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.

Sources and notes

  • Addresses are the Modbus offsets of the manual. Values are read with FC03 or FC04; settings are written with FC10 and commands with FC06.
  • Read every value from its first register with its full length: a read that starts or ends inside a multi-register value returns an error. The I&M data is read and written as a whole block (64001-64027 and 64028-64116).
  • Factory settings of the RS-485 versions: address 126, 19200 baud, 8N2. The Ethernet versions use Modbus TCP, port 502.
  • The 65 A devices have a fixed primary and secondary current; those two settings can be written on the 5 A devices only.
  • Not in this map: the status bits read with FC01/FC02, the 10 s and 15 min load profiles and the daily and monthly energy history read with FC20 (files 1, 2, 90 and 91), the user-defined FC100 and the Modbus device identification (FC43).
