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.

Series 200 and 700 Power Meter (PM200, PM700, PM750) Register List with 3.050 firmware functionality

Addresses are the register numbers of the register list (Modicon numbering, 1-based): the address on the wire is the register number minus 1.
The 4000 series holds integers scaled by the four scale factor registers (4105 to 4108): value = register x 10^scale factor, in the unit shown. The 1000 series holds the same values as floating-point numbers, already in engineering units.
Power factor registers 4009 and 4048: a negative signed value is reported as value + 32768 (see the register list).
The alarm configuration blocks (4140 and following, 16 registers per alarm position) are written with the command interface and are not in this map.
Registers that exist only on some of the models say so in their description.
