  "notes": "The ACS580 has no native Modbus TCP port; this map applies to an ACS580 with the FMBT-21 Modbus/TCP adapter module, which acts as the Modbus server on port 502. The adapter does not use the unit identifier, so 1 is sent as a harmless default. Register numbers follow the adapter's ABB Drives - Enhanced profile, which is 51.02 Protocol/profile default value 1: control word, REF1 and REF2 at 400001-400003, status word, actual 1 and actual 2 at 400051-400053, DATA OUT 1-12 at 400004-400015 and DATA IN 1-12 at 400054-400065. Settings are reached as drive parameters: 16-bit parameter access address = 100 x group + index - 1 (e.g. 30.12 = 3011), 32-bit parameter access address = 20000 + 200 x group + 2 x index - 1 (e.g. 01.01 = 20201); both assume address mode 0 (parameter group 51). Monitoring rows use the 32-bit access registers because their scaling is fixed by the firmware manual (100 = 1 rpm, 100 = 1 Hz, 100 = 1 A, 10 = 1 %, 100 = 1 V), while 16-bit values are scaled by group 46 and therefore by the configured speed/frequency scaling. Default profile settings: 51.20 timeout 10 (0.1 s steps, so 1.0 s), 51.21 timeout mode 2 (control RW). Call 51.27 FBA A par refresh (write 1) after changing adapter settings."
