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 |
|---|---|---|---|---|
| Firmware | Firmware package version | holding 4096 | string[8] | |
| Model | Model number | holding 4120 | string[16] | |
| Serial number | Serial number | holding 4136 | string[16] |

- Register addresses are the absolute decimal addresses of the manual (Modicon 40001 is address 0).
- Only function code 3 is supported, so every register is read-only here. Modbus RTU and Modbus TCP are supported; the serial settings are on the UPS display.
- Status and alarm registers are bit words; bit 0 is the least significant bit and reserved bits are left out. Bits are atomic within one register only.
- Reading a reserved register alone returns an error; a block read that starts on a valid register returns zeros for undefined ones.
- The scale of registers 4867-4869, 5123-5125, 5379-5381 and 6144-6153 differs from the Galaxy VS and GPX maps.
