General Requirements


Constant values specified in Table 7.3.8a shall be fixed before operation and shall be immutable save via a firmware upgrade. This is to ensure consistent functioning and guard against potential attacks. Except where explicitly required by this Section 7.3, a Device shall not expose any part of any DLMS COSEM object, either for the writing of an attribute or for the invocation of a method that could, if used, constitute a Critical action.

For Devices which are not ESME or CHF (so where deviceType <> 1 or 2), the GBCS does not require the implementation of any DLMS COSEM objects.

All Devices which are ESME (so where deviceType = 1):


  • shall implement all of the DLMS COSEM objects, attributes and methods detailed in ‘SMETS Required Objects’ tab of the table in Section 20, and expose the specified attributes and methods over its network interface; and

  • shall have the constant values set for the DLMS COSEM attributes specified as requiring constant values in Table 7.3.8a, and shall ensure that such values cannot be amended, save via activation of new firmware.
