Smart X96-5G~J Protocol

Source: Eastron, "Smart X96-5G~J Protocol"

Measurements are float32 input registers (FC04); settings are holding registers (FC03 read, FC16 write).
Settings marked KPPA need the password (default 1000) written to the key parameter programming authorisation register first.
Not in this map: the 2nd-63rd harmonic blocks (0x0192-0x0479), the DO alarm set-up (0x0400-0x0413), the event log (0x0500-0x0577) and the clock (0xF000).
