The standard is structured around several modes of operation, ranging from simple data readouts to complex, password-protected programming:
: These involve fixed or auto-baud rate switching for simple data transmissions.
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. Importance in Modern Metering
