  "notes": "RS-485 device: reach it through a Modbus RTU-to-TCP gateway. Factory settings are P0308 = 1 (serial address, also the unit ID used here), P0310 = 1 (19200 bit/s), P0311 = 1 (8 data bits, even parity, 1 stop bit) and P0312 = 2 (Modbus RTU-1), i.e. the 19200 8E1 block above. Sources: WEG \"CFW500 Modbus RTU User's Guide\", document 10002253377, revision 04, 06/2025 (https://static.weg.net/medias/downloadcenter/h73/ha4/WEG-CFW500-modbus-rtu-manual-10002253377-en.pdf), section 5.2.1: \"all parameters of the equipment are available as 16-bit holding registers. The data addressing is done with the offset equal to zero, which means that the parameter's network address (Net Id) corresponds to the register address\" (P0680 = 680, P0683 = 683); and WEG \"CFW500 V2.2X Programming Manual\" 10002296099 (https://static.weg.net/medias/downloadcenter/h69/h0f/WEG-CFW500-programming-manual-10002296099-en.pdf) chapter 18 for the readout ranges and chapter 4 for the serial parameters P0308-P0312. Scaling: the programming manual publishes each readout's full-scale range with its decimals (0.0 to 200.0 A, 0.0 to 500.0 Hz, 0.0 to 6553.5 kW, -1000.0 to 1000.0 %, -1.00 to 1.00), which is the factor stored per row. P0001/P0002 and P0683 depend on P0208/P0209/P0210 (scale, unit and decimal places) and therefore carry no fixed factor. Deliberate omissions: the SoftPLC marker map and the parameter groups beyond the readouts, ramp times, speed limits and serial settings are not transcribed. P0012/P0013 are bit fields over the digital I/O; the individual bits are named in the programming manual but not listed here as separate rows."
