Abstract—The communication technologies for automatic meter reading (smart metering) and for energy production, distribution and consumption networks (smart grid) have the potential to be one of the first really highly scaled cyber-physical applications. Due to the characteristics of the energy market, which is multi-“media”, multi-utility, and multi-vendor on the different levels of the value chain, standards are of key importance to guarantee interoperability and seamless communication. For the European markets, the EN13757 M-Bus standard family has become the standard of choice. However, the standard family is very flexible and can be adapted to the various requirements. This paper shall give an overview on the existing variants. The recent and actual advances are described in more detail. All information is backed by the experience from a fully independent implementation of the EN131757-4 of the authors’ team.
