Reading the time and date (register 717 / 0x2CD):
Important: the 3 registers from 717 must be read on 1 request.
1
register:
st
High byte: hours
Low byte: minutes
2
register 2:
nd
Most significant byte: day
Low weight byte: month
3
register 3:
rd
word: year
Example: January 31, 2022 at 4:07 p.m.
1
register (HHMM) : 4103
st
2
register (JJMM) :
nd
3
register (YYYY) :

Values displayed for the time schedules (Modbus addresses: 300, 400, 500 and 600):
The time is codified on 1 register in the following manner:
hh:mm → (hh x 60) + mm to be transformed into hexadecimal
e.g.: 22:30 → (22 x 60) + 30 = 1350 (decimal) = 0546 (hexadecimal)
If no time is programmed, the registry must have the value FFFF.
Example for Monday with:
Phase 1: switching on at 6.30 a.m. / switching on 10.30 p.m.
Phase 2 & 3: no schedule scheduled
Monday
