Device identity
What a tool can read to check that this map fits the connected device (SPEC.md section 4.7). Registers with a role are read like any other register.
| Role | Register | Address | Type | Values |

Sources and notes
- Countis E34/E44 MODBUS active energy meters communication table · version table V 200.53, 2017-08 Whole table except reserved, command, record and date registers
- One table for Countis E34 and E44.
- Addresses are the decimal addresses printed in the table, sent as written (address_base 0). Registers are read as holding registers.
- Scales follow the table's unit column (for example V/100 becomes a scale of 0.01); energy counters are in kWh, kvarh and kVAh, or in 10 Wh steps in the second set.
- The table gives neither function codes nor byte or word order: big-endian with the high word first is assumed (Socomec convention). Not tested on a device.
- Values the table types as 8-bit sit in one 16-bit register and are read as uint16. Date and time, 64-bit, record and command registers (resets, tariff selection) are not mapped.
