    "Set P0700 = 5 (USS/MODBUS on RS485), P2023 = 2 (Modbus) and power-cycle the inverter; P2021 sets the station address (1 to 247), P2010 the baud rate, P2034 the parity (default even) and P2035 the stop bits (default 1).",
    "Addresses are the manual's register numbers: register 0 is 40001, so the map uses holding addresses 0-based. Only function codes 3, 6 and 16 are supported.",
    "Two register blocks overlap in function. 40001-40062 is the older compatible block; 40100-40111 is the process-data block (control word, setpoint, status word, actual value) and 40200 onward is the parameter-data block.",
    "Values with a scale factor in the manual are already multiplied by it on the wire (frequency 50.00 Hz reads 5000). Setpoint and actual-value percentages (40003, 40044) and the process-data words 40101 and 40111 are relative to the reference frequency P2000; for the process words 0x4000 = 100 %.",
    "Registers 40014/40015 and 40200-40203 write BICO inputs: only 0 or 1 is accepted and it replaces the previous connection. Digital outputs 3-4 and digital inputs 5-6 exist only with the optional I/O Extension Module.",
    "The manual lists no register with a fixed value, so the map has no reference values.",
    "Written from the manufacturer's manual; not tested on a device."
