400051 Fieldbus status word (SW). See section Status word for the ABB Drives
profiles on page 341.
400052 Fieldbus actual value 1 (ACT1)
400053 Fieldbus actual value 2 (ACT2)
40054 Fieldbus data in/out 13 (Drive parameter 58.47 Data I/O 12)
……
40065 Fieldbus data in/out 24 (Drive parameter 58.58 Data I/O 24
400101…409999 Register address (16-bit drive parameter) = 400000 + 100
× group +
index
Example: Modbus register address to drive parameter 03.18 is
400000 + 100
× 3 + 18 = 400318
Drive parameter access (32-bit drive parameter) = 420000 + 200
× group
+ 2
× index
Example: Modbus register address to drive parameter 01.27
420000 + 200 × 1 + 2 × 27 = 420254
