A simulation of a communication between a smart meter and a data concentrator unit conformed to DLMS/COSEM upon an HDLC profile

Abstract

This article describes communication between a simulated smart meter and a simulated data concentrator unit (DCU) conformed to DLMS/COSEM. The communication is based on the three-layer, HDLC-based profile. A DLMS/COSEM library was developed. The APDUs generated by the library were the same as those from examples in the standard book. Furthermore, employing this library, the data concentrator unit can read successfully commercial DLMS meters.
