An unofficial summary of facts (addresses, types, units, scaling) from the maker's manual. Not affiliated with the maker; values can differ by firmware or model. Always check the device manual before writing (run commands, settings).

| 32-bit order | ABCD |
| Manual address style | Wire address as is (0-based) |
- Addressing: frame addresses in the manual examples (slave 17 = 11h) equal the table addresses (0-based). Read 11 03 01 30 00 03 06 A8 → F, V1, V2 (0130h-0132h), reply 11 03 06 13 88 03 E7 03 E9 7F 04 (50.00 Hz, 99.9 V, 100.1 V); write 11 10 01 56 00 02 04 0A 9D 40 89 4D B9 → Ep_imp (0156h/0157h); relays 11 01 00 00 00 02 BF 5B; DI 11 02 00 00 00 04 7B 59 (printed pp.90-93). The CRCs of these requests match calculation.
- Three typos in the manual's reply examples: the relay reply (11 01 01 02) repeats the request CRC BF 5B (calculated D4 89); the DI reply shows function 01 (its CRC E5 49 is calculated with 02); the FC16 reply shows start 010Ch (its CRC A2 B4 is calculated with 0156h). The CRC columns are labelled Hi/Lo, but the low byte is sent first, as the text on printed p.89 says.
- Communication settings (printed pp.48-49): address 1-247, 1200-57600 bps, 8 data bits, check non1 (no parity, 1 stop), non2 (no parity, 2 stop), odd or EVEN, default EVEN (this screen on EL/KL). The default baud rate was not found in the manual, so it is left empty. Function codes 01, 02, 03 and 16 (Table 4-2, printed p.87).
Registers (47)
«Wire» is the 0-based address in the request frame (PortDock's «0-based» notation). Value = raw × scale. Table: HR holding register, IR input register, CO coil, DI discrete input. Function codes in hex.

Notes
- The 0130h table holds secondary-side values: voltage = Rx × (PT1/PT2) / 10, current = Rx × (CT1/CT2) / 1000, power = Rx × (PT1/PT2) × (CT1/CT2) (Table 4-27). The scales given here assume direct connection (ratio 1); with CTs, multiply readings by the CT ratio (and PT ratio). CT2 = 333 (mV CT) counts as 1.
- A primary-value (actual units) Float table from 0600h (Table 4-28) exists, but the manual does not state the float word order, so it is left out. The settings table from 0100h (Table 4-35) has addresses and names shifted by a row on the page, so it is left out too.
- Page numbers are printed pages (PDF page = printed + 8). Modbus TCP through the Ethernet module (AXM-NET) is not covered here.
Read it with PortDock
- Install the free PortDock Modbus Master and connect with the device's settings.
- On the table toolbar, «Device profile…» → pick this device → «Load». Polling tables, names, types and the Slave ID are filled in (optionally the serial settings too).
- Names carry the unit and scale (e.g. «×0.01 Hz»). Values on screen are raw — multiply by the scale.
- To test your program without the device, PortDock Modbus Slave's «Emulate device…» serves the same map with example values.
