposing design-specific or technology-specific constraints on the actual meter implementation.|
|STS201-1 ||COMPANION SPECIFICATION– |
Meter function object: RegisterTable for payment meters
|This companion specification is intended to document and adopt the de-facto industry standard "credit reader port" functionality as implemented by existing prepayment meters. |
The specification is for complementary use with companion specification STS 101-1 and is envisaged by IEC 62055-52 as an instance of a MeterFunctionObject.
