    "Measurements are float32 input registers (FC04); settings are float32 holding registers (FC03 read, FC16 write, one parameter per write).",
    "Requests must cover an even number of registers; at most 30 values per read.",
    "Protected settings need the password (default 1000) written to the password register; it times out after one minute unless the password or password lock register is read.",
    "The tariff registers (1300h-1382h) are for the two-tariff SDM630MCT-2T."
