| Hiking DDS238-2 ZN/S energy meter: Modbus holding registers | |
| register(s) word order data format meaning unit (symb.) | |
| 0000h-0001h hi-lo unsigned? total energy decawatt-hours (daW·h) | |
| 0008h-0009h hi-lo unsigned? export energy¹ decawatt-hours (daW·h) | |
| 000Ah-000Bh hi-lo unsigned? import energy¹ decawatt-hours (daW·h) | |
| 000Ch unsigned? voltage decivolts (dV) | |
| 000Dh unsigned? current centiamperes (cA) | |
| 000Eh two's compl. active power watts (W) | |
| 000Fh unsigned? reactive power¹ watts (W) | |
| 0010h unsigned? power factor | |
| 0011h unsigned? frequency centihertz (cHz) | |
| 0015h:hi octet unsigned station address <n/a> | |
| 0015h:lo octet ² baud rate baud (Bd) | |
| 0016h-0017h hi-lo? unsigned? trip energy¹ decawatt-hours? (daW·h) | |
| ¹ "special order function" | |
| ² unsigned, with value mapping: | |
| 1 = 9600 Bd | |
| 2 = 4800 Bd | |
| 3 = 2400 Bd | |
| 4 = 1200 Bd | |
| (there may be more values) | |
| Register 0015h is writable. The meter does not understand the 'write sigle regi- | |
| ster' function code (6), only the 'write multiple registers' function code (16). |
