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.

  • Addresses are the manual's register numbers (40001 = holding register at protocol address 0).
  • Measured values are float32 by default. Register 40050 can switch them to 16-bit integers in the first register of each pair, scaled by range factors (manual table 5-1); this map assumes the float format.
  • Bits are numbered as in the manual's register/bit notation (40129 / 20 is bit 0 of register 40129).
  • Not in this map: harmonic 2 (40500-40738), limit value counters, analog I/O and limit value group parameters (40901-41210).
