: The most advanced mode, which allows for the use of other protocols (like DLMS/COSEM) to be tunneled through the IEC 62056-21 connection for high-level security and complex data structures. The Role of ASCII and Readability
IEC 62056-21 is more than just a technical specification; it is the "common tongue" of the metering world. By standardizing the physical and logical layers of local communication, it has enabled interoperability across the global energy sector, ensuring that energy data is accessible, accurate, and secure.
