One of the defining features of IEC 62056-21 is its use of . Unlike more modern, purely binary protocols, the data packets in this standard are often human-readable. A typical data telegram includes a "Sign-on" sequence, a vendor identification code, and the meter's data registers (such as total energy consumption or peak demand), followed by an end-of-character sequence and a checksum for error detection.
