    "Modbus RTU on the native RS-485 or RS-232 port (auto-sense by default); Modbus ASCII and TCP are not supported. FC03/FC04 read, FC06/FC16 write, at most 100 registers per request.",
    "Addresses are the one-based numbers of the manual: 30101 = input register 101, 40001 = holding register 1.",
    "Floats are IEEE 754, big endian, high word first; a float must be read from its first (odd) address.",
    "Energies are split into five signed parts (× 10^9, 10^6, 10^3, 1, 10^-3); add them for the value.",
    "Configuration changes need the password in the first element of each table. Setpoints, logs, oscillography, TOU and the other tables of appendix A are left out."
