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.

- Addresses are the register numbers of the register list (Modicon numbering, 1-based): the address on the wire is the register number minus 1.
- Registers marked RWC in the register list are changed through the command interface, so they are listed as read-only.
- Values the meter cannot provide read as the N/A value of their data type (0xFFFF, 0xFFFFFFFF, 0x8000 or a float NaN).
- Power factor registers are four-quadrant values from -2 to 2, not plain power factors: 0° = 1, 90° = 0, 180° = -1, 270° = 2. Above 1, the power factor is 2 minus the value and leading; below -1 it is -2 minus the value and leading; otherwise it is the value, lagging (unity at ±1).
- The register list does not state the order of the two registers of a 32-bit value; this map uses the order of the PM5000 family (most significant register first). If the values look wrong on a device, try little word order.
- Registers that exist only on some of the models say so in their description.
