- Registers are 0-based. Bit numbers: 0 = LSB, 15 = MSB. 32-bit values are assumed low word first (CDAB), as on the Unipi extensions; the manual does not state the word order.
- Registers marked Reserved in the manual are left out.
- Transport is not stated in the manual; Modbus TCP on port 502 is assumed.
- All registers in this map are on Unit ID 0; the manual lists no Unit ID 1 tables for this model.

No registers match
Try part of the name, an address (decimal or 0x hex) or clear the filters.
